Tall coneflower grows to 3–5’ in cultivation, 9–10’ in the wild. Ideal for low maintenance native and cottage gardens. Blooms continually when cutback, one of the last flowers to bloom. Forms a clump and requires little weeding once established. We have found laciniata to grow on the taller side if it receives regular water on a timer. Handles wind but not Maritime exposure. Edible young stems eaten like celery. Tea made from the root mixed with Caulophyllum thalictroides, blue cohosh, is used to treat indigestion. Also known as goldenglow, green-headed coneflower, tall coneflower and thimbleweed. Several other plant species are also known as thimbleweed.
