Scabland wild buckwheat is a low, matted shrublet, from 5-10 cm tall, and sometimes several feet in diameter. The leaves are mostly linear to linear-spatulate in shape, often gray or whitish haired on both surfaces. They range from 5-20 cm long and 1.5-3 mm wide. A whorl of linear leaves may be found at about mid stem on the flower stems. No stem leaves or bracts are found directly below the flower heads.
The inflorescence is a single rounded, thumb-sized head or clump, about 13 mm across. They are a whitish-yellow color, sometimes bright lemon-yellow, or may be tinged with pink or red. The pink or red may especially be seen in the unopened flower buds (see photo below). The individual flowers are sparsely to moderately haired on the outer surface. The involucres are shallowly conical to bell-shaped with 6-10 spreading to reflexed lobes about 1.5-5 mm long, or about equal in length to the tube. .
