Abstract

‘DBB03’ is a distinctive variety of Dianella caerulea, which is characterized by the combination of its open growth, a blue-green foliage, pale blue flowers, slightly spreading and semi-compact growth habit, and an absence of canes, which is unusual for a Dianella caerulea, particularly when compared to the ‘Sydney Ecotype’. ‘DBB03’ is also less prone to falling over than the parent type.
