I made this cross in '07 with the idea of working the lovely native R. arkansana into my work, without resorting to using modern China-derivatives in order to preserve tetraploidy. And so, I turned to an old favorite: 'Tuscany Superb'. (FYI the Gallicanae are almost all tetraploids by nature) I am particularly interested in R. arkansana because of its exceptional Winter hardiness, its complete immunity to disease and the fact that my specimen (seed grown in 1999) blooms at least three times a growing season, with long rests between flushes. Could this be a remontancy trait that can be incorporated into new species derivatives? We'll see.
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 ;-)
