Santa Cruz Island buckwheat
A large, shrubby buckwheat with narrow, pale green foliage and sturdy, flat-topped inflorescences of creamy white to pink flowers. The flowers age over time, eventually turning reddish brown, remaining ornamental for a long period. Grows 3 to 4 ft. tall and slightly wider. Normal to very lean well-drained soils. Especially drought tolerant along the coast, may need infrequent summer water inland and possibly a little afternoon shade. Buckwheats are excellent additions to habitat gardens, providing pollen and nectar for bees and butterflies and seeds for many creatures. Deer resistant.
