Yellow Eyed Grass (Sisyrinchium californicum) is a perennial herb that naturally grows in moist environments. It is a member of the Iris family, with blade-like leaves. Yellow star-shaped flowers appear from May through June. It forms small clumps and self-sows in favorable conditions, and does best in full sun with regular watering.
Yellow Eyed Grass is adaptable to many types of soil. On the coast it takes full sun and inland grows in part shade. Yellow Eyed Grass is great for moist meadow gardens, rain gardens, in containers, or borders with adequate irrigation.
