Dianella caerulea

Dianella caerulea (picture on www.jackdawsfield.co.uk) has glossy strap-like leaves making a clump to about 90cm. Its flowers are blue with prominent yellow anthers, borne in erect panicles, and these can be followed by blue berries. Again it is Z9, but experience in this country suggests that it thrives in sheltered places – e.g. the base of a wall. This species is smaller in ultimate size than the similar D. tasmanica but seems equally vigorous as a young plant.
