Dianella ensifolia has bamboo like growth, sprouting from a rhizomatous root system. With a distribution through the Old World Tropics it has flourished in a tub positioned beneath a raised walkway. Effectively a dank basement area in the sunken courtyard of the Front Range glasshouses. Here with low light levels it exhibits a spectacular crop of berries, shiny glossy blue.
A monocot with sheath like linear foliage, a rough midrib runs the length of the leaf. The stems have overlapped brown sheaths giving an attractive contrast to the mass of evergreen foliage.
