The Dapple Designs Expert Says:

Dianella caerulea 'Cassa Blue', also known as Cassa Blue Flax Lilly is a small strappy leafed plant with rich blue foliage that has a far superior flower display compared to most Dianellas. Often two months of flowers in spring, followed by a month of beautiful purple berries. It tolerates a wide range of soils and climatic conditions. Hardy with excellent cold, heat, frost and drought tolerance.
