Cauliflower is a cool weather veggie which thrives in the cool temperatures of spring and fall. As mentioned, it is grown for its whitish to cream head or curd. But cauliflower naturally has a range of colors, even tending towards purple, yellow, red or blue tints. This purple color in cauliflower is caused by the presence of anthocyanin, which is exacerbated by sun exposure. It is a harmless water soluble pigment found in colorful foods such as grapes, plums, berries, red cabbage and eggplant. Certain varieties, such as ‘Snow Crown,’ have a stronger propensity for a purple color in cauliflower heads.
