Related to spinach, it can be eaten in much the same way – raw when young and tender, and cooked as the leaves mature – cooking is recommended as with spinach and chard due to oxalic acid content. High in iron, protein, calcium, and vitamins A and B1. Easy to grow and will self seed year after year. 50 days.
