Dianella : Greenhouse Plants

C – cool, minimum of 7°C (45°F)

Family: Lhiaceae

E Asia, Polynesia, Australia

These are the Flax Lilies which although not wildly exciting to grow are worth trying for their interesting form and blue berries produced after rather insignificant flowers. Dianella tasmanica will make a clump of 1.5 m (5 ft), whereas D. caerulea, the Paroo Lily, will only reach 60 cm (2 ft) in height. They like to be shaded and kept moist in summer otherwise some leaves and tips of leaves will go brown which spoils the whole appearance of the plant.

Similarly, although they will tolerate frost free conditions their appearance is not improved by cold weather. Both these species produce their berries in autumn. Propagation is by seed sown at 18-21°C (65-70°F), or by division.
