What is Stonecrop?
Stonecrop (Petrosedum) is a easy-care plant from the Crassulaceae family. Petrosedum is a genus of hardy, mat-forming stonecrops segregated from Sedum, including the popular blue and Jenny stonecrops (such as P. rupestre). These evergreen succulents form low spreading carpets of needle-like blue-green to golden foliage and lift bright yellow star-shaped flowers on short s...
Stonecrop grows up to 30cm, spread of 60cm, watering every 18 days, -34°C â 38°C, 20â50% humidity. It is suitable for indoor environments and safe for pets.
Unlike many tropical plants, Stonecrop tolerates watering mistakes. Best for beginners. Unlike many popular species, Stonecrop is safe to keep around pets. Without adequate drainage, root rot can develop within 36 days.

What Diseases Commonly Affect Stonecrop?
TLDR: Stonecrop is susceptible to 5 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
Endurance, tranquillity and resilience â a plant that thrives on bare rock where little else can.
Fun Facts
Petrosedum was split from the huge genus Sedum, grouping the wiry, rock-dwelling alpine stonecrops together.
Detached sprigs root so easily that a dropped fragment will often start a new plant on its own.
