17-09-02 = R. arkansana X 'Carlin's Rhythm'.I'm determined to obtain a seedling from the delicate-looking-but-unbelievably-tough R. arkansana, a North American native. The species has richly scented single candy pink blooms, and certain select clones sometimes have subtle stripes or streaks of darker color on the petals. Mine doesn't, but mine does do something I hope to capitalize on; it blooms at least three times in the growing season: late May, again in July or early Augustm then again in late September or October.
My specimen of R. arkansana is a reluctant seed setter, rarely accepting pollen from anything but itself. However, I did manage to get two seedlings from a cross using Kim Rupert's beautiful 'Carlin's Rhythm'. This is the second of the two (the first was paler and not as nice) and displays large-ish blooms (about 2.5") in a deeper than average rose pink. The scent is rich and pure "old rose". Now, the trick is to try it in breeding to see if I can make the next step. It will have one copy of the modern hybrid remontancy gene, and at least once copy of the gene that makes my arkansana repeat, which may or may not be distinct from other forms of remontancy. As both parents are (at least in principle) tetraploids, I would expect this seedling to be a tetraploid also.
