The day before my talk, I decided to pick any fresh-looking colchicums and take them to the talk. To my surprise I found five different varieties in good shape. Of course, it was the very last of the byzantinums, just one single blossom that I decided to pick. And since this was my first year with ‘Spartacus’, I don’t know if he will bloom so late next year. The unknown colchicum was left behind, I suspect, when I moved a clump, and it was buried deep and so bloomed late. But ‘Waterlily’ and C. autumnale ‘Alboplenum’ are usually the last to be blooming.

The talk was very well-received and I hope to give it again. If your upstate NY garden group is looking for speakers, have them contact me through GreatGardenSpeakers.com.
