Identification:

Sulfur buckwheat is difficult to identify as it is highly variable with over 30 recognized varieties! Their branched woody stems can form low mats or shrubs to over 2 feet tall. Their small, bright yellow flowers are clustered together in large balls, or umbels, at the tips of the leafless stems. A whorl of leaflike bracts can be seen below their flowerhead. Sulfur buckwheat flowers often change color as they age, turning reddish, sometimes cream or purple. Their small, oval leaves are found at the base of the plant, they can have white wooly hairs on their underside.
