Ookow, Fork-Toothed Ookow, Blue Dicks, Brodiaea congesta


Dichelostemma congestum (Ookow) is a cormous perennial boasting showy rounded clusters packed with 6-15 lasting lilac-purple flowers in early summer. Attractive to bees, they are borne atop straight and slender stems above the foliage of narrow, grassy leaves that die down as the flowers open.
