SILPHIUM terebinthinaceum |
||
|
Description: With leaves like small elephant ears and flowers literally as high as an elephant's eye, Prairie Dock is a truly unique plant. Masses of yellow sunflower-like blooms appear on giant stalks in late summer for a month or longer. Very long-lived, individual plants are known to flourish for decades. It thrives in clay, rich loam and damp sandy soils, in full sun. As with all silphiums, birds love the seeds. | ||||
