Is Cauliflower An Annual Or Perennial?

Are cauliflowers annual?

As desired for food, the terminal cluster forms a firm, succulent “curd,” or head, that is an immature inflorescence (cluster of flowers).

Does cauliflower keep producing?

The plant continues to produce small florets after the main head is chopped off. To cut these off, use a sharp knife and make a slice 1–3 in (2.5–7.6 cm) from the top of the florets. Shoots start to grow where you made your main cut, and after 2-4 weeks you may find additional cauliflower to harvest.
