Large Opuntia macrocalyx (Bunny Ears Cactus / Polka-Dot Cactus)

Opuntia macrocalyx—better known as the Bunny Ears Cactus or Polka-Dot Cactus—is a plant with real personality. Instantly recognisable for its quirky, pad-like stems covered in neat clusters of golden glochids (tiny bristles), it has a playful look that makes it one of the most beloved cacti for collectors and beginners alike. Its rounded pads often grow in pairs, giving it the charming “bunny ears” nickname.

At Happy Houseplants, we love the way this cactus combines sculptural beauty with easy care. It has a clean, modern silhouette that suits contemporary interiors, while still carrying the wild character of the desert. Over time, the pads stack and branch, creating a striking, architectural plant that always draws attention.

Plant size
You’ll receive a well-rooted plant in a 17cm nursery pot, approximately 35cm tall. A substantial size that makes an instant impact—perfect as a standalone statement or part of a cactus collection.

Native habitat and growth pattern
Native to the arid regions of northern Mexico, the Bunny Ears Cactus thrives in hot, dry climates where it grows upright and branching, forming thickets of pads that can spread widely in the wild. Adapted to cope with strong sun and drought, it has evolved to store water efficiently in its pads and defend itself with those tiny glochids. Indoors, it remains a manageable and highly decorative plant, ideal for bright windowsills and sunny conservatories.

Styling tips
The Bunny Ears Cactus has a bold, graphic shape that looks fantastic in minimal or modern interiors. Pair it with a neutral-toned ceramic pot to highlight its playful pads, or group it with other cacti for a desert-inspired display. Its upright, sculptural form makes it a great choice for side tables, desks, or sunny shelves where it can be admired up close.
