Seemannia (aka Gloxinia) sylvatica clones?
For several years I've been growing a clone of Seemannia sylvatica which has perennialized in my borders; unfortunately it waits until December to begin blooming, by which time we've usually had a killing frost. At the NC state farmer's market last week I purchased another plant which appears identical, except that it's in full bloom now. Is anyone aware of clonal differences within this species that would cause this behavior? Another possibility is that the growers may have manipulated the daylength in order to produce bloom - the person selling the plants didn't seem to know much about them.
