A little like a smaller, pink version of I. tinctoria, this originates in South Africa where it is confined to a very few locations in the Eastern Cape and KwaZulu-Natal. Forms a plant 60 to 100cm with red tinted stems and broad pink flowers with a spur at the rear produced in late summer/early autumn. Easy in semi-shaded conditions in never too dry but well drained soil. Dig up the tubers and store cool over winter, or chance them with a deep mulch as this is reasonably hardy. This particular form is a good rich-pink. Not remotely invasive!
