Cauliflower growing calendar
The wild ancestor of the cauliflower is a leafy canola like plant of the Brassica oleracea species. Some time in the past thousand years in southern Europe, the preference developed for eating the immature flower buds of the cabbage plants. By the 15th century, the modern vegetable we know as cauliflower had developed.
