San Miguel Island Buckwheat | Eriogonum grande var. rubescens
San Miguel Island Buckwheat is a California native perennial prized for its vibrant clusters of pink to red blooms that rise above low, silvery-green foliage. Endemic to the Channel Islands, it thrives in coastal gardens and is highly attractive to pollinators, especially butterflies. Its drought tolerance, compact form, and long blooming period make it an excellent choice for rock gardens, borders, and native plant landscapes.
