Improved Snowball Y Cauliflower Seeds – Heirloom Self-Blanching Variety | Dense, Bright White Heads Since 1884
Minimum: 50+ Seeds
Most cauliflower needs help getting white. This one does it by itself.
That single fact — self-blanching — is what made Snowball Y one of the most trusted cauliflower varieties in American home gardens and market farms for over a century, and what keeps growers coming back to it year after year. Blanching is the process of protecting a developing cauliflower head from sunlight, which causes it to turn yellow, green, or purple instead of the pristine white most growers are after. Traditionally this meant going into the garden by hand and tying the outer leaves over the head — a tedious, time-sensitive task that required checking every plant individually as the heads matured. Snowball Y does this on its own. As the head develops, the plant's long outer leaves curl inward and wrap naturally around the curd, shielding it from light without any intervention from the grower. The result is that characteristically bright, dense, snow-white head that gave this variety its name — reliably, every time, without the labor.
The history: The original Snowball cauliflower is documented as far back as 1884 — one of the older continuously-grown cauliflower varieties in American horticulture. Snowball Y Improved was introduced by Ferry-Morse Seed Company in 1947 as a selected, more vigorous strain developed from those original Snowball lines, bred for greater uniformity, stronger head formation, and better adaptation to shorter growing seasons in northern and cooler climates. It has been in continuous cultivation ever since — a variety that has outlasted dozens of newer introductions simply because it works, consistently and beautifully, in a wide range of gardens and climates.
The plant and the head: Snowball Y Improved grows as a compact, sturdy plant reaching 18 to 24 inches tall — manageable in raised beds, garden rows, and smaller plots without the sprawling habit of larger brassicas. The heads mature at 6 to 8 inches across, dense and tightly packed with fine, smooth curds in a pure, bright white. The flavor is mild, gently nutty, and faintly sweet — the kind of clean, honest cauliflower flavor that roasting intensifies beautifully and that holds up equally well raw, steamed, or cooked into soups and gratins. Heads weigh one to two pounds at peak maturity and hold well in the field, giving you some flexibility in harvest timing without the curd opening or yellowing rapidly. Matures in approximately 70 to 80 days from transplant.
Cauliflower is one of the more rewarding but demanding vegetables in the garden — it wants rich, fertile soil, consistent moisture, and cool temperatures to develop properly. Give it those things and Snowball Y will deliver one of the most satisfying harvests a kitchen gardener can pull from the ground.

Growing notes: Start indoors 8 to 12 weeks before last frost in peat pots to minimize root disturbance at transplanting. Sow a quarter inch deep at soil temperatures of 65 to 75°F. Cauliflower is a cool-season crop — transplant outdoors in early spring for a summer harvest or in midsummer for a fall harvest, which many growers find produces the best heads. Full sun, well-drained, fertile soil with a pH of 6.0 to 7.0, and consistent moisture are non-negotiable for good head development. Side-dress with a balanced fertilizer every three to four weeks. Space plants 18 to 24 inches apart in rows 24 to 36 inches apart. Harvest when heads are fully formed and firm — cut with a knife, leaving a ring of outer leaves around the head to protect it during storage.
Heirloom. Self-blanching. Snow-white. A variety that has been quietly earning its place in the garden for over 140 years.
