“Peter on a Platter” is the common name for the distinctive succulent Aichryson tortuosum. This plant is recognized for its rosette-forming growth habit, which creates a stacked or tiered appearance.
Unique Peter on a Platter Characteristics
Aichryson tortuosum is a densely branched succulent shrublet, typically growing up to 6 inches (15 cm) tall. Its woody branches are often described as tortuous or twisting. The plant features fleshy, obovate leaves, usually green, which can develop purplish-red edges when exposed to bright light or mild stress. These leaves are covered in glandular hairs, making them slightly sticky.
The leaves grow in tight rosettes that stack vertically along the stems. In late spring or summer, Aichryson tortuosum produces clusters of star-shaped flowers with deep yellow petals. This plant is native to the Canary Islands, where it grows tucked into crevices on volcanic cliffs, which explains its preference for well-draining conditions.

Light Needs
Aichryson tortuosum thrives in bright, indirect light. Indoors, position it near an east or west-facing window with filtered light to provide ample illumination without harsh direct sun. Morning sun is tolerated and can enhance reddish hues in its foliage. Avoid intense afternoon sun, which can scorch leaves. Insufficient light leads to leggy growth.
Watering Schedule
Water Aichryson tortuosum using a “soak and dry” method to prevent root rot. Allow the soil to dry out completely between waterings before rehydrating thoroughly. Overwatering can lead to mushy or yellowing leaves and root rot. Adjust watering frequency seasonally; the plant needs more water during its active growing season in spring and fall and less during summer dormancy. Shriveled leaves indicate underwatering.
Soil and Potting
Well-draining soil is crucial for Aichryson tortuosum. A cactus or succulent potting mix, often amended with perlite or pumice, is suitable. Using pots with drainage holes is important to prevent water accumulation and root issues. Repotting is needed when the plant becomes root-bound and should be done gently, ideally in the spring.
Temperature and Humidity
Aichryson tortuosum prefers average room temperatures during its active growth, between 68°F and 77°F (20-25°C). It is sensitive to frost and must be protected from freezing conditions. The plant may go dormant during hot, dry summer weather. It prefers low humidity environments. Placing the plant away from heating appliances during winter helps prevent excessive drying and leaf drop.
Fertilizing
Fertilization for Aichryson tortuosum should be sparse. Use a diluted, balanced liquid fertilizer formulated for succulents. Apply during its active growing season, typically from spring through summer, to stimulate growth. Avoid fertilization during dormancy to prevent burning roots. Over-fertilization can harm the plant.
Propagating Peter on a Platter
Propagate Aichryson tortuosum using stem or leaf cuttings during its active growing season (spring and summer). For stem cuttings, select a healthy stem 2-3 inches long and cut just below a leaf node. For a leaf, gently twist a healthy, plump leaf from the base, ensuring a clean break.
Allow cut ends to “callus” or dry for two to three days in a dry, shaded location to prevent rot. Once callused, plant stem cuttings about an inch deep into a well-draining potting mix. For leaf cuttings, place the callused end directly on top of the soil. Provide warmth and bright, indirect light, and water sparingly until roots establish and new growth appears.
Troubleshooting Common Issues
Leggy growth, characterized by stretched stems and widely spaced leaves, indicates insufficient light. Move the plant to a brighter location with indirect sunlight to promote compact growth. Mushy or yellowing leaves signal overwatering, which can lead to root rot. To address this, reduce watering frequency and ensure the soil is completely dry between waterings.
Conversely, shriveled leaves point to underwatering, indicating the plant needs more consistent moisture. Common succulent pests like mealybugs (white, cottony masses) and aphids (small, pear-shaped insects) can affect Aichryson tortuosum. Treat pests by wiping them off with a cotton swab dipped in rubbing alcohol or applying an insecticidal soap, repeating applications until gone.
