3200 - Arugula, this spicy salad plant has been grown for over a century. High in protein and uniquely flavored. Deeply cut arrow-shaped leaves and white flowers are all edible. Can be planted early as it prefers cool weather.Sow every 3 weeks from mid-spring for a continuous harvest. Use floating row cover where flea beetles are a problem. Harvest either whole plants or as cut-and-come-again. Taste is sharper after flowering, and immature flower buds can also be harvested for salad green.
