About Lomatium ambiguum (Nutt.) J.M.Coult. & Rose
Lomatium ambiguum (Nutt.) J.M.Coult. & Rose, also commonly called Wyeth biscuitroot, is a perennial herb in the Apiaceae family. It grows in dry habitats across the northwestern United States and extending into British Columbia. Its leaves are divided into many small blades. Stems may show a slight purple tint, and reach 6 to 24 centimeters in height. This species produces yellow flowers arranged in compound umbels, which bloom from late April through June. Like many other species in the Lomatium genus, Lomatium ambiguum was used by Native Americans. Dried flowers and leaves of the plant were used to add flavor to meats, stews, and salads. A tea made from these same plant parts was consumed to treat common colds and sore throats.
