Compass Plant Silphium Laciniatum 1 Gal

Silphium laciniatum, commonly called compass plant, is a herbaceous perennial native to prairies, glades, roadsides, railroad right-of-ways, and other open, disturbed habitats in the Midwest and portions of the southern United States. A tall, sturdy, rough, bristly plant that grows on stiff, hairy, resinous stems to 9' tall. Features sunflower-like flowers (to 5" wide) with yellow rays and yellow center disks. Flowers bloom in loose spikes on the upper parts of the plant in summer. Very large, deeply pinnatifid (cut close to the midrib) basal leaves (to 18" long) are reminiscent of pin oak leaves. Upper leaves are smaller.

Good height for the rear of the border. Also excellent for naturalizing in prairies, cottage gardens, wildflower gardens or native plant gardens.
