I think I got near perfect germination on these. Cauliflower has always been challenging for me to time it out and know when to harvest. I've been learning that crops that have purple or reds in them (looking at my red lettuce varieties and purple sprouting broccoli) seem to bolt less quickly than their green counterparts in heat.

Grew these last spring and they not only look stunning but taste great!
