Description

Cauliflower Snowball (Brassica oleracea var. botrytis) is the definitive American heirloom standard, first introduced by Peter Henderson & Co. in 1888. Famous for its smooth, bright white, tight curds, it forms dense, heavy 6- to 8-inch heads wrapped in protective outer foliage. Compact and fast-growing, its inner leaves naturally curl upward to shield the developing head from sunlight, keeping it pale, tender, and sweet. With a crisp, mild, nutty flavor and zero bitterness, Snowball remains the top heirloom choice for fresh dipping, roasting, steaming, mashing, and home freezing.

Good to know

Upright outer leaves naturally wrap around developing heads to protect curds from sun-browning
Reliable, uniform maturation (~65–75 days from transplant) with smooth, heavy white heads
Excellent for freezing and processing, retaining firm texture and mild flavor after blanching

Highly sensitive to heat during curd formation—excessive summer temperatures can cause loose or buttoned heads
Like most brassicas, leaves benefit from protective floating row covers to deter cabbage loopers and flea beetles
