An outstandingly colourful form of this species which we were pleasantly surprised to find in the high mountains of Sumatra in 2005. Where this perennial species was found as scattered plants on the side of the trails with chunky short red much branched stems to 1.2m tall with narrow purple backed leaves to 25cm long, bearing upright terminal bright pink spikes of flowers through the summer into autumn, followed by purple fruit. Although considered poisonous some species are eaten, not something we would recommend. Full sun in any drained soil. Protect from frost.
