Roscoea australis is a robust rather leafy species with relatively small mauve flowers that are held in the centre of the plant, often partly sheathed by the top leaves.
The seed pods form much lower in the pseudostems, and as they swell they will burst the pseudostems open. Gary Dunlop wrote: "Roscoea australis was first identified and named by Jill Cowley in her revision of the genus in 1982. It was identified from a herbarium specimen made by Frank Kingdon Ward of his 1956 collection number KW.22124 in northwest Burma (Myanmar)." Jill Cowley wrote: "Roscoea australis grows at 21deg N in the tropical zone, and is isolated from other Indian species of the genus by 3-4 defrees latitude. Its specific epithet, austrais (southern), was given because of this. However, it is geographically closest to R.wardii, which is found in eastern Tibet, Assam, northern Burma, and around the border with Yunnan province in China." Grow Wild Nursery say: "A hardy Ginger that is rare in cultivation and native to Western Myanmar. Plants are robust with glossy, strap-shaped leaves producing a succession of mauve, hooded, orchid-like flowers opening on short stems inside the leaves. Flowering June to August. Height 30 cm. Part sun to part shade in humus rich, well-drained soil." |
