Dianella caerulea or Blue Flax Lilly is a spreading, tufted, herbaceous perennial that spreads by rhizomes, forming clumps of grass-like strappy leaves, up to 70cms long, that are attractive in their own right.
But it also produces lovely star shaped, blue flowers with spectacular orange and yellow protruding stamen from spring through to summer.
The flowers are borne on branching panicles and are followed by persistent indigo blue berries that contain shiny black seeds.
Found in the wild all along the coastal plains, they will grow well in most gardens and are easy to keep. Often seen in parks and as part of municipal plantings.
