Who doesn't love a hardy volunteer? A hardy volunteer is an annual that reseeds itself in the garden each year making almost like a perennial. To encourage hardy volunteers, allow the flowers to die back and form seed heads. Once mature, shake them over the area to be reseeded, or just leave them alone and they’ll fall to the ground. In the spring, identify the seedlings so you don’t pull them up as weeds, and avoid smothering them with a heavy layer of mulch. For more gardening advice like this
