Wild Arugula Certified Organic Heirloom Seeds 250 Seeds This tart and spicy, but no hot, arugula is particularly suited for container gardening. Grow arugula as you would lettuce, in the cool months. Although arugula will grow over a foot tall pick leaves often when they are small. Also like lettuce it will bolt quickly in hot weather so have it mature in the cool of Spring or Fall. Eruca vesicaria sativa
