Bunny Ear Cactus

Opuntia microdasys

Bunny Ear Cactus

The Bunny Ear Cactus (Opuntia microdasys) is a charming and easy-to-grow cactus native to Mexico. It features oval, pad-like segments that grow in pairs — giving the appearance of “ears,” hence the name. Each pad is dotted with fuzzy-looking clusters of glochids (tiny barbed spines) that resemble polka dots but can cause irritation if touched.

This cactus is a perfect pick for sunny windowsills, modern décor, or anyone looking for a sculptural, low-water plant. It's slow-growing but can form a compact, branching cluster over time. While it rarely flowers indoors, it may produce creamy yellow blooms in ideal outdoor conditions.

Despite its cute appearance, the glochids are sharp — so it’s best placed out of reach of curious pets and children.
