Plant Description

Prairie dock has nearly leafless, 10’ tall flower stems with bright yellow, sunflower-like flowers in late summer/early fall.  Its strong stems are held well above big, coarse clumps of basal, very large (up to 2’ long), sand paper textured leaves. Prairie dock occurs naturally in limey soils of woodland borders and old fields from central Canada down through central and southeastern United States. It is tall, stately, easy, and very drought tolerant once established. Finches will love the seeds; all sorts of bees and butterflies will love the flowers; and rabbits and deer will leave it alone. Add some tall grasses, some wild indigos and coneflowers for earlier flowers, then stand back and admire!  New this year!
