This cactus, native to Argentina, has an unusual growth habit for a cactus. It does not get any taller than about three feet at maturity, and has sprawling limbs that grow just as wide. Large flowers, generally six to eight inches in diameter are white with yellow centers. They appear at night, sometimes lasting into the early morning or even longer on cool, cloudy days. Flowers are followed by a purple fruit, with a red pulp. Blossoms are wonderfully fragrant and attract night pollinators such as bats and moths.
