Strelitzia juncea, the rush-leaved strelitzia or narrow-leaved bird of paradise, is a monocotyledonous flowering plant that is indigenous to South Africa. This drought resistant Strelitzia occurs sparingly near Uitenhage, Patensie and just north of Port Elizabeth. It is threatened in part by illegal removal for horticultural purposes. This species is thought to be one of the most frost resistant of the genus Strelitzia.
Like the other Strelitzie, it produces a strong root system, with fleshy roots, fine cylindrical leaves that resemble a reed, the floral scape usually grows less than the maximum height of the leaves, which makes it clearly differ from S. reginae. It reaches 2 meters in height.
A well-drained soil is essential for the fruitful cultivation of this species, full sun for an abundant and lasting flowering. It loves regular fertilization with a larger organic fraction than other cultivated species. Fears compact soils due to the original habitat.
