Sisyrinchium californicum is a rhizomatous perennial herb producing a pale green, nonwaxy stem which grows up to about 60 centimeters tall. The herbage turns dark brown or black as it dries. The flat, narrow leaves are grasslike. The flower has six tepals each between 1 and 2 centimeters in length.
Plant yellow-eyed grass seed in a cold frame outdoors, or directly in the garden in fall. Yellow-eyed grass thrives in moist, well-drained soil.
Feed yellow-eyed grass yearly in early spring, using a light application of low-nitrogen fertilizer. Water this wetland plant regularly.
