Cold-hardy mini broccoli with deep purple florets on narrow stems and very strong, upright plants. For late summer or early fall planting to overwinter and harvest in early spring. 3-week harvest window. Later maturity prevents floret damage from early spring frosts. NOTE: Vernalization (prolonged exposure to cold temperatures) is required for a successful crop. Bonarda will winterkill if unprotected and temperatures fall below 20°F (-7°C).
