Blue-eyed grass

Text & photo by Marian Hengemihle

Sisyrinchium angustifolium

This native is not a true grass but a member of the iris family, a small blue-eyed beauty that should not be missed.  Growing about 12 inches tall, this clump-forming perennial features narrow grass-like leaves and violet-blue flowers with a yellow center that appear on branched flowering stems. The flowers will bring a smile in May and June. Plant in front beds, borders, along pathways, and woodland gardens in full sun to part shade in moist soils. Division may be needed every 2-3 years to keep plants vigorous. Shear back after bloom to prevent any unwanted seedlings. Best of all, blue-eyed grass is not bothered by deer.
