Is a deciduous evergreen perennial. It grows up to 2 m tall. Leaves erect, 20 mm wide, grey-green, in a loose fan. It produces five tall flower spikes with up to 7 large, intensely scarlet orange to red or variously coloured, hooded flowers with a bright yellow throat; bracts green to red-brown, clasping. It should preferably be planted in light, well-drained, sandy loam soil in full sun. As this is a summer-growing species, plant corms in spring (around September) and give plenty of water all through the growing season.
