Recently I take this picture form a Private Garden here in Santiago, Chile. Did somebody know what species it is?
try this link for the plant Chris suggested, I think after looking at the pictures that we may stil have some further checking to do.. (no offense Chris :) http://hortiplex.gardenweb.com/plants/p1/gw1010896.html
Thanks Paul....... We have grown a plant identical to the one shown for about 15 years. The tubers came from a reputable Dutch nursery labeled C. coelestis, and it now appears they may have been mislabeled. I'm not the only one who may be wrong: this German site shows a plant similar to the one in question. See this page on the United States Department of Agriculture web site also Perhaps it is C. communis; then again, C. erecta is known to be a polynorphic species with many named variants. I will have to wait until it's in bloom this summer to try and positively identify our plant.
