Products > Dianella caerulea Cassa Blue ['DBB03'] PP17,998   Dianella caerulea Cassa Blue ['DBB03'] PP17,998 - Blue Flax Lily     [2nd Image] Habit and Cultural Information Category: Grass-like Family: Phormiaceae (~Xanthorrhoeaceae) Origin: Australia (Australasia) Evergreen: Yes Flower Color: Light Blue Bloomtime: Spring/Summer Synonyms: [Dianella caerulea 'DBB03'] Height: 1-2 feet Width: Spreading Exposure: Sun or Shade Summer Dry: Yes Irrigation (H2O Info): Low Water Needs Winter Hardiness: 0-10° F Dianella caerulea Cassa Blue ['DBB03'] PP17,998 (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. Evergreen to 24ºF and is root hardy to at least 10ºF. Great as an accent plant or for a mass planting where the recommended spacing is 2 to 3 feet. This plant come from Tod Layt of OzBreed Plants of New South Wales, Australia and is being marketed in the US by Celebrated Plants (VersaScapes) of Mt. Pleasant South Carolina. It was first discovered in 1996 at an Australian nursery in Clarendon, New South Wales. The one known parent plant is Dianella caerulea 'Sydney Ecotype', which is a taller cane forming plant with yellow green leaf color. The breeding program involved open pollination and several other Dianella species were growing in the same location, including D. longifolia, D. revoluta and D. tasmanica. Though this plant is listed by its inventor and on its US patent application as a selection of Dianella caerulea, its pollen parent is thought possibly to be Dianella longifolia because of the similar color and growth habits it shares with this species. This plant is being marketed as Cassa Blue but its cultivar name is 'DBB03'.  Information displayed on this page about  Dianella caerulea Cassa Blue ['DBB03'] PP17,998 is based on the research conducted about it in our library and from reliable online resources.
