Description Flattop buckwheat occurs across the western and central portions of Arizona, its range ending just east of Tucson. This is an excellent pollinator attractor which will bring in butterflies, bees, and flies to the blooms. Birds will eat the seeds, and this plant serves a larval host for several species of moths and butterflies. Because of its relatively small stature, this plant can be used to fill in between larger plants and trees. The overall look of this plant is somewhat similar to a mounding rosemary with its dark green foliage. However, the blooms occur as balled clusters of white/pink flowers which ripen into rusty brown seedheads. Flattop buckwheat is suitable for pollinator gardens in localities across the state in environments ranging from Sedona to Phoenix, Sierra Vista to Ajo. However, given the broad range of this plant in the southwest it would be best to get plants which were grown from seed or cuttings collected near to your planting area.
