A White-Haired Prickly Pear

Opuntia leucotricha is a member of the cactus family, Cactaceae, one of the many prickly pears in the sprawling genus Opuntia. Like its relatives it carries the flattened, pad-like stem segments typical of the group, armed with spines and barbed bristles, and it produces funnel-shaped flowers followed by spiny, fleshy fruits.

Out of Mexico's Drylands

This species is native to northeastern, northwestern and southwestern Mexico, where it grows as a succulent shrub or small tree in desert and dry shrubland. It has since been introduced well beyond that range, turning up in places such as the Canary Islands, Spain, Portugal, Italy, South Africa's Free State and even the Galápagos. It was first described and published in 1828, and over the years it has accumulated numerous synonyms, a sign of how often it was renamed and reclassified as botanists studied it.

Rooting Pads or Seed

Prickly pears like this one are propagated from paddle cuttings or from seed, with cuttings being the faster and more reliable route. A mature, healthy top paddle is twisted free with its base intact, left to dry for at least a day until the wound calluses over, then part-buried cut-side down in well-draining soil and misted rather than watered until roots take hold. Seed propagation is slower and less certain: seeds need their tough coat scratched, a soak, then a cold spell before sowing shallowly in warm, moist soil, where germination can take anywhere from days to months.

Pads, Spines, and Flowers

As a member of Opuntia, this plant grows as a creeping, bushy or tree-like cactus built from flattened, pad-like stem segments. Those pads carry spines and barbed bristles, and the plant flowers in funnel shapes before setting spiny, fleshy fruit.
