It has been mentioned that the name Colchicum parnassicum is misapplied in cultivation to C. laetum hort. However, the Archibalds offer seed of a documented collection of C. parnassicum, which I am growing though it is not mature enough to flower yet, so in spite of being misapplied in gardens it is apparently a valid name -- at least at some point in the unsatisfactory nomenclature of this genus. I just inventoried my bulbs and find I have about 120 accessions of Colchicum, but these include some hybrids and some as yet unidentified ones grown from wild-collected seed, as well as multiple wild sources for the same species, so in this collection there are probably about 70 actual distinct species as now recognized, not counting the named horticultural selections. If I had to pick just two for a desert-island garden, I think the big one would be C. speciosum 'Album' and the small one C. cupanii ssp. bertolonii. Jane McGary Northwestern Oregon, USA
