Dianella nigra adds year-round interest with its lush foliage, delicate flowers, and vibrant purple-blue berries.

Dianella nigra Care Tips

Dianella nigra prefers partial to full shade and moist, well-drained soil rich in organic matter. Water regularly during establishment, then only in extended periods of dryness. Mulch around the base to retain moisture and suppress weeds. It tolerates light frost and is low-maintenance once established. Remove old or damaged foliage to keep the plant looking tidy.

Plant Size and Spacing

Dianella nigra typically grows 30-60 cm tall and spreads 40-70 cm wide. When planting in groups, space plants about 40-60 cm apart to allow for full foliage spread. This spacing is ideal for creating a groundcover in shaded areas, understorey planting, or edging in native gardens, while also allowing room for its decorative berries to stand out.
