Bunny Ears Cactus

Opuntia microdasys

Also called Angel's wings, Polka-dot cactus.

Flat, oval pads that pair up like rabbit ears, dotted with soft-looking tufts. Those tufts are tiny barbed bristles, so look but don't stroke.

Key facts

Light
Full sunLots of direct sun, ideally 6 hours or more. A south-facing window (north-facing in the Southern Hemisphere) or outdoors in summer. In dim light new pads grow thin and floppy.
Water
Water deeply when the soil is completely dry, about every 2–3 weeks in spring and summer. Barely at all in winter.
Soil
Gritty, fast-draining cactus mix in a pot with a drainage hole. A heavy clay pot helps stop a top-heavy plant tipping over.
Pets
Pet-safeOpuntia species (listed as "tree cactus") are non-toxic to cats, dogs and horses according to the ASPCA. The tiny bristles can still hurt a curious pet's mouth and paws.
Difficulty
Beginner friendly

Why people love it

Bunny ears is a small prickly pear. New pads grow in pairs on top of older ones, so the plant soon looks like a rabbit poking its ears up. It has no long spines. Instead, each pad is covered in neat polka dots.

Those dots are clusters of glochids: tiny, barbed bristles. They come off at the lightest touch and stick in skin. They look soft. They are not.

Care in a nutshell

  • Full sun. It’s a desert cactus. Give it your sunniest window, or put it outdoors for the summer once nights stay mild. Ease it into strong sun over a week or two so it doesn’t scorch.
  • Soak, then let it dry right out. In spring and summer, water deeply only when the soil is dry all the way down. In winter, give it a sip once a month at most.
  • A cool, dry winter rest. A bright spot that stays cool in winter, around 45–55°F (7–13°C), gives it the best chance to flower. Indoor plants often don’t flower; that’s normal.
  • Handle with care. Use tongs, folded newspaper or thick leather gloves. Fabric gloves catch glochids and pass them on to your hands.

Making more plants

  1. Twist or cut off a pad where it joins the one below. Hold it with tongs.
  2. Leave it somewhere dry and shady for about a week, until the cut end has dried and sealed.
  3. Stand it upright, cut end down, in dry cactus mix. Wait a week before the first light watering.
  4. New roots form in a few weeks. A new pad on top means it’s growing.

Watch out for

  • Glochids in your skin. Lift them out with sticky tape, then tweezers for any that are left. The cacti guide has more on handling.
  • Thin, stretched pads: not enough light. They won’t fatten up again, but new pads will grow normally in more sun.
  • Soft, brown or mushy pads at the base: rot from too much water. Cut off healthy pads and restart them as cuttings.
  • Pale, scorched patches: sunburn after a sudden move into strong sun. The marks stay, but the plant recovers.

Fun fact: Microdasys means “small and hairy” in Greek. It describes the tufts of tiny bristles that give the plant its polka dots.
