General Description

Creating a large white bud head, 'White Cloud' is an excellent cauliflower variety for the cool-season vegetable garden. It has stronger tolerance to frosty temperatures in early spring and mid-autumn than other cauliflower varieties. From sowing 'White Cloud' takes 65 to 75 days to fully mature. It is a cool season vegetable that performs best when grown in the cool fall or winter, where winters are mild and frost-free.

Grown as an annual, it traces its ancestry to Brassica oleracea, a fleshy-leaved, short-lived perennial from coastal areas of western and southern Europe. When mature, it produces large, fleshy, central heads of flower buds (called "curds"), which are harvested and eaten before the flowers open. The heads are borne on thick short stalks above whorls of long leathery blue-green leaves. Cauliflower develops no side shoots, so bears only one crop. Plants perform terribly in hot weather, becoming lanky and flowering rather than remaining in bud. The smaller inner leaves tend to curl over and protect the developing curds from pests.

This cool weather crop prefers full sun and fertile, evenly moist, organic-rich garden soil with ample drainage. Cauliflower should be planted as seed or transplants in very early spring before temperatures heat up, or (ideally) in mid- to late summer for a prime fall harvest. Always harvest cauliflower heads when the curds are tight, just before they elongate and begin to loosen. It is rewarding to grow and well worth the effort. As with all members of Brassica oleracea, it remains susceptible to cabbage loopers and several other types of caterpillars that attack cabbage, broccoli, kale, and the like.
