All of the above. Cauliflower in a warm sunny climate ( I don't know the climate in your part of New Zealand) has to be tied up to prevent direct exposure to the sun. When exposed they tend to green and with with some cultivars get a purple tinge. Once the heads form they go bad very fast. Here, they must be picked within 3-4 days of first show, I normally tie my mine up when the first button the size of a coin appears and start cutting three days later when the heads are 6- 8 inches in diameter. Once the curds start to seperate and get ricey they are over the hill.
