This member of the Amaryllidaceae family was given this name by Robert Brown in 1810. It is found in western New South Wales, north-western Victoria and in South Australia, growing in a well drained soil with some water and some to lots of sun. The bulb can grow to two or even up to six centimetres in diameter, the entire plant to 30 centimetres in height, 50 with the inflorescence. The flowers are pink to purple. The leaves forms during winter while the inflorescence with the six to ten flowers are found in the mid summer.
The name Calostemma originates from the Greek: kalos meaning 'beautiful', and stemma, 'crown'. The species name purpureum is from Latin: 'purple'.
