Ixia polystachya, the koringblommetjie in Afrikaans, may have pink, mauve, blue or white flowers. The centres may be dark or light. A cormous perennial with narrow, sword-like leaves, the plant is found over a large part of the western parts of South Africa in the Northern Cape and Western Cape. It grows on sandy and stony slopes and flat land.
Ixia polystachya is quite variable across this habitat in leaf width, density and size of the inflorescence and as indicated, the flower colour. As a garden escape in Australia, it causes problems as a weed (www.pacificbulbsociety.org; Manning, 2009; http://florabase.dec.wa.gov.au).
