Lomatium quintuplex
Umtanum desertparsley is a small perennial herb in the carrot family, native only to a narrow area of central Washington's scablands. It thrives in shallow, rocky, dry soil over basalt and is best suited to dry-climate gardens that mimic its native conditions.
Lomatium quintuplex is a perennial herb in the carrot family Apiaceae, native to the U.S. state of Washington, and known by the common name Umtanum desertparsley. It grows in thin rocky soil on open slopes and is known only from a small region in Kittitas and Yakima counties.
Lomatium quintuplex has a narrow range in central Washington scablands, but it can be locally very common. It generally grows in shallow rocky soil above basalt bedrock, where water comes mostly from snow melt and early spring rains, and the soils are often dry to bedrock by early summer.
