Flowers are large and showy, foul-scented and covered in fine white hairs. These are coloured green on the outer surface and red-purple on the inner surface. Some species are highly patterned, usually in the form of striping, these star-shaped flowers are fleshy and furry and vary greatly in their shading and patterning across species.
