Ixia polystachya, the koringblommetjie in Afrikaans, is a cormous perennial bearing narrow, sword-like leaves. Its flowers may be pink, mauve, blue or white, the centres dark or light.
These plants are 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 flats. I. polystachya is quite variable across this habitat in leaf width, density and size of the inflorescence.
As a garden escape in Australia, it causes problems as a weed (www.pacificbulbsociety.org; Manning, 2009; http://florabase.dec.wa.gov.au).
