Nice variety of Colchicum Karen!
Giant and C. cilicicum are almost finished here for the year but 'Dick Trotter' is just emerging. Its the 3rd year in the garden for DT and this will be its first bloom.
RJ, I noticed among the descriptions on Brent and Becky's website that some varieties are listed as hardy to zone 5 and others to zone 4. I wonder if you tried some that weren't quite hardy enough for your zone?
