30-36" x 15" wide (seed propagated) This is a very rare native wildflower found only in the Ozark region of Arkansas and Missouri. The paradox of this plant is that it is a "yellow" purple Coneflower! The foliage is long and narrow, the golden-yellow flowers are good sized and showy. This is a tap-rooted plant that requires several growing seasons to reach its full size, so be patient. Because Ozark Coneflower is a somewhat lanky grower, I recommend that you plant them in groups of 3 or more to maximize their impact in the garden. Zones 4-9.
