Found from low to high elevations, arrowleaf buckwheat prefers dry, sunny locations with rocky or gravelly soil, open grassy hillsides or rock outcrops. The early summer flowers can be either creamy white or yellow, depending on location. On the northern side of the Siskiyou Crest (Rogue and Illinois River Watersheds) arrowleaf buckwheat flowers are creamy white; however, on the southern (Klamath River) side, the flowers are almost always yellow. The large, arrow-shaped leaves are green on top and woolly white beneath. The flowers are prized by numerous native pollinators, including native bees, pollinating flies, beetles, butterflies and wasps. Wild buckwheats, in general are used by many species of butterfly as larval host plants. Perfect for a sunny, dry location or large rock garden.
