Dianella Plants or Flax Lily. Dianella are a widely used strappy leaf plant with landscaping applications and are a great alternative to New Zeland Flax..
With over 15 species such as Dianella revoluta, Dianella caerulea (Paroo lily) and Dianella tasmanica being native to Australia they are widely used in revegetation projects and roadside situations. All species are best described as a flowering tufting grass or strappy leaf plant.
A desirable plant in both major landscaping projects and the home garden, tolerant of a wide range of temperatures, drought and frost resistant, nice foliage, flowers and reportedly edible fruits in the form of berries from some species.
Commonly found in the bushland in eastern Australia, Dianella are becoming increasingly popular as a garden plan where a clump forming plant with a grass-like appearance is required.
Dianella do not like wet feet, and once established are virtually drought tolerant. Dianella caerulea is a great plant, drought tolerant and able to cope with a variety of conditions.
Sometimes referred to as Flax Lilies, some species of can form clumps up to one metre in diameter.
All species are suitable for us as a border plant in rockeries or cottage gardens, even a small hedge.
