Description: Parsnipflower buckwheat is a perennial forb to subshrub with a branching woody stem. Leaves are covered with dense white hairs making the herbage appear a light green to blue-grayish color. The flowers are a creamy-yellow color and have six petals which are borne in simple or compound umbels. Plants of parsnipflower buckwheat can be distinguished from other closely related members of the genus by having a whorl of 5 to 10 leaves at midpoint of flowering stem; however in some subspecies this is not apparent (Freeman and Reveal 2005). The seeds, or achenes, are light to dark brown from 3 to 5 mm long. There are approximately 374,000 seeds/kg (170,000 seeds/lb).
