Lettuce & Mixed Greens

Lettuce grows so fast you'll be eating salads within 30 days of sowing seeds. Loose-leaf varieties like Red Sails, Oak Leaf, and mesclun mixes are cut-and-come-again crops — harvest the outer leaves and the plant keeps producing. They grow in partial shade, don't need deep soil, and work brilliantly in window boxes and shallow containers. Succession-plant every two weeks and you'll have fresh salad greens from spring through fall.
