|Opuntia robusta growth form.|
J.C.Wendl. ex Pfeiff.
Plants are commonly around 1 metre high, though they may grow to over 3 metres-9 feet high when supported.
The flattened stem segments are fleshy, round and blue-grey in colour. These are up to 30 cm in diameter and have sharp spines up to 5 cm in length. Yellow, sessile flowers with a fleshy base are produced on the edges of the upper stem segments. These are followed by barrel-shaped fleshy fruits which are pink or purple and up to 8 cm long.
The species was first formally described in 1837 in Enumeratio Diagnostica Cactearum hucusque Cognitarum. It has naturalised in the states of South Australia, New South Wales, Queensland and Victoria in Australia.
