| Cultivar Origin | "The original seed was collected at altitude in Japan where it is already accepted as one of the largest flowered gems of the race. In 1991, in one tray of seedlings, one plant developed with darker foliage which was especially notable in spring when it developed a purple rosette. Subsequent generations retained this feature, with a proportion being extremely darker leaved". (http://www.seedaholic.com/polemonium-yezoense-purple-rain.html) |
