Silphium laciniatum

Compass Plant

A Plants of Merit winner, this tall sturdy plant with deeply cut basal leaves adds form and texture to the landscape. The leaves resemble pinoak. In summer, large yellow sunflower-like flowers bloom on stiff spikes nine feet tall. The common name comes from a pioneer practice of using the reliable north-south orientation of the leaves for direction on cloudy days.
