Thanks naoki and Eron. Good info and food for thought. I'll pass this along to my friend.
Eron, I've had my cernua for about 25 years. I also had 2 other clones; but, they died in recent years as I've been keeping my greenhouse cooler in the winter to save cost and this species does NOT like that. The clone I have left, 'Charlie', also had rot issues in each of the last 3 or 4 winters. I was too slow to recognise what the problem was before the other two clones were gone. Anyway, all 3 clones always bloomed for me in the fall, never have I had any cernua flowers at any other time. This new species is interesting (thanks for the link naoki) and the fact that you, Eron, get cernua blooms in the spring is also interesting to note. I guess ALL the cernuas have not read the books!
