|'Crown of Rays' is an easy to grow upright, clumping perennial, which does best in average soil (not too fertile) and full sun. Leaves are narrow and lance-shaped. Mid- to late summer flowers are golden yellow, held in flattened panicles, resembling a golden crown. Grows to 24" tall and spreads 18". Contrary to popular belief, goldenrod does not cause sinus problems, rather another, less noticeable plant (ragweed) that blooms at the same time, is the culprit. Great with black-eyed susan, mexican sage or other salvias, autumn joy sedum and pennisetum.
