Widespread in fynbos of the Western and Eastern Cape, occurring in marshes and along streams, growing to 1-2 m high. The rhizome has bright red flesh (hence the common names) and is used to produce a reddish brown dye.

Wachendorfia thyrsiflora is by far the tallest of the four Wachendorfia species, usually growing to a height of 1-2 m. Plants grow in seasonally or permanently waterlogged soils in fynbos from Clanwilliam through to Humansdorp, often dominating entire flood plains of lowland streams and producing a mass of yellow flowers from September to December.  

Flowers last for less than a day but do not open simultaneously so that during the flowering season there are usually a few flowers open on each pannicle. 

The red-coloured flesh of the rhizome is characteristic of all four species and is used to make a reddish brown dye.
