Flat grass-like leaves originate from the plant base and alternately along the stem. Flowers in umbel-like cymes at the top of 16 in. branching stems. © Joan Avise

Blue-eyed Grass

Sisyrinchium bellum

In Orange County in this family, there is only one native species and seven scarce exotics that are escapees from cultivation. Plants in Iridaceae are perennial herbs with parallel-veined, narrow, sheathing leaves folded lengthwise to enclose the next one within (equitant=leaves overlapping in two ranks and usually folded along midrib; Clarke).  The fruit is a triangular dry capsule that opens at maturity to disperse the seeds. 

Blue-eyed grass is a fairly common annual or short-lived perennial on seasonally wet clay, coastal sage scrub, and especially moist grasslands ( (UCI Ecological Preserve, UCI Freshwater Marsh, Fairview Park, Bommer Canyon, Crystal Cove State Park, Limestone Canyon Wilderness Park (Roberts). The plants grow in colonies, propagated from rhizomes (below-ground clone forming stems) or seed. Flowering Feb - May. Spanish Americans brewed tea from the roots for use in reducing fever (Nancy Dale).
