Cotyledon orbiculata 'Macrantha' is a drought-tolerant succulent from the Crassulaceae family, native to the rocky landscapes of South Africa. It grows on neglect and minimal intervention, with suitability for both beginner plant parents and seasoned collectors.
Macrantha produces plump, rounded leaves with a powdery coating and red margins that deepen in strong light. The plant grows upright and clumping with large, spoon-shaped foliage. It reaches 12 to 24 inches in height with a similar spread as it clumps outward over time.
During late spring and summer, it sends up tall, arching flower stalks topped with pendulous, tubular blooms in coral-red to orange shades. A drop in night temperature encourages blooming, so moving it to a cooler spot in the evening can trigger flowering.
Position it on a bright windowsill, sunny patio, or summer garden bed. You can leave it up to ten days without water. Protect it from rain to prevent overwatering and root rot. The sap causes skin and paw irritation in cats, dogs, and small children; keep it on a high shelf out of reach. Rotate it regularly so every side receives even light exposure.

Cotyledon orbiculata 'Macrantha' grows well in bright indirect light to full sun, with partial sun tolerated indoors.
Water it deeply every 10 to 14 days in summer, reducing to once a month in winter.
Macrantha performs best in gritty, well-draining cactus and perlite mix to prevent root rot.
It prefers temperatures between 50 and 80°F and should be brought indoors before frost.

Q: How often should I water Cotyledon orbiculata 'Macrantha'?
A: During the growing season, allow the soil to dry completely between waterings. Watering frequency varies by season, pot size, and indoor humidity levels. In winter, reduce applications significantly to prevent rot in dormant tissue.
Q: Is it safe around pets?
A: Cotyledon orbiculata 'Macrantha' is toxic to cats and dogs. The sap irritates skin and paws on contact, and ingestion causes gastrointestinal upset. Keep it on a high shelf well out of reach.
Q: Does Macrantha need a south-facing window?
A: A south or west-facing window provides the strongest light, but it tolerates bright indirect light and partial sun indoors.
Q: How large does it get?
A: Macrantha typically reaches 12 to 24 inches tall with a similar spread as it clumps outward. Growth pace allows it to remain a manageable size indoors for many years before repotting becomes necessary.
Q: Can you propagate Macrantha from cuttings?
A: Stem and leaf cuttings establish themselves readily when allowed to callous for a day or two before insertion into dry, gritty soil. Placement in warm, bright conditions accelerates root formation.
Q: Can it survive outdoors year-round in my region?
A: Macrantha is hardy outdoors year-round only in USDA zones 9 through 11. If you live outside those zones, move it indoors before your first frost to prevent damage.
