3. Origin & Distribution

Native to Madagascar; now widely cultivated worldwide as an ornamental houseplant. Naturalized in parts of Africa, South America, southern Europe, and the southern United States.

4. Visual Characteristics

Evergreen succulent with pairs of fleshy, glossy green leaves featuring scalloped margins. Produces dense, dome-shaped clusters (cymes) of double, rose-like white flowers atop erect, succulent stems. Blooms last several weeks under optimal conditions.

5. Size & Dimensions

Typical height: 15–30 cm (6–12 in); spread: 15–30 cm (6–12 in). Flower clusters measure up to 8–10 cm (3–4 in) in diameter.

6. Light Requirements

Prefers bright light to full sun; at least 4–6 hours of direct or bright indirect light per day. In low light, foliage remains healthy but flowering is reduced.

7. Watering Needs

Allow the top 2–3 cm of soil to dry out between waterings. Water thoroughly until excess drains, then discard any standing water. Reduce frequency in autumn and winter.

8. Soil & Potting

Use a well‐draining succulent or cactus potting mix, amended with perlite or pumice. Ideal soil pH is 6.0–6.5. Always plant in containers with drainage holes.

9. Temperature & Humidity

Optimal daytime temperatures: 15–29 °C (60–85 °F); minimum: 10 °C (50 °F). Prefers average indoor humidity (40–60%). Avoid cold drafts and high humidity that can promote rot.

10. Fertilization

Feed every 2–4 weeks during active growth (spring–summer) with a balanced, water‐soluble fertilizer at half strength. Do not fertilize during dormancy (autumn–winter).

11. Maintenance & Care Level

Low maintenance and easy care. Deadhead spent blooms to encourage rebloom and prevent seed formation. Light pruning maintains compact shape and prevents leggy growth.

12. Growth & Propagation

Propagate via leaf or stem cuttings and offsets. Requires short‐day photoperiod (10 hours or less of light) to initiate flowering; providing extended darkness (12–14 hours) for 6–8 weeks can induce bloom.

13. Common Problems

Overwatering can lead to root and stem rot. Pests include mealybugs, aphids, and spider mites. Powdery mildew may occur in high humidity. Leaf yellowing can indicate nutrient deficiency or cold stress.

14. Benefits & Uses

Popular ornamental houseplant and gift for brightening indoor spaces. Long-lasting blooms used in container gardens, mixed planters, and cut‐flower arrangements.

15. Toxicity & Safety

Toxic to cats, dogs, and livestock if ingested; contains bufadienolide compounds that can cause gastrointestinal upset and cardiac disturbances. Keep out of reach of children and pets.
