Purple Prairie Clover

Purple prairie clover (Petalostemum purpureum) is a great plant that I seldom see in gardens but should. It is a tough little plant tolerant of various conditions. It blooms for up to two months and then has interesting seed heads. Perhaps it is the huge taproot the plant produces, making it hard to transplant. The root can grow 5 feet long. But more likely it is the fact that rabbits are particually fond of the plant's foliage.
