16°C – 32°C

Bunny ear cactus, Opuntia microdasys, is native to central and northern Mexico, where it grows as a small, spreading, clumping cactus adapted to arid desert conditions. It belongs to the cactus family, Cactaceae, within the large and widely distributed genus Opuntia, commonly known as prickly pear, which includes over 200 species found across the Americas. The plant's most recognizable and defining feature is its flattened, paddle-shaped stem segments, called pads or cladodes, which emerge characteristically in pairs from the top of a parent pad, giving young plants their distinctive "bunny ear" silhouette that gives the species its common name — a juvenile plant often shows exactly two small paddles rising from a single base, closely resembling a rabbit's upright ears.

Despite the plant's soft, fuzzy-looking appearance — a texture that has also earned it the alternate common name polka-dot cactus, referencing the small, evenly spaced tufts of fine bristles dotting the surface of each pad — Opuntia microdasys is, in a genuinely important and somewhat counterintuitive sense, more hazardous to handle than many spinier, more obviously threatening cacti. The plant lacks the large, easily visible, easily avoided spines typical of many other cacti, but its pads are instead covered in dense clusters of tiny, hair-like, barbed structures called glochids, generally golden-yellow or white in color. These glochids detach from the plant with only the slightest touch, are nearly invisible against skin once embedded, and are notoriously difficult and uncomfortable to remove once lodged — a genuinely deceptive hazard, since the plant's soft, almost cuddly visual appearance gives no real indication of just how readily and effectively these bristles will embed themselves in skin on contact, and gloves along with careful, deliberate handling are strongly recommended whenever the plant needs to be touched, repotted, or pruned. New pads often emerge in a fresh reddish tone before gradually maturing into the soft, velvety green color typical of established growth, creating an attractive color gradient across a well-established, multi-pad specimen as older and newer growth sit side by side; individual pads can grow up to roughly six inches across, with the overall clumping plant typically reaching around one to two feet in height and spread once mature.
