Great for salads, heirloom Bloomsdale Long Standing spinach yields thick, glossy green leaves with rich, nutty flavor. The spinach plants stand a long time without "bolting," so you can harvest over a long season. Salad greens prefer cooler temperatures: sow seeds directly in the garden in early spring as soon as soil is workable. For continuous crops, resow every other week until the weather gets too warm. Quick and easy to harvest!
