Gollum is a named cultivar of Crassula ovata. Its fleshy leaves are elongated and nearly tubular, with distinctive cup-like ends. [4][2]
The foliage sits on branching succulent stems that become woody with age. The plant combines the familiar jade-tree habit with an upright fan of finger-like leaves. [4]
An ordinary indoor room suits jade. A daytime range around 60–70°F / 16–21°C is a useful growing target, with cooler nights. Protect the plant from freezing. [7]
Ordinary dry indoor air suits succulent growing. Keep the plant in a ventilated position and care for the roots through drainage and measured watering. [8]
Check for crowded roots and an unstable, top-heavy plant before choosing a new container. Repot as fresh growth starts. [5]
Move to a slightly larger draining pot, support the plant upright, and settle fresh succulent mix around the root ball. [11]
Water sparingly while the repotted plant establishes, then return to a drying cycle suited to its pot and light. [5]
Persistently wet succulent roots can rot, and overwatering can lead to leaf loss. [10]
Underwatering and damaged roots can both leave succulent foliage shrivelled. [10]
Jade plant is toxic to cats and dogs. ASPCA lists it under the synonym Crassula argentea; signs include vomiting, depression and poor coordination. [13][1]
After suspected ingestion or signs of illness, contact your veterinarian or ASPCA Poison Control at 888-426-4435. Provide the plant’s botanical name. [14]
Keep the plant, cuttings and loose potting material beyond young children’s reach. Display it as an ornamental plant and keep plant material away from food and drinks. [15]
For a human plant ingestion in the United States, call Poison Control at 1-800-222-1222 or use webPOISONCONTROL. Elsewhere, contact your local poison service. [16]
