The Story

Plant Bio

Dianella tasmanica is a rhizomatous, evergreen perennial with strap-like leaves, forming dense clumps. It produces small flowers followed by attractive, inedible blue berries. 'Variegata' is distinguished by its striking green leaves with bold, creamy-white to pale yellow stripes along the margins. This variegation provides strong architectural interest year-round.

Uses & Benefits:

The striking white and green variegated foliage provides year-round color and architectural form, making it a superb accent plant in borders, containers, or as a massed groundcover. Its delicate blue flowers and vibrant purple berries add seasonal interest.

Its tolerance for drought and coastal conditions makes it a low-maintenance choice for challenging garden spots. It can be used for erosion control on gentle slopes and its clumping nature helps suppress weeds.

The bright blue berries are attractive to and consumed by various bird species, providing a valuable food source. The flowers offer nectar for small native bees and other pollinators.

Planting

How to Grow

Choose a spot with well-draining soil and morning sun.
Dig a hole as deep and twice as wide as the pot.
Gently tease out the roots and place the plant in the hole.
Backfill with soil, ensuring the crown is at soil level.
Water thoroughly to settle the soil around the roots.
Apply a layer of mulch to retain moisture.

Pro Tip

Provide afternoon shade in hottest climates to prevent leaf scorch and maintain vibrant variegation.
