Introduction
Succulents have captured the hearts of plant lovers worldwide, and among these fascinating plants, Gibbaeum heathii stands out as a true gem. Known affectionately as “baby bums” or “bababoutjies” (Afrikaans for “little baby bottoms”), this quirky dwarf succulent charms growers with its plump, paired leaves and delicate flowers. Native to the rugged landscapes of South Africa’s Little Karoo, G. heathii is more than just a pretty face—it’s a master of survival in harsh, arid conditions.
In this guide, we’ll explore its origins, unique features, and essential care tips to help you cultivate this delightful succulent successfully. Whether you’re a seasoned collector or a curious beginner, G. heathii offers a rewarding growing experience with its playful appearance and resilient nature.
What Is Gibbaeum Heathii?
Gibbaeum heathii is a small, clump-forming succulent belonging to the Aizoaceae family, a group famous for its “living stones” and other drought-tolerant wonders. The genus name Gibbaeum comes from the Latin gibbus, meaning “hump,” referring to the plant’s rounded leaf pairs. The species name heathii honors Dr. Francis Heath, an early succulent enthusiast who contributed to its discovery.
Why the funny nicknames? The plant’s chubby, fused leaves resemble tiny rear ends, earning it playful monikers like “baby bums” and “hondebalvygie” (Afrikaans for “dog’s testicle fig”). But beyond its cheeky appearance, G. heathii is a fascinating study in adaptation, thriving where few other plants can.

Natural Habitat and Ecology
Gibbaeum heathii calls the Little Karoo in South Africa’s Western Cape home. Here’s how it survives in this harsh environment:

- Adaptations:
- Shrivels and retreats into the ground during drought
- Forms a papery sheath to protect new growth
- Hygroscopic seed capsules that release seeds only when wet
How to Care for Gibbaeum Heathii
Light
- Ideal Conditions: Full sun to partial shade
- Too Little Light? Causes stretching (etiolation)
- Too Much Sun? May scorch leaves—provide afternoon shade in extreme heat
Watering
- Summer (Dormant): Minimal water (only if leaves severely wrinkle)
- Winter (Active Growth): Water when soil is completely dry
- Avoid Overwatering: Root rot is a common killer
Soil & Potting
- Best Mix: Gritty, well-draining soil (e.g., cactus mix + perlite/pumice)
- Pot Choice: Shallow, wide containers with drainage holes
Temperature & Hardiness
- Survives Down To: 35°F (1.7°C)
- Best for USDA Zones: 10b-11b (protect from frost if grown elsewhere)
Propagation Methods
Seeds
- Sow in autumn in a well-draining mix
- Keep moist (not soggy) until germination
Division
- Split mature clumps, ensuring each section has roots
- Replant carefully in dry soil
Tissue Culture (Advanced)
- Used by nurseries to mass-produce rare specimens
Challenges and Conservation
Common Problems
- Pests: Mealybugs, spider mites (treat with neem oil)
- Rot: Caused by overwatering—always err on the dry side
Conservation Status
- Not endangered, but wild populations face threats from:
- Illegal collection
- Habitat destruction (mining, grazing)
- Ethical Sourcing: Buy from reputable nurseries, not wild-harvested plants
Fun Facts and Hidden Gems
