The genus Ixia consists of a number of cormous plants native to South Africa from the Iridaceae family and Ixioideae subfamily. Some of them are known as the corn lily. Some distinctive traits include: sword-like leaves, and long wiry stems with star-shaped flowers. It usually prefers well-drained soil. They have a specific but not very intense fragrance of vegetables. That is why it is often visited by many insects such as bees.

Ixia curvata, commonly known as Roggeveld Kalossie, is a range-restricted South African endemic species found in the Northern Cape, ranging from Hantamsberg near Calvinia to the Roggeveld Escarpment near Middelpos growing on rocky clay soils derived from dolerite and shale amongst fynbos. Flowering occurs from mid-winter to the start of spring from July to September. The leaves are rigid and linear and flowers are deep pink.
