An improved selection of the classic Snowball cauliflower — itself a staple of kitchen gardens since the late 1800s — Snowball Y Improved was developed to deliver more uniform, dome-shaped heads with better heat tolerance and a wider planting window than its predecessors. The “Y” designation marks it as a superior strain selected for consistent performance, and “Improved” reflects decades of careful open-pollinated selection that made it more reliable across diverse growing conditions. For generations, home gardeners have turned to Snowball Y Improved for its dependable yields of brilliant white, tightly packed curds. Open-pollinated and non-GMO, it remains the gold standard heirloom cauliflower.\u003c\/p\u003e\u003ch2\u003ePlant Profile\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDays to Maturity:\u003c\/strong\u003e 68–75 days (from transplant)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size:\u003c\/strong\u003e Medium to large, dome-shaped pure white heads 6–8 inches across\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Color:\u003c\/strong\u003e Pure bright white with tightly packed, smooth curds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Open-pollinated, non-GMO heirloom\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFlavor Profile\u003c\/h2\u003e\u003cp\u003eSnowball Y Improved delivers the quintessential cauliflower flavor — mild, clean, and slightly nutty with a tender, fine-grained texture that holds up beautifully whether eaten raw, roasted, steamed, or mashed. The pure white curds are dense and smooth with a satisfying crunch when fresh and a rich, buttery sweetness when roasted at high heat. This is the cauliflower that defines what cauliflower should taste like — classic, versatile, and deeply satisfying from garden to table.\u003c\/p\u003e\u003ch2\u003eGrowth Type \u0026amp; Harvest Yields\u003c\/h2\u003e\u003cp\u003eSnowball Y Improved is a vigorous, upright cool-season crop that produces one large, dome-shaped head per plant over a 68–75 day period from transplant. Its improved heat tolerance gives it a wider planting window than many cauliflower varieties, making it more forgiving for spring plantings that may encounter warm spells. Each plant yields one beautiful head — plant generously for a full harvest. The compact, uniform growth habit makes it well-suited to raised beds and intensive planting.\u003c\/p\u003e\u003ch2\u003eDisease Resistance\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGood tolerance to tipburn — a common disorder in cauliflower caused by calcium deficiency during rapid growth\u003c\/li\u003e\n\u003cli\u003eBetter heat tolerance than standard Snowball varieties — more forgiving in spring plantings\u003c\/li\u003e\n\u003cli\u003eSusceptible to clubroot — rotate brassica crops annually and maintain soil pH above 6.5\u003c\/li\u003e\n\u003cli\u003eTip: Use row covers early in the season to protect against cabbage worms and flea beetles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGrowing Tips \u0026amp; Planting Dimensions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpacing: 18–24 inches between plants, rows 24–30 inches apart\u003c\/li\u003e\n\u003cli\u003eSow depth: ¼–½ inch deep indoors; transplant when seedlings are 4–6 weeks old with 4–5 true leaves\u003c\/li\u003e\n\u003cli\u003eGermination: 7–10 days at soil temps of 65–75°F\u003c\/li\u003e\n\u003cli\u003eFull sun — at least 6 hours of direct sunlight daily\u003c\/li\u003e\n\u003cli\u003ePrefers rich, consistently moist, well-drained soil with a pH of 6.5–7.0\u003c\/li\u003e\n\u003cli\u003eSide-dress with compost or balanced fertilizer at transplant and again when heads begin to form\u003c\/li\u003e\n\u003cli\u003eKeep soil evenly moist — inconsistent watering leads to hollow stems and loose curds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhen to Plant\u003c\/h2\u003e\u003cp\u003eStart indoors 6–8 weeks before your last frost date for a spring crop. Transplant outdoors 2–4 weeks before last frost when seedlings are sturdy. For a fall crop, start indoors in midsummer and transplant 8–10 weeks before your first fall frost. Cauliflower does not direct sow well outdoors — starting indoors gives you the best results.
