Native to southern Arizona and New Mexico, Opuntia gosseliniana is one of the prettiest of the Prickly Pears. Its pads are often a beautiful blue and with stress due to cold or lack of water they can turn reddish purple. The new growth also has a purplish tint. The plant can get up to 6 feet tall and across with pads as long as 12 inches. Yellow flowers sometimes cover the plant in April and May.
      I planted this one from a cutting about ten years ago. It's gotten way too big and will have to come out. I'll take plenty of cuttings though and restart it elsewhere.
