30-40 days. Simple, convenient, and practical, these fresh, mixed lettuce greens can be planted just steps away from your kitchen. Our City Garden Mix is a blend of lettuce varieties combined into easy-to-handle pellets. Toss a pellet or two into a container, and you’ll have a gorgeous pot of red and green lettuces in no time. They’ll re-grow numerous times, so you can enjoy the freshest salads for several months from a single planting.
