Rainbow Cauliflower Seeds - Cauliflower, 20 seeds

Quantity: 20 Seeds / pack

Rainbow Cauliflower (Brassica oleracea var. botrytis) is a cool-season annual vegetable grown for heads in a rainbow of colors — purple, orange, green and white curds that brighten the garden and the plate. The colored heads are used just like classic cauliflower: steamed, roasted, or eaten raw. A fun, eye-catching crop for spring and fall gardens.

• Soil: Rich, fertile soil; mix in compost or organic matter before planting
• Sunlight: Full sun
• Watering: Keep consistently moist; any interruption in growth can cause small “button” heads
