Family Polygonaceae (Buckwheat family)
Eriogonum spp. are shrubby perennials that grow from 1 to 5 feet tall and can spread 5 feet wide or more. Tan to reddish-brown flowers form on the ends of long stems or in clusters, attracting butterflies and birds.
Optimum conditions for growth
Buckwheat is often planted in rock gardens or found covering dry banks. It does well in areas with full sun and requires little to moderate water. In hot climates, water deeply at least twice a month. Buckwheat prefers loose, gravelly soil that is well drained. It tolerates wind and heat. Prune young plants to maintain their shape. Older plants are harder to shape if they weren’t pruned when young.
