Opuntia microdasys – Bunny Ears Cactus with Bold Desert Style
Opuntia microdasys, also known as Bunny Ears or Angel’s-wings cactus, is a compact, low-maintenance species native to arid regions of Mexico. Its oval pads are covered in dense clusters of tiny barbed glochids that give a fuzzy appearance—but don’t be fooled: they detach easily and can irritate skin. This unique desert cactus is perfect for bright interiors or dry, sunny balconies in frost-free climates.
With consistent sun and minimal watering, it slowly forms symmetrical clumps that resemble a cluster of bunny ears. Though flowering is rare indoors, mature plants may produce bright yellow blooms in strong light. Its sculptural silhouette and hands-off care make it a favorite among minimalist plant collectors.
Why Opuntia microdasys Is a Must-Have

- Desert Resilience: Thrives in dry, hot conditions; great for sunny windowsills
Natural Habitat and Botanical Background
- Native Range: Dry plains and rocky slopes of northern and central Mexico
- Botanical Authority:Opuntia microdasys (Lehm.) Pfeiff., published in Enum. Diagn. Cact. 154 (1837)
- Basionym:Cactus microdasys Lehm.
- Climate: Intense sun, low rainfall, warm air, low humidity
How to Care for Opuntia microdasys
Light
- Requires direct sun – at least 6 hours daily
- Ideal in south- or west-facing windows
- Stretching (etiolation) occurs if light is too low
Watering
- Water only when soil is bone dry – every 2–4 weeks
- Always use a pot with drainage holes
- No strict seasonal schedule indoors – adjust by light and warmth
Temperature and Humidity
- Optimal range: 21–35 °C
- Tolerates down to 10 °C; protect from frost
- Prefers dry air (below 50% RH); never mist
- Outdoor dormancy: In cooler climates, growth slows below 15 °C with no need to force dormancy indoors
Soil and Potting
- Use cactus mix with added sand, grit, or perlite
- Terracotta pots help regulate moisture and improve airflow
Repotting
- Repot every 2–3 years or when rootbound
- Handle with gloves or tongs to avoid glochids
Feeding
- Fertilize monthly in warm months with cactus fertilizer (low nitrogen)
- No feeding necessary during slower growth phases
Propagation
- Let a mature pad callous for 2–3 days before planting upright in dry mix
- Water lightly only after rooting begins (1–2 weeks)
Pruning
- Remove damaged pads or shape the plant using clean, sharp tools
Common Problems and Fixes
Pests
- Mealybugs, scale, spider mitesRemove manually, apply neem oil or insecticidal soap
Root Rot
- Symptoms: Soft, dark pads; base collapse
- Fix: Remove rot, replant in dry soil, and adjust watering frequency
Sunburn
- Symptoms: Pale, dry patches on exposed pads
- Fix: Introduce to full sun gradually
Additional Tips
- No support needed: Naturally upright and compact
- Not frost-hardy: Bring indoors before temperatures drop below 5 °C
- May bloom when mature: Yellow flowers under intense light, but rare indoors
