Opuntia Elata – Orange Tuna / Riverina Pear

Opuntia elata, commonly known as Orange Tuna or Riverina Pear, is a striking, fast-growing cactus native to South America, including Argentina, Brazil, Paraguay, Bolivia, and Uruguay . This impressive plant grows as a much-branched shrub reaching up to 2 meters (6.5 feet) tall, developing a woody trunk over time and creating a dramatic, architectural presence in any garden .

Distinctive Features

The pads (cladodes) are glossy green, oblong to spoon-shaped, measuring 15–25 cm long and 4–9 cm wide . Unlike many prickly pears, this species is often spineless or carries only 1–3 spines per areole, giving it a smoother, more refined appearance . However, it still features reddish-brown glochids (tiny barbed bristles) that can irritate skin, so handle with care .

Vibrant Blooms and Colourful Fruit

In spring to summer, Opuntia Elata produces stunning cup-shaped flowers in brilliant orange or yellow, occasionally tinged with red, measuring 3–4 cm in diameter . These are followed by obovoid, purple fruits that add further ornamental interest
