Dianella tasmanica

Common Name: Tasman Flax Lily

Description:
Dianella tasmanica, commonly known as the Tasman Flax Lily, is a hardy, clumping perennial native to southeastern Australia, including Tasmania. It features strappy, deep green foliage that forms dense, grass-like clumps, making it an excellent choice for mass plantings or borders. In spring and summer, it produces delicate blue to violet star-shaped flowers on tall stems, followed by striking, glossy purple berries that persist into autumn. This plant thrives in a variety of conditions, from full sun to deep shade, and is highly tolerant of coastal conditions, frost, and dry periods once established. Dianella tasmanica is perfect for low-maintenance gardens, providing year-round texture and colour. It grows well in sandy, loamy, or clay soils and prefers well-drained conditions with occasional watering during extended dry spells.
