Perennials

Sisyrinchium striatum

Yellow-Eyed Grass

Sisyrinchium striatum forms upright fans of narrow, blue green leaves that create a clean, architectural clump through the growing season. In late spring to early summer, slender branching stems rise above the foliage carrying clusters of small, pale creamy yellow flowers, each marked with subtle brownish veining and a soft golden center.

Native to Chile and Argentina, the species grows in open grassy landscapes and foothill regions of South America.

Design tip

Summer flowers carry the middle of the season, so place it where the bed needs color once spring bulbs fade. It takes sun or light shade, which makes it useful along the changing light of a bed edge or a partly shaded border.
