A tall, tender evergreen succulent reaching 2m. It has thick grey-green strap-like leaves with sharp red spines along the edges, in a slightly irregular rosette. It is usually unbranched but is sometimes multi-stemmed. The flowers normally form in shorter days as very tall spikes. Each tubular flower hangs but then tilts upwards at the opening. They are deep orange in bud, ripening to orange then opening more yellow
