In Zone 12a you can estimate when you can plant cauliflower by checking out the USDA zone info.

The last month that you can plant cauliflower and expect a good harvest is probably November. If you wait any later than that and your cauliflower may not have a chance to fully mature. Starting your cauliflower indoors is a great way to get them started a little bit earlier.
