This seedling is in line for commercial release in the next year or two, pending propagation of sufficient quantities.
Another busy morning; I need to get out and start potting up the hundreds of new seedlings into 3" pots. I am pleasantly surprised by the number of 'Belle Poitvine' hybrids I got from a cross with one of my old R. foliolosa hybrids. I need to use that thing more often, I think.

A great photo of Ralph Moore's experimental seedling "C-04", bred from 'Crested Jewel'. It was hoped to be a useful link to creating better crested Floribunda-style roses, but it was a flop as a breeder: the offspring were duds. But it remains in my collection of curious novelties where it is appreciated regularly for its unique parsley-like sepals.

Although this is an awkward grower with wiry long canes that leap out ten feet in all the wrong directions, it is a noteworthy footnote in Moore's development of the yellow and orange toned mini-mosses that followed in the subsequent forty years.
When used in breeding, Orange Moss is a difficult plant at best; it won't set seed with foreign pollen, and the offspring are often uniformly dreadful. (Ralph insisted that he never got viable seed of any kind from it, although in 2010 I germinated three open pollinated seeds from it) Indeed, it must have been that one lucky seedling in 500 that showed any promise. It is a testament to Moore that he was able to coerce this unruly once-bloomer to sire anything of value at all.
By the way, pollen will be available upon request, for those brave enough to make use of it.

It happens: seedlings get mislabeled. This one was from a batch identified as 'Old Blush' x self, which it clearly is not. Sometimes a few seeds stray into the adjacent row of another cross during sowing, and sometimes a seedling drops onto the work bench during repotting and loses its identity that way. There are numerous ways for an individual to become misidentified. Myriad are the tribulations for the hybridizer attempting to document (accurately?) his work. Alas.
Since I did a lot of work with 'Midnight Blue' in 2006, I am assuming this is one of its progeny. What the other parent might have been is up for debate. Could have been 'Tradescant', 'Dragon's Blood', 'Arthur Bell', or 'Brown Velvet'; all four were used in 2006. I could guess, but that would be pointless, since I have seen similar seedlings result from a wide variety of crosses. Ah well, its a decent individual, and has earned a spot out in the final test garden. Its all fun and games, ain't it? *laughs*

A couple of days ago I posted a photo of a bud of a 'Hansa' hybrid I had been anticipating. This is what I got:
A throwback to its species origin. Ah well. Perhaps it has a trick or two up its sleeve yet. After all, genetically it has an infusion on both sides of its ancestry of non-Rugosa genes. It might look like an ordinary R. rugosa, but what about its genotype? Maybe it will breed something more interesting. Maybe its not a lump of coal at all, maybe it is a sock after all: a sock with a purpose.

I have owned Hansa for nearly thirty-five years, and this is the first time I have used it in breeding. (Although I used a twelve year old propagation of the original plant as the seed parent) It took fifteen years of meddling with rose genetics for me to realize how much I needed to be working with the Rugosas, although I occasionally used one or other of the Hybrid Rugosas in combination with various other moderns, usually with dreadful results. (I believe the Rugosas are especially incompatible with roses descended from the China section of the family, often resulting in severe health problems. If you have ever grown Rose a Parfum de l'Hay, you will know what I mean)
So in 2009 I rethought what I was doing with Rugosas and decided to take a rather different route: I combined strongly related Hybrid Rugosas with each other, and with various diploid species. This cross was inspired by David Austin's Rugosa, Mrs. Doreen Pike, a cross of Martin Frobisher and Roseraie de l'Hay. (Don't confuse the latter with aforementioned Hybrid Rugosa I spoke of disparagingly: these two are very different animals.) essentially Austin was crossing two roses of Strong Rugosa pedigree and recovered most of the Rugosa character, while introducing a more double, elaborate bloom form. The plant has also recovered much of the Rugosa health, which is a very welcome thing.
Back to this seedling, 26-09-14: it is now about 13 months old and about to open it's first bloom. The plant itself is indistinguishable from it's species ancestors, with the same bright green, rugosa foliage and stocky, thorny growth. This seedling, and all of it's 15 siblings, are completely disease free so far, but it's early to make any long term predictions about health until the selections have spend a couple years out in the garden. Still, I sense that these are promising. The exposed petals so far indicate a typical deep Rugosa magenta hue, which isn't a bad thing, in my opinion. I am hopeful some will be more of a red color, something inheritable from Magseed. (by the way, Magseed is a sibling of Linda Campbell, from a cross of the miniature Anytime X Rugosa Magnifica, with blooms that start out a bright Cherry red and fade to more of a magenta.) I am hoping that this seedling picks up some of Anytime's fast and generous rebloom habit. At this point, I can only guess. And hope!
