Opuntia microdasys, commonly called the bunny ear cactus, is a clump-forming prickly pear native to arid regions of central and northern Mexico. It grows as segmented, oval pads borne in pairs that resemble rabbit ears. Unlike many cacti, it lacks long spines; instead, each areole carries dense tufts of barbed glochids that detach readily and irritate skin, so handling requires care. Mature plants reach 30–60 cm tall and wide, branching freely over time. In bright, warm conditions, it produces large, satiny yellow flowers in late spring to summer, sometimes followed by small reddish fruits. Pads are deep green and photosynthetic, storing water efficiently for drought tolerance. As a houseplant, it thrives in fast-draining mineral potting mixes, abundant sun, and sparse watering. It is well suited to windowsills, balcony planters, and xeric outdoor beds in frost-free climates. Indoors or out, excellent drainage and a dry, airy root zone are essential to prevent rot.

How to care for Bunny ear cactus
Water
Water deeply only after the mix has dried completely from top to bottom. In warm, bright conditions this may be every 2–4 weeks; in winter, reduce to once every 4–8 weeks or less if kept cool. Drench until water exits the drainage holes, then discard runoff. Avoid frequent sips and never allow the pot to sit in water. Keep water off pads to reduce blemishes and fungal issues.
Light
Give abundant light: 6–10 hours of direct sun daily. A south or west-facing window, sunroom, or unobstructed balcony is ideal. Outdoors, full sun produces compact pads and flowering; acclimate over 2–3 weeks to avoid sunburn. Under insufficient light, pads elongate and lose their flat, paired form. In very intense desert sun, provide light afternoon shade for young or freshly repotted plants.
Nutrients
Feed lightly during active growth (spring through mid-summer). Use a low-nitrogen cactus fertilizer, such as 2-7-7 or 5-10-10, at 1/4–1/2 strength every 4–6 weeks after a thorough watering. Avoid high nitrogen, which promotes weak, etiolated pads. Do not fertilize in fall or winter, or within 4–6 weeks after repotting. Flush the soil with plain water occasionally to prevent salt buildup, especially in gritty, inorganic mixes.
Temperature
Best growth occurs between 21–32°C days with cooler nights. Provide a cool, dry rest around 10–15°C in winter if possible. It tolerates brief dips to about 5°C when bone-dry, but it is not frost-hardy; freezing damages pads. Indoors, keep above 7°C and away from cold drafts. In heatwaves above 37°C, increase airflow and shade during the hottest hours to prevent pad scorching and root stress.
