This "hobby" (for surely that is what I must call it since it doesn't pay for itself; it is a drain on my resources, both monetary and emotional) has reached a scale that is unmanageable and so I have to look very hard at what there is here and be ruthless in removing anything that does not approach perfection. (and since perfection is so very conspicuous by its absence from most roses, that ought to be easy enough) With any luck, this approach will reduce the volume of plants, and the associated work load, to a fraction of its current state. Then, and only then, will I consider resuming the making of new crosses and raising more seedlings. I may not resume at all. Only time will tell.
As regards this blog; I make no promises that I will continue to post information. I will if the mood hits me, but for the most part I will focus my energy on the work at hand: reducing my work load and hard culling of materials. Wish me luck. And thanks for reading and contributing to this blog for the past two years. It has been a pleasure engaging my readers.

This was a huge surprise, color wise. I selected 'Midnight Blue' knowing that if anything could add color to a cross that might bleach out to pale pinks or peaches using most any other parent, 'Midnight Blue' could. I guess I wasn't wrong! This is the second selection that has bloomed in a very dark color. Much darker than anything I imagined possible. I wonder if it has anything to do with the fact that R. soulieana is represented on both sides of the parentage equation? Hmmm.
Bloom form is a bit disorganized, but that might right itself in time. It is already forming the next blooms just as the first is opening, and lots of new growth is appearing from the base, indicating a potentially shrubby, compact habit. Oh, and yes....it has a fragrance too. Fun, eh wot?

This is a strikingly pretty red single, presumably a diploid, selected for further breeding. It appears very eager to set seed and hopefully I will start to see repeaters in the next gen. Very healthy plant! This is making me very pleased to have started over at the species level.

Anyone interested in R. wichurana seedlings?! ;-)

The foliage, as I have noted in a post last year, is fragrant: somewhat like Raspberry and Pine combined. The plant has been immune to mildew and I would expect it to be similarly resistant to blackspot. (I won't know till later this year) The blooms, while unremarkable, are already being borne in large clusters on this 2 foot tall arching plant. Some panicles have over a dozen buds. Not surprising, given the parentage, the color is a soft "apple blossom pink" hue, and there is a modest scent.
For me, this is far from being a "finished" rose, but represents an avenue to make new hybrids that might escape many of the pitfalls all too easily inheritable from the standard Hybrid Tea/Floribunda class that currently dominate the marketplace. I think that the new garden shrub roses are going to have to be nearly indestructible compared to their predecessors; easy shrubs that provide four season interest. (interesting canes and architecture in winter, lots of bloom in the spring/summer, and colorful fall foliage, perhaps with bright hips as well) This seedling has already shown itself capable of providing colorful fall foliage, as have many of my R. foliolosa hybrids. Perhaps integration with Rugosa hybrids like 'Will Alderman' or 'Therese Bugnet' and repeat bloom will be reintroduced as well. I will also make crosses with David Zlesak's lovely red diploid 'Candy Oh Vivid Red', which has shown itself capable of breeding good rich reds when crossed with other diploids. (David's rose is also remarkably winter hardy and disease free in most climates. Well done David!)
Once there are more blooms of 87-09-01 open I might offer pollen to my colleagues, if interested. R. soulieana imparts great health, vigor and beauty to its offspring and this could be of value to other hybridizers.
Seedling 87-09-02, while seemingly as healthy and vigorous as 01 last year, has not been as nonchalant about our long, cold spring; its foliage has been "troubled" and the first round yellowed and dropped off. A sign of something I don't want to bring into a breeding line? Perhaps. I will watch it as the season develops. Many roses I grow here struggle to produce normal foliage until the weather settles into a warming trend.

I've often pondered Ralph Moore's work with the Rugosas. 'Rugosa Magnifica' (van Fleet) was once Ralph used often, as well as 'Belle Poitvine' and various selections of R. rugosa rubra. I am aware that Ralph often disregarded ploidy when choosing what crosses to make and I have come to feel that there are definitely occasions when matching ploidy is potentially beneficial. For instance, this year I am flowering out a group of diploid hybrids made with 'Therese Bugnet', most of which involve R. foliolosa or one of its hybrids. These were created with attention to matching diploid-to-diploid. More on these in a coming update.
One of the lucky choices I made was in selecting a self-pollinated seedling from 0-47-19 (Moore, 1947: R. wichurana X 'Floradora'), code number 42-03-02. I am presuming (and undoubtedly correctly so) that it is a diploid, like its parent. So, making the same assumption about 'Rugosa Magnifica', I put the latter's pollen on 42-03-02 in 2009. I got only two seedlings, both growing like dwarf Rugosas, with Rugosa character in every way. Neither flowered in 2010, both are in bloom right now. The second seedling, 106-09-02, isn't quite "right"; the blooms are like miniatures of the Rugosa pollen parent, but very muddled in form, not opening correctly at times. The one I do like is 106-09-01 pictured here. The photo barely conveys its luminous purple-magenta coloring and the shimmery texture of the petals. The blooms are not large; about 1.5 to 2.0" across. Every one has been a simple five-petaled bloom and there is plenty of pollen available. (Needless to say I am using the pollen on a wide variety of other diploids and more)
I hope this little shrub (it is still only 15" by 15") will grow up to be something pretty, because I think a 3 by 3 foot mature specimen loaded with flushes of these richly colored blooms would be remarkable. With its parentage, I would expect superior disease resistance as well. We'll see!
