The “porcelain succulent” (Pachyphytum oviferum), also known as “Moonstones” or “Sugar Almond Plant,” is a captivating succulent native to Mexico. Its distinctive plump, egg-shaped leaves range in color from pale blue-green to bluish-purple, pink, or peachy-orange. This plant’s charming appearance and relatively straightforward care make it a popular choice for succulent enthusiasts.
The Unique Porcelain Coating
The porcelain succulent’s distinctive powdery coating, known as farina or epicuticular wax, gives it a “porcelain” or “pearly” appearance. This natural layer serves several functions: it acts as a sunscreen, protecting leaves from intense sunlight and preventing sunburn. Farina also repels water, reducing fungal infections, and conserves the plant’s internal moisture, beneficial in arid habitats. Avoid touching or wiping off this farina, as it removes its protective benefits and leaves permanent marks.
Caring for Your Porcelain Succulent
Light
Pachyphytum oviferum thrives in bright, indirect light, benefiting from at least six hours of daily sunlight, ideally morning sun. Protect it from harsh afternoon direct light. Insufficient light causes etiolation, leading to leggy growth and faded foliage. Conversely, excessive direct sunlight, especially during peak heat, can sunburn leaves, appearing as brown or yellow scorch marks. Indoors, a south or west-facing window is suitable, but a sheer curtain can diffuse intense light. Rotate the pot regularly for even exposure and symmetrical growth.
Watering
Correct watering is important for Pachyphytum oviferum, as overwatering is a common issue. Use the “soak and dry” method: thoroughly saturate the soil, then allow it to dry completely before rewatering. The plant’s plump leaves store water, making it drought-tolerant. Wrinkled leaves indicate underwatering, plumping up after a good soak. Overwatering causes soft, mushy, or translucent leaves and can lead to irreversible root rot. Reduce watering significantly during cooler fall and winter months when growth slows.
Soil
A well-draining, gritty, and aerated soil mix is important for porcelain succulents to prevent waterlogging and root rot. Standard potting soil is unsuitable due to its moisture retention. An ideal mix includes components like perlite, pumice, or coarse sand, combined with a smaller proportion of potting soil or compost. Pre-made cactus and succulent mixes are also a convenient option. Ensure the pot has drainage holes to allow excess water to escape.
Temperature and Airflow
Pachyphytum oviferum prefers average room temperatures, thriving between 60°F and 85°F (15°C to 29°C). It is not frost-tolerant; temperatures below 20°F (-6°C) can cause damage. Bring outdoor plants indoors during colder months. Good air circulation prevents fungal issues and promotes plant health. Place the succulent in a location with gentle air movement, away from cold drafts, to help the soil dry and reduce humidity.
Propagation and Repotting
Pachyphytum oviferum is easy to propagate from individual leaves or stem cuttings. For leaf propagation, gently twist a healthy leaf from the main stem, ensuring a clean break, then allow the detached leaf or cutting to callus for a few days in a shaded area before placing it on or slightly in well-draining soil. Repotting is infrequent for this slow-growing succulent, typically every two years or when it becomes root-bound. When repotting, choose a pot only one to two inches larger than the previous one, as larger pots can hold too much moisture. Handle the plant gently to preserve its delicate farina coating.
Troubleshooting Common Issues
Common issues with porcelain succulents often stem from improper care. Wrinkled or shriveled leaves indicate underwatering, while soft, mushy, or translucent leaves signal overwatering and potential irreversible root rot. Leggy growth, characterized by stretched stems and widely spaced leaves, points to insufficient light. Burnt spots or discoloration on the leaves suggest too much direct sun exposure, requiring a move to a location with more indirect light. Common pests like mealybugs, identified by fuzzy white spots, can be treated by isolating the plant and gently dabbing them with rubbing alcohol.
