Well, I am doing an experiment growing broccoli for the first time but I planted the seedlings in the fall. I had read it is a cool crop so if you want to plant and live in Florida, I suggest to start now. Here is a very helpful link from UF gardeningsolutions.ifas.ufl.edu/giam/plants.../broccoli.html

I think so, it is one of our most productive garden crops. We first plant them in the fall and we are now getting a good crop. And they will continue to grow and product until it starts to get hot in May or so. We have never had bug problems.

I've never had too much success with spring planting of broccoli. Once the days stay consistently in the 80's, they tend to bolt. However, I have planted some in January, picked in early March, but the heavier crop is when I plant in late October and harvest in Dec/Jan. I am in 8b/9A zone.
