Adenostoma sparsifolium (Redshanks or less commonly, Ribbonwood) is a multi-trunked tree or shrub in the Rosaceae (Rose) family that is native to dry inland slopes or chaparral of Southern California and northern Baja California below 6,000 ft. Shaggy falling shanks or ribbons of bark are one of the strongest characteristics of the tree, hence the common names. Redshanks are closely related to the more abundant Chamise (Adenostoma fasciculatum). Members of this genus are very deep rooted and important slope stabilizers. The foliage is feather-like, allowing the trunk and main branches to show through. The flowers are small but attractive. The fruit is an achene which is valued by small birds. Red Shank is an attractive garden tree, especially when planted in a small grouping.
