The Bunny Ears cactus is a charming desert dweller known for its flat, ear like pads. It is a popular choice for sunny windowsills because of its unique silhouette. Just be careful, as those fuzzy looking spots are actually tiny, irritating spines.

Feed with a balanced liquid fertilizer diluted to half strength during the active growing season.

Propagation

When to plant
spring, summer
Overwintering
Keep the plant dry during the winter months to prevent rot. If kept outdoors in cold climates, ensure the soil is extremely well draining.
In containers
They grow very well in pots, provided you use a container with large drainage holes and a sandy cactus mix.

Pad Cuttings

  1. 1. Carefully remove a healthy pad using tongs.
  2. 2. Let the cut end callous over in a dry, shaded spot for 1 to 2 weeks.
  3. 3. Place the calloused end into dry, gritty soil.
  4. 4. Wait several weeks before watering to allow roots to form.

Group plants with similar low water needs to ensure no one gets overwatered during routine maintenance.

Buenas compañeras

  • Agave They share similar water and light requirements in a desert garden.
  • Yucca These plants provide a nice structural contrast while thriving in the same dry conditions.

Mantenla lejos de

  • Hostas Hostas require too much moisture and shade, which will lead to rot for the cactus.

Especies parecidas

  • Cylindropuntia These are closely related but have cylindrical rather than flattened pads.

Ciencia

Native range
The Americas, ranging from Canada to Argentina.
Conservation
Some rare species are protected, so always ensure your plant is nursery grown rather than collected from the wild.

It survives in harsh, arid environments by storing water in its fleshy pads and using specialized photosynthesis.
