Silver Streak Flax Lily

Dianella tasmanica 'Silver Streak'

Handsome, strap-like, green and white-striped leaves that will brighten up garden beds and borders. The neat, clumping habit is ideal for massing as a groundcover. Delicate sprays of pale blue-violet flowers appear above the foliage in mid-spring; bright blue berries follow in summer. Evergreen in mild winter climates.
