Variegated Flax Lily

Dianella caerulea 'Variegata'

The Story

Plant Bio

Dianella are rhizomatous, grass-like perennials with strappy leaves, grown for their foliage, delicate flowers, and ornamental berries.

'Variegata' is prized for its attractive foliage: green, strap-like leaves with distinct white or cream-colored stripes along the margins. It also produces delicate blue flowers followed by shiny, dark blue berries.

Uses & Benefits:

Ornamental UsesThe striking variegated foliage provides year-round color and a strong vertical texture that contrasts well with mounding plants. The delicate blue flowers and subsequent metallic blue berries are an added bonus.
Practical UsesIts excellent drought and heat tolerance make it a superb choice for low-water gardens, rock gardens, and containers in hot climates. It is also useful for adding bright color to dry, sunny borders.
Ecological BenefitsThe flowers attract small native bees and other pollinators. The berries are eaten by birds, though they are considered mildly toxic to mammals.

How to Grow

  1. Select a site with full sun and excellent drainage.

  3. Dig a hole the same depth as the pot.
  4. Gently tease out the roots and place the plant in the hole.
  5. Backfill with soil and water in well to settle.
  6. Water sparingly once established; it is very drought tolerant.
