I want to thank those who recommended 'Amazing' cauliflower. After many tries with many varieties both spring and fall, I have finally had success! That's amazing as is the fact that they haven't melted in this heat yet. Just to be on the safe side, earlier I pulled several leaves up over the head and clipped them together with a clothespin. Looks like it worked.
We cut the first one today and will be having it with lunch.
I can't wait to try this again in the fall when the temps are better and on a larger scale than this small trial. Woo hoo!
