About this plant

Beach flax-lily is a spreading coastal perennial with strap-like leaves, blue flowers and blue-purple berries. It naturally grows on sandy coastal dunes and spreads by rhizomes, making it useful for sand binding and ground-layer habitat. Allow room for an expanding mat or grow it in a broad container.

More plant details

Garden uses: Coastal planting, sand stabilisation and spreading ground-layer habitat; allow room for rhizomes or contain the plant in a broad pot.
Wildlife value: Dianella congesta provides a useful seasonal flower resource for native bees and other insects. Dianella congesta provides valuable seasonal nectar, fruit or other food for local birds. Dianella congesta adds low or climbing cover and helps connect habitat at ground or understorey level.
Flowering and fruiting: Blue-purple flowers are followed by decorative blue berries on branching stems.
Growth habit: Rhizomatous, mat-forming coastal perennial herb with strap-like leaves.
Cautions: Spreads by rhizomes and can form a large mat rather than a compact permanent clump. Allow space and use verified local provenance for restoration.
