Pediomelum tenuiflorum aka Pediomelum Tenuiflorum

Pediomelum tenuiflorum belongs to the pea family, Fabaceae. It is a perennial, so it lives for several years. Its names include slender scurfy pea and slimflower scurfpea. Sources also call it Psoralea tenuiflora and Psoralidium tenuiflorum. It is native to the west-central and east-central United States. Its range extends into northern Mexico. It grows in temperate regions with dry prairies and open woods. It also grows on rocky banks in its native range. It is not native to Britain or Ireland.

Plants For A Future gives a height of about 3.3 feet [1 metre]. Chicago Botanic Garden says the plant has a creeping form. Neither account gives its spread when full grown. The sources give no facts about its leaves or stems. Chicago lists blue or purple blooms from May through October. Each flower has both male and female organs. Plants For A Future says insects pollinate the flowers. The accounts give no facts about its fruit or seeds.

This plant needs full sun and does not grow in shade. Chicago lists dry soil and USDA hardiness zones 4–9. Plants For A Future says it tolerates moist soil too. It lists sand, loam, and clay as suitable soil types. The stated pH range goes from mildly acid to mildly alkaline. That source says its hardiness in Britain is still unclear. This holds true despite the plant's native range. Much of its broader care advice covers the whole genus. Those notes do not show this species' exact needs.

Plants For A Future lists beds and sunny woodland edges as sites. The long bloom season brings blue or purple garden color. The plant can fix nitrogen and hold soil in place. Reports of this soil-binding use come from its native habitat. Root damage poses a risk when moving plants already in place. Plants For A Future says such moves can kill them. It says attempts to divide plants have little chance of success. Its records do not flag a risk of weed spread.

Plants For A Future lists roots as food, raw or cooked. It also notes dried root flour for soups and bread. Yet another cited account says the roots have no tubers. These food records do not show that eating it is safe. The same source reports that it has poisoned livestock. Its skin sensitivity warning concerns related plants. It does not confirm such effects in this species. It lists no known use as medicine.
