Michael, I don't know which climate area you are in, but you can still plant out cauliflower seedlings during colder weather. In tubs, protected from frost they should grow well. They will spread their leaves to about 1 1/2 x 2 feet (40x60cm),bigger leaves mean better sized curds.

Annie, the curd keeps growing for quite a while but it is best picked while still white and firm. Each plant will grow at a different rate so they won't all be ready together.

The cauliflower curd is edible if it is slightly yellowed. It will have a stronger flavour, not always acceptable. Sunlight causes discolouration and this is worse in warmer climates.

Cauliflowers can take 4 to 6 months to grow to a usable size, so hang in there.
