Chenopodium quinoa 90-120 days. The gluten-free, low-glycemic seeds provide a unique, plant-based complete protein source and are especially high in the essential amino acid l-lysine. For greens, sow 1 inch apart and harvest entire plant at 6–8 inches tall. For grain production and enjoying selected leaves throughout the season, plant 12–14 inches apart. Temperatures above 90°F may inhibit seed formation, but anyone can grow it for nutritious leaves and outstanding ornamental quality. Blooms in late summer to autumn. Selected for its vivid display of colorful seed heads, this blend offers a practical and striking addition to ornamental beds, adding dazzling shades of fuchsia, burgundy, lime green, cream, orange, and yellow. Shorter-statured plants typically reach 2–4 feet at maturity. Approximately 350 seeds per ½ gram.
