Bunny Cactus.
Opuntia (Lehm.) Pfeiff.
Prononciation oh-PUN-tee-uh my-kro-DAY-sis

La cultiver
- Propagation
- cuttings
- 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. Carefully remove a healthy pad using tongs.
- 2. Let the cut end callous over in a dry, shaded spot for 1 to 2 weeks.
- 3. Place the calloused end into dry, gritty soil.
- 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.
Bonnes associations
- 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.
À éloigner de
- Hostas — Hostas require too much moisture and shade, which will lead to rot for the cactus.
Espèces similaires
- Cylindropuntia — These are closely related but have cylindrical rather than flattened pads.
Science
- 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.
- Value to wildlife
- nectar source, nesting cover
- Pollinators
- bees, beetles
- Uses
- ornamental, culinary, xeriscaping
