Choose Your Seed Pack

Available in 100-seed and 1,000-seed packs, plus ¼ oz, 1 oz, 4 oz, and 1 lb options. Select your preferred size before ordering. Weight-based packs are sold by weight, not a guaranteed seed count. This listing is for seeds, not live plants.

When to Sow

Plan for cool-weather growth. Sow in early spring for an early-season crop or in late summer for a fall harvest, adjusting planting dates to your local climate. Hot weather can slow growth and reduce crop quality.

Planting Guide

• Sowing depth: Plant seeds ¼ inch deep.
• Row spacing: Allow approximately 2 feet between rows.
• Plant spacing: Thin seedlings to approximately 4 inches apart.
• Soil: Use fertile soil with ample moisture.

Growing and Care

Maintain consistent soil moisture to support steady growth and tender stems. Give plants room to develop by thinning crowded seedlings. Check the crop regularly as it approaches maturity rather than relying solely on a calendar date.

Harvesting for the Best Texture

Harvest when the swollen stem reaches approximately 2½ inches in diameter. Older, oversized stems can become fibrous or woody. Peel away the purple outer skin to reveal the crisp flesh, then slice or shred for fresh preparations, or add to cooked dishes.

Growing results: Harvest timing, size, and tenderness vary with temperature, moisture, and growing conditions.
