DescriptionWachendorfias have basal tufts of long, narrow, pleated leaves and bear erect spikes of starry, yellow flowers in spring and summer. Their common name stems from the red sap of the corms, used as a dye, and the bright red-orange colour of the roots themselves. Red colour is a feature of many plants in the family Haemodoraceae (Haemo = Blood).[4] CultivationSlightly frost hardy, Wachendorfias thrive outdoors in warm, near frost-free environments as an ornamental plant. Most require moist, well drained soils in a sunny position. Some are ideal for bog gardens. Propagation is via seed or division.[5] Gallery{{Commonscat|Wachendorfia}}References1. ^1 2 Kew World Checklist of Selected Plant Families {{Taxonbar|from=Q2709942}}2. ^Burman, J. 1757.
