Red Buckwheat is a rare native perennial herb. It is endemic to three of the northern Channel Islands (San Miguel, Santa Rosa, Santa Cruz) but is now widely planted on the mainland. In the wild it tends to grow on dry cliffs, at elevations from 0-700 feet, although it may have been more widespread on these islands before the introduction of domestic livestock. It is a mat-forming plant producing tall, stout flower clusters of white, pink or red flowers. The naked inflorescence rises as much as 12 inches above the leaves. The flowers are held in ball-like clusters at the top, and its long bloom time in summer makes it popular with pollinators, especially butterflies. Leaves are located mainly at the base of the plant and are wavy along the edges, and up to 10 cm long; the upper side is dark green, the underside is very pale. Although it is spreading, it doesn’t spread far or fast and retains a petite form. It is useful in rock gardens, spilling over a wall, or in the understory of larger plants. Despite its island origin, it performs well inland if given some afternoon shade and a little extra water. Two other recognized varieties are found on other islands but these are not available horticulturally.
