Dianella BluTopia ['DP401'] PP27,348 (Blutopia Flax Lily) - A distinctive soft blue colored strap-leafed upright clumping perennial to 24 to 30 inches tall by 20 inches wide with 2 inch wide blue-green lance shaped leaves that are slightly v-shaped with a central keel and a fine red margin near the leaf base. In late spring into summer on a 3-foot-tall branching inflorescence with red tinged gray stems appear the dark purplish buds that open to display violet blue star shaped flowers with yellow stamens.

Plant in full sun to light shade and irrigate regularly to only occasionally. Grows well in sandy and other well drained soils but can tolerate some wet soil situations and mounded heavier soils. Evergreen to 24° F and reportedly root hardy to around 10° F and useful in gardens in USDA Zones 8-11. Trim spent flowers to keep plants neat looking. This is a great looking plant in and out of bloom, looking like a neat small blue-gray New Zealand Flax (Phormium sp.) with attractive tall flower stems.

The genus is named after Diana, the Roman goddess, of hunting and Queen of the woods. Dianella BluTopia comes from the breeding program of Graham Brown at the University of Sydney Plant Breeding Institute in Cobbitty, New South Wales, Australia and was the result of open pollination of Dianella prunina Utopia ['DP303'] with nearby plants of Dianella caerulea Cassa Blue ['DBB03']. In August 2010 one seedling plant was selected that had foliage resembling the pollen parent Cassa Blue ['DBB03'] but with broader leaves and more vegetative shoots than either parent. The plant has the form of a robust slightly larger and very full Dianella Cassa Blue ['DBB03'] with the nice tall flowers from Dianella Utopia 'DP303'. It was given the cultivar name 'DP401' with which it received US Plant Patent PP27,348 on November 1, 2016. The seed parent Dianella Utopia 'DP303' has long been noted as an incredibly good-looking plant, but unfortunately it had an open habit that would collapse under the weight of its tall flowering stems, however this new hybrid is markedly stronger and does not suffer from this problem.

Because it is the result of the cross between Cassa Blue and Utopia, 'DP401' it is marketed by the Dig Plant Company as BluTopia, a clever combination of the marketing names of its parent plants Cassa Blue and Utopia. 'DP401' is also marketed in the Southern Living and Sunset Western Garden plant collections under their own trademarked name. The image on this page courtesy of Ozbreed Plants. We have grown the nice Flax Lily since 2018.
