Southern Giant Curled Mustard


Cold-tolerant leafy greens with a spicy flavor. Eaten raw in salads and as a cooked green. Can be grown for spring or fall harvest. Sow directly in the garden up to 4 weeks before the last expected frost and in late summer to early fall for a late-season harvest. Plant seeds ½ inch deep and space plants 6 inches apart with 18 to 24 inches between rows. Can be started indoors 4 to 6 weeks before outdoor planting time for a faster harvest. Plant every 2 weeks for an extended harvest season. Leaves are nutritious and high in iron and vitamins A and C. Tolerant of light frosts.
