If you attempt to look up the pedigree of the David Austin roses of the past decade or so, that is what you'll see. As a "fellow explorer" in rose genetics, (No, I am not drawing any comparisons between myself and Mr. Austin) I find that rather annoying and disappointing. I'd like to know what went into the making of some of his current roses. Perhaps he is just protecting what he regards as "proprietary information", or maybe he just doesn't want us to know that he is using the likes of 'Fragrant Cloud' or (gawd forbid) 'Tropicana' to achieve his results. Who knows.
I gravitate much more towards Ralph Moore's way of thinking about such matters. Allow me to paraphrase him: What have I got to lose by sharing information about parentage of my roses? You can see my "recipe" for a rose, but without my personal "ingredients", you can't make the same "cake". And besides, by the time a rose makes it to market, I've already moved ahead by six or eight years or more, and so why would I care if someone tried to duplicate my results?
Makes sense to me. I'd rather describe in a fair bit of detail what I am working on and how I am getting there. Half the fun is getting pleasing results, the other half is sharing what I've learned in the process.
And just because it doesn't feel right to write a blog post without a picture, we have today: 19-02-03 from a cross of 'Joycie' X 'Crepuscule'.

As you can probably decipher from the code number of this one (cross #53, year 2003, seedling #8 of that cross) I have had this for several years now and I've been watching its performance in the garden. I made the cross hoping for a percentage of repeaters, and yet none of the dozen or so I kept for testing have been repeaters. However, this one has other merits: it is totally Blackspot free (that is remarkable in this climate, where Blackspot rules) and is an aesthetic winner. It also bears a delicious fragrance, influenced by (but not a carbon copy replica of) its pollen parent, 'The Yeoman', whose Anise-scented blooms are anathema to some, and heaven-on-earth to others.
I have started propagating 53-03-08 and have sent a few plants out for testing on other regions. I don't exactly plan on releasing this commercially; I mean, do we really need more once-blooming pink roses? (Obviously rhetorical: my answer is no) Still, it is a lovely, easy to care for shrub. It appears to max out at about 7 feet tall and a bit wider, with an arching outline and no inclination to sucker widely.
Saturday, December 18, 2010
The idea here is improved winter hardiness in the yellow color range. Both parents are renowned for their ability to thrive in harsh, wintry climates, and so I hope to see some of that persist in this cross. At this point only two seedlings remain, and this is the nicer one of the two. Curiously, it has inherited the peculiar Cinnamon-like fragrance of its Canadian parent, 'Morden Sunrise'.
Its rather nice to have a late December bloom as pretty as this, just before Christmas. One might almost think spring was just around the corner. (HAH!)

A seedling from around 2000: 'Charles de Mills' X 'La Belle Sultane'. It has been nicknamed "Farside deMills", a name that distinguishes it from its neighbors, by proximity.
This is a once-blooming hybrid, suckering growth habit, making an ever-widening thicket of 3 foot tall canes. You can see the influence of 'La Belle Sultane' in its Damask-like sepals, while the bloom form is clearly that of its seed parent. A lovely thing, although it has languished in test bed #1 for many years, having been disqualified for commercial purposes. (too hasty, perhaps?) Maybe I ought to auction off naming rights....hmmm.

This is a movie made using the content from a self-published book of my rose photos, entitled The Uncommon Rose Collection, published December 2010. There is a high resolution version available on YouTube here as well.
Tuesday, November 30, 2010
I can't quite make the photograph reflect the subtleties of hue that the bloom actually possesses; its not just a red, its that odd shade of Chinese red with an overlay of "smoke bush" purple that several of the "brown" roses has. Not even Photoshop can tweak it to accuracy. Oh well.
So, why the title of this post? Because I have been watching this seedling for three years now (pollinated in 2006, germinated in April of 2007) and I've been hoping it might eventually show some vigor and enthusiasm. It hasn't. It has never exceeded 18" tall and prefers to flower rather than build infrastructure. It also tends to die back rather badly even in our mild winters. I can just hear what you're thinking: maybe it just needs to be budded onto stronger roots? Well, yes....odds are that would improve its performance, but Since the rose industry is in such trouble now, I am insisting that any of my selections have to prosper on their own roots. Bud grafting just isn't an option anymore. Distribution of new cultivars may soon be the job of the many small "boutique" and home-grown nurseries, and few (if any) of those nurseries are going to have the ability or the willpower to propagate by bud grafting; it will all fall to propagation by cuttings. I need to pay attention to that, and assume that is where the future of commercial roses lies.
Anyway, it is a remarkable flower when it is doing well, with its 'Pat Austin' shaped cupped blooms and its muted cinnabar hued petals. Its just a shame the damn thing doesn't grow worth a hoot. Maybe it has something to offer as a pollen parent, maybe I'll give that a try next Spring.

As the years go by, you encounter many aficionados of The Rose who introduce you to some very curious things along the way. Certainly Ralph Moore has shown me, by far, the greatest number of rose oddities and today I want to introduce you to one of these.
This is the Reversion Sport of The Green Rose, R. chinensis viridiflora. It was discovered by Moore at Sequoia Nursery many years ago, growing as a lone branch on his mother plant of viridiflora, bearing semi-normal pink blooms. It doesn't always make such "regular" looking flowers as you see here; often they are halfway between normal and the odd green sepal formation of viridiflora. When they appear as ordinary pink China blooms, they are at their best.
As you can see, the Reversion Sport does produce normal reproductive parts, and in fact the plant will set seed if allowed to. (I don't recall whether these germinate or not, but I'm sure I have sown the seeds years ago) The appearance of this sport lends credibility to the supposition that viridiflora sported from 'Old Blush' at one time. Perhaps that's true! Curious, eh?

Well, its a kind of layering. I take any cane of a rose that can be bent to reach the soil surface (plants in pots or in the ground, either works) and bury a section of the cane under the soil, leaving a few inches of the growing tip exposed. I do not injure the cane in any way, nor do I use rooting hormones of any kind. In fact, the whole procedure is a rather lazy one; I just grab a cane when I happen to be near a plant I want to propagate, paddle out a bit of a hole in the soil surface and shove the cane in and pat it down. Nothing could be easier. In most cases, I found that these cane were rooted enough to remove the shoot and pot it up in four to six weeks.
Shown here is a shoot of the Spinosissima 'Suzanne', five weeks after pushing the cane into the soil. In the top photo, note the red arrow in the photo which is pointing at the original cane that was pushed under the surface, at just about the point that it enters the soil. Click on any of the photos to view a larger image.
You can see that it has not only produced a significant root system of its own, it has pushed up new shoots from below the soil surface to start forming a brand new mini-thicket of its own. The shoot was cut from its parent cane and potted up in a gallon can, as you can see here. It did not suffer any transplant shock at all (bear in mind I dug it on a cool, cloudy day) and appears ready to make a go of it. What could be easier?!

I've grown Ralph Moore's "Orange Moss" ('Mark Sullivan' X 'Golden Moss') for quite a few years and I have come to love it for the many things it is, and lament it for the many things it is not. It is a remarkable leap forward in the breeding of the modern moss roses, something Ralph pioneered in the fifties. It is also deeply flawed, with its awkward, sprawling growth habit, sparse blooming habit, and insistence on producing an expert crop of mildewed growth from August onwards. And yet, when it does flower, the buds with their rich orange hues splashed with a smoldering red are remarkable. The open blooms are pure joy; glowing pure color and striking anthers beautifully displayed, plus it bears the richest fragrance, reminiscent of Orange Tang drink mix from my childhood!
Ralph told me personally, and documented it in writing also, that Orange Moss, while enthusiastically fertile as a pollen parent, did not set seeds. Perhaps it is a climate difference, but one of my greenhouse-kept specimens of it produced three hips in 2009. I did indeed save them and prepared the seeds along with all the rest of the 2009 crop, sowing them in March of this year. Three seedlings resulted, one of which you see here.
Two of the three were dreadfully mildewy creatures, barely holding on to life all Summer. One appears to be declining, while the second is holding on, even while consumed by Mildew. The third one, as you can see, is clean as can be, with deep green glossy foliage. I am potting this one up into a gallon can this AM, and with any luck I will see a flower next Spring. I hope that it might contain the genes for both mossing and the rich coloring of its parent. Remontancy is unlikely, I'm guessing, but who knows.
Doesn't that foliage just scream "I'm a goer!"?

79-02-PFC X 'Therese Bugnet'. The seed parent is R. foliolosa X 'Little Chief' and strongly resembles 'Basye's Purple'. See: 79-02-PFC
This is the kind of thing I like to see in my work nowadays, and this is much more the direction my work is taking; a lot of native species involvement and heavy use of plants like 'Therese Bugnet'. (which I am beginning to regard as a superb shrub. Now all we need is to improve in the rate of rebloom) No, I haven't seen bloom on any of these hybrids yet, but I didn't expect to till 2011 anyway. Many of these near-species crosses take at least a full year to start blooming anyway.
I also have a group of about 20 selections of R. foliolosa X 'Therese Bugnet' that are very similar in habit, but with even greater vigor, and in general, larger spaces between internodes. The R. foliolosa X 'Therese Bugnet' seedlings are also very sparingly thorned, some nearly thornless, in fact. I am looking forward to seeing first bloom on these in the Spring!

I recognize, and wish to emphasize, that any list of highly disease resistant varieties compiled by one person in a specific region may be meaningful only to that particular site and/or geographic region. A cultivar that performed outstandingly in my garden may be a disaster in the South or the East, and vice versa. Keeping that in mind, the first group is a list of roses that I designate "Little or no infection". This group includes anything that kept at least 90% of its foliage even if it did suffer some Blackspot infection. Some cultivars had an infection rate of zero and these are marked with a +
Indian Love Call
Duchesse de Rohan
The Green Rose (R. chinensis viridiflora)
Soupert et Notting
Tiffany+ (now there's a surprise!)
Mme. de LaRoche-Lambert
Konigin von Danemark
Great Maiden's Blush (some years it gets some infection and as such, would be placed in the second category.)
Tour de Malakof+
Ville de Bruxelles
Souvenir de Claudius Denoyel
Wedding Cake (some years it fits in category 2 rather than here)
Pompon de Bourgogne+
William Shakespeare 2000 (NOT the original William Shakespeare, which has very poor disease resistance)
Capitaine John Ingram+
Mrs. B. R. Cant
Golden Wings (some years it fits in category 2 rather than here)
Vineyard Song (some years this gets a + for complete immunity to Blackspot, 2010 included)
Dorothy Perkins+ (although, as most are aware, it Mildews quite readily from Mid-Summer on)
Errinerung an Brod (some years it fits in category 2 rather than here)
Blanc de Vibert (a very poor plant in most other ways, however)
R. centifolia cristata
Mutabilis (some years it fits in category 2 rather than here)
Yellow Lady Banks (although none of the Banksieas are reliably Winter hardy here and have been removed from the collection)
Plus all of the Gallicas, with the exception of those that show conspicuous China or Hybrid Perpetual influence: these get some disease, often Mildew as well.
I include all of the North American species I grow as well. My R. clinophylla, two plants seed grown, from India, both suffer some Blackspot infection, although minimal.
List 2: Varieties that kept at least 75% of their foliage in spite of infection, and which outgrew disease quickly, with little impact on overall plant health.
Incantation (some years it fits in category 1 rather than here)
Reine des Violettes
Rose de Rescht
R. damascena bifera
Souvenir de la Malmaison (although often plagued by terrible Mildew)
Mrs. William Paul
Mme. Caroline Testout (some years it belongs in the 90% clean category)
Chianti (some years it doesn't belong in either group, as it does occasionally defoliate almost completely)
Variegata di Bologna (sometimes it doesn't fare well enough to be on this list)
Yolande de Aragon (some years yes, some years no)
Portland from Glendora
Ghislaine de Felighonde
Marchionesse of Londonderry
Closer to Heaven
Belle Poitvine (and all of the "purebred" Rugosas)
Out of Yesteryear
Sutter's Gold (some years not so good)
Cuthbert Grant (This season it is one of the 90% and up varieties)
Fa's Marbled Moss
Mme. Alfred Carriere
The third list I have compiled is one assessing the many Miniatures I have in my archive, the vast majority of which are Ralph Moore hybrids. The following group indicates those which maintained at least 85% of their foliage at all times, whether infected with Blackspot or not. Some cultivars were totally immune to Blackspot in my garden and are marked with a +
Sweet Fairy +
Golden Century (near 100% immunity some years)
Blue Mist +
Hall of Flowers
Red Wand, climber +
Cinderella (near 100% clean)
Apricot Twist + (reliably immune to all disease in all years tested)
Cal Poly +
Rose Gilardi (near 100% immunity some seasons)
Magic Wand +
Unconditional Love (near 100% clean some years)
I'm sure I have missed a few plants in compiling this list, which is easy to do when surveying a collection of over 2500 varieties. I'll remind readers that this list in no way in meant to indicate that all of these roses will perform similarly in all climates and in all sites/soil conditions. I know for a fact that some of the historic (OGR) varieties I list as highly disease free fare quite poorly in other regions. Still, it should at least provide some insight as to general health of the varieties listed.
*One exception to this is the Ralph Moore collection, which is one of only two or three complete collections of commercially released Moore roses to be seen anywhere. As the curator of such a collection I feel the need to continue spraying these to keep them in good health, as I have only one specimen each of the majority of these.

One of the most important contributions Ralph Moore made to modern roses is striping. Before Ralph took on the task, there were really no striped roses of note aside from a few OGRs that displayed the characteristic. 'Ferdinand Pichard' (bred by Tanne, France, 1921) was about the most modern striped rose available to growers, and it was in fact 'Ferdinand Pichard' that Ralph turned to in order to mine its genetic secrets for striping. Moore's first successful cross used the Floribunda 'Little Darling' as the seed parent, as it so often turned out to be the rose that would repeatedly serve as a "door opener" for Moore, paving a way forward where other roses failed to deliver. (Note that by today's standards, 'Little Darling' is an imperfect rose with many flaws, and has largely been abandoned as a breeder. However, at the time Ralph was working with it, it offered unique opportunities: fertility, pliability and the ability to breed fertile offspring even when crossed with the most difficult cultivars.)
The seedling pictured above, a cross of 'Anytime' X 'Shadow Dancer', was gifted to me about 6 years ago by Ralph personally, as he was considering it as a commercial introduction and was seeking more feedback about its performance. (In Visalia, apparently, it grows as a climber, but here in my climate it has not exceeded four feet.) You can see the 'Anytime' coloring it its blooms, right down to the curious lavender cast often seen in the center of the aging blooms. It is generous with blooms and often flowers in clusters of 7 or more, making for quite a display. It has no fragrance (not surprising, considering its pedigree) but has decent foliage health and good vigor.
Unfortunately this seedling never did make it into commerce while Ralph was alive, but with Texas A&M now managing the vast Moore collection of un-introduced seedlings, it might yet have its day in commerce. For now, I will experiment with it as a breeding plant. My first tests indicate that it is quite willing to pass on those striking 'Ferdinand Pichard' stripes that Ralph worked so hard to distill.

141-09-02: un-named diploid Polyantha X 'Home Run'.
The rose used as a seed parent in this instance is a diploid Polyantha developed by David Zlesak and shared with me for breeding purposes. I don't have any record of its exact parentage, so I best not quote what I remember in case I'm wrong! The Zlesak Poly is a cluster flowering dwarf plant halfway between a Polyantha and a modern miniature in style, with clusters of 2" double, cupped crimson blooms bearing a pale, near-white reverse. To my nose, it offers a very respectable "fresh" scent. It is a very attractive little shrub and I hope David might consider it as a legitimate garden shrub of commercial value.
I used the "Z Poly" last year in conjunction with a number of other diploids with the goal of maintaining a strongly pigmented diploid line. I also included Carruth's 'Home Run' in the list of pollen parents, as it is a triploid and will presumably give both haploid and diploid pollen grains, and so this cross, 141-09, should include a mix of diploid and triploid offspring.
Many of the 141-09's were very good in terms of color, vigor and foliage. I selected about 15 seedlings for evaluation. Most are in shades of deep red or crimson, and most are singles or nearly single. All appear to be cluster blooming and many seem to have inherited much of the growth habit of 'Home Run', which I'm not altogether pleased with. (I find 'Home Run' to be a rather homely shrub as regards its architecture)
Next year the best of the 141-09's will go outside into the open garden to establish for disease resistance evaluation. This is a high priority matter with this group of seedlings, as I am determined to develop my own line of shrubs that carries near 100% immunity to "the big three" fungal diseases. We can hope, anyway.....
Friday, September 3, 2010
And so, I grew a population of open pollinated seed to see what traits it had to offer. Mostly, I expected to see a range of characteristics, both dominants and recessives, but I didn't expect to keep any of the seedlings. The one pictured here was most noteworthy, with its well-formed blooms, spotless foliage, dense, bushy growth habit and balanced scale of all plant parts (tiny). It didn't hurt that the blooms are remarkably sweet-scented for such tiny flowers. (Blooms do not exceed 0.5" in diameter) So, I'm keeping this feller. I've struck a few cuttings already and it roots in a matter of days (+- 8 days), which is even better.
Funny, isn't it, how these little gifts turn up in a body of work in the places you don't expect them. The surprise factor is probably what I enjoy most about the work I do. I imagine a lot of hybridizers feel the same way. :-) Oh, and one more thing: I have given it a nickname for now; a reference to a rose it resembles: 'Si', by Pedro Dot. I'm calling it "Si Plus Plus". I wonder how many people will get that pun?
Thursday, August 26, 2010
The seedling's foliage is fragrant when touched, giving off a combined scent of Frankincense and Raspberries! It is pretty clear that this one is going to be vigorous and a semi-climbing plant, whereas its sibling more closely resembles its R. foliolosa parent, remaining more shrubby. No flowers yet, but then I don't expect to see any till next Spring. There is always the possibility that this cross (I have two seedlings, this is just one) will not have fertility to breed another generation, but I have a hunch it will be. I have another hybrid that is a diploid breeder (42-03-02) out of Moore's 0-47-19 (R. wichurana X 'Floradora'), crossed with an R. rugosa hybrid, which will have the ability to pass on remontancy while remaining a diploid. I'm trying to avoid getting into triploid territory for now, just to make things easier to deal with.
I will post photos of the 42-03-02 X R. rugosa seedling soon. It shows considerable Rugosa influence in its foliage.

Click on the image for a much larger view.
This is a Kordesii hybrid and as such, it may exhibit both superior Winter hardiness and disease resistance. It's still very young, and only recently transitioned out into the garden, so these aspects of its nature are yet to be determined. In the meantime, I am going to admire its wonderful color (no photo I take does its hue justice: it is a much richer, more vibrant purple/magenta than it appears here) I have learned that it is remarkably easy to propagate as well, something many modern roses sorely lack.
Friday, August 13, 2010
The seed parent, 42-03-02, is a selfing of Ralph Moore's Wichurana breeder 0-47-19, presumably also a diploid. I have used this plant in breeding a few times in years past with mixed results, but I was most often crossing it with tetraploids. Now I limit myself to pairing it with other diploids. (I have seedlings from it using 'Therese Bugnet' as a pollen parent, to name just one)
So, what is remarkable about this seedling? The fact that it is a repeat bloomer, flowering in its first year. Normally you would not obtain any repeat bloomers from a first generation cross with a native species, but it appears this R. pisocarpa has some secrets up its sleeve! Whether the plant has any merit as a garden shrub or as a stepping stone to better hybrids is yet to be determined, but this seedling makes me hopeful.
Click on thumbnails for a larger image.
118-09-14 is still a fairly small plant in a gallon can, with canes no more than 14" long. The foliage, architecture and overall "feel" is intermediate between the two parents, but leaning a bit more towards R. pisocarpa in my opinion. The foliage has been very clean so far, but I reserve judgment until it has lived out in the test garden for a while. (With R. wichurana strongly represented in its pedigree, plus 1/2 R. pisocarpa, I'm hoping for good disease resistance) The blooms have a fairly strong powdery scent, not unlike 'Marie Pavie'.
Thursday, August 12, 2010
This shrub is an arching, large plant that appears to have much of 'William Baffin's habit, but possibly more lax. It isn't mature enough to know for sure how it will grow, but the clues are there. It is quite thorny, although the thorns are bent at the tips and not at all inclined to rip flesh, as some do. Blooms are 3" across, in clusters of five or more, about ten petals each and a clean, medium red as you can see. It is also obvious that the buds are decently mossy, a trait I expected to lose in this cross!
Now the thing is to determine how good its Blackspot resistance is. Its the first Summer out in the garden, so until it has seen a Spring, its premature to say anything about disease resistance. (Although it has been remarkably Mildew free so far, unlike most Mosses grown here)
If nothing else, this will find its way into the 2011 breeding schedule, to see what traits it passes along. It has set open pollinated seed freely and those will be germinated next Spring to evaluate the plant's potential.
Thursday, August 5, 2010
I was genuinely surprised to see these seeds germinate this Spring, and even as they grew I expected them to turn out to be selfs of L83. Now that they are a couple months old, its quite clear these are R. fedtschenkoana hybrids, with the matte bluish foliage that smells of Pine when rubbed. All three of these are remarkably intermediate in look between their parents. I can see distinct L83 qualities, and clear R. fedtschenkoana traits in all three. Of course, none of these has bloomed yet and I don't expect to see flowers until next Spring, but in terms of their pedigree, these represent potentially remarkable hybrids, unlike anything else before them.
Its curious how, after 15 years of hybridizing, I am now paying so very little attention to the flower style and color, favoring instead the development of unique and sturdier shrubs with better hardiness than their predecessors. (Click on the thumbnails for a full-sized image)
Shown here are a few images of all three plants, their overall appearance, foliage and thorns.

This is a mightily vigorous seedling, having produced new basal growths recently that have grown from zero to three feet in only three weeks. I am pleased to note two things: 1) this plant has set seed easily using a variety of pollen parents, and 2) it is repeating bloom in flushes, where in its first year it did not bloom at all. One of its siblings has proven extremely easy to propagate and I will be testing this cultivar for ease of propagation soon as well. I think this has promise as a potential link to new kinds of shrubs for the modern, low-maintenance garden.
Thursday, July 15, 2010
It is interesting to note that all of the remontant seedlings obtained from various Morden Sunrise crosses have that unusual Cinnamon/musk fragrance!
Sunday, June 27, 2010
At this point I am visualizing these selections as breeding specimens only, but who knows. Perhaps one or two of these will mature to have excellent garden-worthiness properties, in which case they may become candidates for release. I;ll post photos of some of the siblings as they mature.
This cross was made with the goals of creating a breeding stock plant that was 1) a diploid, 2) well pigmented in the red range, 3) exhibited many of the R. wichurana traits such as disease resistance, attractive foliage, abundance of bloom and ease of propagation. With any luck, some or all of these criteria will be found in this seedling, or one of its siblings.
I cannot comment on the mature growth habit of the shrub. That is to be determined in the next 24 months. I list this as a diploid seedling since both parents are confirmed diploids. It is unlikely that it is anything but a diploid.

'Marianne' = 'Duchesse de Montebello' X 'Abraham Darby'. Registered 2001. Available from Rogue Valley Roses.
Friday, June 11, 2010
Wednesday, June 9, 2010
This is one of about six selections I have now culled down to from the cross made in 2007 of ('Penny Ante' X 'Tradescant') X L83. The seed parent is a proprietary hybrid of mine that I often use for breeding to get both good color and vigor into my work. It turns out to have been an excellent choice with which to mate L83, the AgCan Kordesii breeder.
Seedling #77-07-12 is my favorite of this group, with its heavy, dark glossy foliage and the 4" double red and purple blooms, reminiscent of a slightly less double 'Charles de Mills'. It has a modest "modern rose" fragrance that is neither strong nor remarkable, but pleasant just the same. The foliage has so far been completely immune to Blackspot, whereas other seedlings immediately next to it have lost 80% or more of their foliage to the disease. While I am considering this as a "finished" variety (IE: headed for market) I am also working on proceeding with it as a breeder, crossing it with its siblings and one of the yellow L83 hybrids, the idea being to improve further on the excellent disease resistance of these L83 seedlings.

Anyway, lets look at this example. This is 'Westerland' X 'A Shropshire Lad', the latter being one of the more recent Austin roses, which, like 'Westerland' is a large shrub that can be trained as a "climber". (I put that in double quotes because, like so many similar modern shrubs of a certain stature, this rose is often referred to as a "climber" when in fact it is nothing at all like the true climbers: the Ramblers, Hybrid Multifloras and others bred from true climbing species. Of course, it can be argued that no rose is a climber in the true sense, as they have no tendrils or tools to grasp with. They are simply "opportunistic climbers", relying on chance that their prickles will latch onto something supporting as they grow towards the light.)
I saved this seedling at the last moment, only because it had such excellent foliage and a glimmer of pleasant color. I almost culled it because in the first two seasons the blooms were less full than I would have liked. This Spring, however, the blooms are reasonably full and quite attractive. (Certainly more petals than previously) It is showing excellent vigor as well, and appears to have excellent resistance to disease (so far). The fully expanded bloom shown here is about 4" in diameter. Larger canes are blooming in clusters of three to five, while laterals often have only one or two. Half open buds are yellow brushed heavily with flame, expanding to more of a "Peace yellow" with splashes of pink and red at the petal edges. Yes, it has a pleasant scent, though not intense. I'll be watching this one more closely now, I think ;-)
So, in case you were considering using 'Westerland' as a breeder, I would say yes, go ahead and see what it can do for you. It might not do exactly what you want, but I believe it is worth exploring.
Sunday, May 30, 2010
I obtained only four seedlings from this cross and unfortunately, all have been *ahem* a tad weak in the vigor department. Mind you, that isn't going to prevent me from using this selection in breeding. I can always abandon this avenue should the offspring turn out to be wusses: nothing ventured, etc, etc. It does, however, have a rich and complex "wild rose" fragrance that can undoubtedly be capitalized upon. I'd be interested in crossing this with 'Therese Bugnet' except that TB is a diploid, so I'll leave that out of the equation for now. I may, however, turn to the Hybrid Spinosissima 'Suzanne', which has been reported as being a tetraploid. For now, recovering remontancy without sacrificing disease immunity is paramount; color, my friends, will have to wait ;-)
Saturday, May 29, 2010
From the 2007 crosses I made, two groups stand out as having at least two or three selections that show both extremely good Blackspot resistance (near immunity) and apparent Winter hardiness (based on my limited experience). It should also be noted that several selections have good to excellent color and attractive bloom form. All have excellent vigor and attractive foliage. About 5 plants have been kept from the cross of ('Penny Ante' X 'Tradescant') X L83, including the fire engine red 77-07-23, which was used to a limited degree in 2009 breeding.
Illustrated here is the best yellow selection from 'Golden Angel' X L83, numbered 04-07-05. Some of you have probably noted that this is a cross of a triploid X a tetraploid, and so it is possible that the 04-07 selections are a mix of triploids and tetraploids. Some of these set open pollinated seeds last year (which I allowed to happen in order to determine fertility) and seeds were saved and a percentage have germinated. I am now starting to put select pollens on this yellow cultivar with the hope of moving forward with a Kordesii derived yellow breeding line. There is certainly a lot of room for improvements in both Winter hardiness and disease resistance in yellows! For now, I am limiting myself to using other first generation L83 hybrids to breed with this selection, and in fact will be crossing most of my best L83 selections with each other this year. Most are strong reds and medium yellows, so color results should be bright and rich with any luck.

It is a fairly well documented fact (R. S. Moore and others) that the miniaturism trait is a dominant one, and you need only one of the parents to be a miniature in order to obtain a good percentage of dwarf plants from a cross. Well, what happens if you cross miniature X miniature? Often, the offspring get smaller still! If you have ever done a cross like that, you will have no difficulty imagining how Pedro Dot came up with 'Si'.
Illustrated here is one of the first seedlings to bloom from a crop of 'Magic Wand' X self seeds. Out of about 80 seedlings I have grown, I would say that about 90% are dwarf, with about 25% of these being extremely dwarf. About eight or ten seedlings appear to be much larger in both leaf and growth habit than the parent variety, which is also to be expected with such crosses.
To give you an idea of scale (yes, I ought to have photographed it with a coin beside it) the pot shown here is 2.75" square. The plant is currently no more than 1.5" tall, and I would estimate that bud is no more than 1/8th of an inch tall (center of the plant, pale pink): the ultimate in cute. Click on the photo to get a much larger image.
I didn't grow this group of seedlings with the idea of actually keeping any of the offspring, I did it to show me the scope of what 'Magic Wand' would do as a parent. If it harbors extremely undesirable traits, they will show up in a selfing batch. Desirable traits as well, will manifest in the seedlings, and so this is a learning excercise more than anything. I often sow self-seedlings from a variety before I put it into actual use as a breeder, just to determine its fertility and other traits. Mind you, I am pretty certain that I will save a few of the best of these tiny things and keep them around as curiosities. ;-) I'll post photos of some of the others as they flower, assuming they are the least bit photogenic!

This is the first of a group of 'Midnight Blue' X L83 seedlings to flower, last year's crop of seedlings. L83 seedlings rarely flower in their first year, undoubtedly a trait carried over from its R. rugosa ancestry. This is a particularly richly colored flower and I am picturing a 4 X 4 foot shrub at maturity, loaded with hundreds of these intense magenta-purple flowers. If it repeats decently, this just might be worth space as a garden shrub! (as opposed to being used strictly for breeding, which is how I see it at the moment)

Yesterday I posted a photo of the first bloom of one of my 54-08 hybrids (Midnight Blue X [Orangeade X R. fedtschenkoana]). Today, two more opened their first blooms, and one of these, 54-08-01, is pretty spectacular: deep fuchsia/purple blooms about 2" across, with 15 petals and a modest fragrance. The plant is nearly identical to all of its siblings in most ways, showing heavy influence of R. fedtschenkoana: small, fern-like cedar-scented foliage, upright growth and plenty of needle-like prickles. There is a tiny bit more info available on the HMF page for this seedling.
I have gathered the pollen from the two blooms shown here and hope to use it tomorrow. I have to ruminate a bit to select an appropriate parent from what is in bloom right now. Perhaps 'Little Darling'??! (just kidding!)
