Cauliflower takes longer than broccoli. You may be alright though a bit early perhaps as it likes fall weather.

I don't know about your variety. Sometimes odd varieties act differently than standard kinds.

It all depends on the variety. Purple of Sicily is an extremely long season (90 day) cauliflower. It does not like hot weather. If the plant is healthy, they should head in September. If the plant gets stunted from insects, disease, or weather it may never head. Grafiiti is the earliest maturing purple cauliflower that I know ( 70 day) There are many whites thatmature in 60 days.

My cauliflower [Symphony] is about a foot tall and growing rapidly. It is a full season variety that matures in October.

Hi wayne_5 and farmerdill,

Thanks much for your responses! Heat has certainly not been a problem this year here! We have been unusually cool all summer really. Sounds like maybe I am being impatient as usual. I will wait them out and see what happens!

Thanks again!

Look down in the very center. If you don't see even a smidge of head forming and the plant is in relatively good health otherwise, then you still have a chance of a head.

I've never had a cauli plant that didn't at least "try" to form a head. Been a few duds though --- starts to head, but becuse of weather or what have you, sputtered out and left me with a 2 inch head.
