How to grow Dianella tasmanica successfully in NZ

Dianella tasmanica, or Tasman Flax Lily, prefers full sun to part shade and thrives in moist, well-drained soil enriched with organic matter. Water regularly during establishment, then only during extended dry spells. Mulch around the base to retain moisture and suppress weeds. This hardy evergreen tolerates frost and coastal conditions. Prune back old foliage annually to refresh the plant. Ideal for borders, mass planting, and low-maintenance gardens.

Dianella tasmanica spacing

Dianella tasmanica typically grows 60 to 90 cm tall and 45 to 60 cm wide. For mass planting or borders, space plants about 50 to 60 cm apart. This allows room for each plant to mature fully while creating a dense, attractive display over time.
