It takes a LOOOOOOOOOONG time. 55 days to harvest depending on weather. And unfortunately it's a cool/cold weather crop. The heat might kill it before it gets going. I planted some late cabbage and I'm thinking between the Kale taking over the space and the summer coming it might be done for. I did cauliflower last fall and I didn't think it would ever produce. Finally got a single cauliflower out of the only one that survived. lol
