We promise to provide you with high-quality, fresh and viable flower seeds.

Bullet Points:

• The "Frost-Sweetened" Magic: Bitter store-bought sprouts are a thing of the past! Our seeds produce sprouts that only reach peak perfection after a heavy freeze, turning crisp bitterness into a wonderfully sweet, buttery-nutty flavor.
  
• Stunning Garden Spectacle: Watching these towering 2-to-3-foot stalks—lined with perfectly uniform, tight green spheres—become heavy with frost is one of the most rewarding sights in a winter vegetable patch.
  
• Incredible High Yield: A single, healthy stalk can produce 50 to 100 sprouts! Plant just 2 or 3 seeds, and you’ll have enough for multiple gourmet holiday side dishess.
  
• Winter Gardening Champion: Built to laugh at snow, ice, and freezing temperatures. This crop extends your gardening season well into the dark, cold months when most other plants have perished.
  
• Gourmet Culinary Star: Roast them until caramelized with balsamic glaze and bacon, or shave them raw into a winter slaw—they are a chef’s favorite for elevated holiday meals.
  
• Nutrient-Dense Superfood: An excellent source of immune-boosting vitamins C and K, plus fiber and antioxidants. A healthy indulgence for your family.
  

Product Details:

• Genus: Brassica
• Species: Brassica oleracea (Gemmifera Group)
  
• Hardiness Zone: USDA Zones 4 – 11 (Exceptionally cold-hardy; survives down to 20°F and light snow).
  
• Days to Maturity: 90 - 110 days (from transplanting).
  
• Days to Germination: 5 to 10 days (Optimal soil temp: 65°F - 75°F).
  
• Seeding Depth: ½ inch (1.2 cm).
  
• Row Spacing: 24 - 36 inches (60 - 90 cm).
  
• Plant Height: 24 – 36 inches (60 - 90 cm) tall upright stalks..
  
• Growth Habit: Tall, single-stalk upright plant. Produces dozens of tight, miniature cabbages (sprouts) along the thick axil of the main stalk. Lower leaves drop naturally as the sprouts mature.
  
• Soil Preference: Deep, extremely rich, loose, moisture-retentive loam heavily amended with organic matter. pH 6.0 – 7.5.
  
• Temperature Preference: Cool weather. Best performance at 55°F - 65°F (12°C - 18°C). Tolerates heavy frosts and snow. Will fail if temperatures consistently exceed 75°F during early growth.
  
• Light Preference: Full Sun (minimum 6-8 hours of direct sunlight).

How to Plant & Grow:

• Site Preparation: These are heavy, long-season feeders! Choose a spot with full sun (6-8 hours). Prepare deep, incredibly fertile soil by working 4 to 6 inches of aged compost into the top 10 inches of the bed. They need a strong foundation to grow tall.
  
• Sowing: Because they take 3-4 months to mature, timing is critical. Do not plant them in spring for a summer harvest; they will bolt and turn bitter.Start seeds indoors 4-6 weeks before your target transplant date, or direct sow. Plant seeds ½ inch (1.2 cm) deep and keep the soil consistently moist until germination (5-10 days).
  

Spacing:

• For Strong, Tall Stalks: Space plants 18 to 24 inches (45-60 cm) apart in rows spaced 24 to 36 inches (60-90 cm) apart. They need plenty of elbow room..
  
• Square Foot Gardening: Plant 1 plant per 1-square-foot area.
  
• Watering: Consistent, deep watering is vital through the long growing season. Give them 1.5 inches (4 cm) of water per week. Apply a thick layer of organic mulch (straw or wood chips) around the base to keep the roots cool and preserve moisture.
  
• Gardener’s Pro-Tip: About 3 to 4 weeks before your first expected frost, pinch off the leafy rosette at the very top of the plant. This "topping" technique directs all the plant’s energy into plumping up and fattening the sprouts along the stalk.
• Harvesting: Wait until after the first heavy autumn frost in your area.Harvest from the bottom of the stalk upwards (lower sprouts mature first). Twist and snap them off, or cut them with a small knife.
  
• Pro-tip: You can also cut the entire tall stalk at the base, bring it inside, and strip the sprouts off comfortably at your kitchen counter—a stunning centerpiece for holiday meals!
