About Redflower Buckwheat (Eriogonum grande) Eriogonum grande is a species of wild buckwheat known by the common name redflower buckwheat. It is native to the Channel Islands of California, as well as northwestern Baja California. It is a mat-forming perennial herb producing tall, stout flower clusters of white, pink, or red flowers. Its long bloom time in summer makes it popular with pollinators. Leaves are located mainly at the base of the plant and are wavy along the edges and up to 10 centimeters 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. There are three recognized varieties in the wild. Var. rubescens is the most commonly available form found in nurseries.
