This specific species produces yellow/maroon striped waxy flowers with a maroon, circular center. Smells quite disgusting while in bloom (similar to rotting critters) so make sure you're prepared. Though this plant is mainly grown for their flowers, the stems are still fascinating and can still be a conversation piece even when not in bloom. Spikes on stem are soft. These can be found growing under shrubs in the wild so the ideal lighting for them would be dappled light for the entire day.
