Dianella 'Cassa Blue'
Dianella caerulea 'Cassa Blue' (Blue Flax Lily) - A distinctive, compact, soft blue, medium-textured, strap-leafed perennial to 18 inches tall by as wide. In later winter into spring and sometimes on to summer appear yellow-throated dark blue flowers that rise in a delicate inflorescence about 1 foot above the foliage and are followed by large lilac-blue colored fruit. Blooms a little earler than 'King Alfred'. This is one of the slower growing more clump-forming types of Dianella that doesn't spread by wide growing rhizomes - it is also a non-cane-forming selection of Dianella caerulea, remaining as a tuft of foliage at ground level. Plant in full sun to light shade and irrigate only occasionally to regularly. Grows well in sandy soils and reportedly tolerates heavy clay if planted on a slope or mound to insure adequate drainage.
