Origin and Habitat: Garden origin (Nursery produced cultivar). The original natural habitat of this species is the eastern Cape in South Africa, also in KwaZulu-Natal and Mozambique.

• Crassula cv. Gollum
• Crassula ovata cv. Gollum
• Crassula portulacea cv. Gollum

Description: The Crassula cv. 'Gollum' is a very compact shrubby succulent-plant upt to 60-90 cm tall and 40-60 cm wide with interesting tubular leaves that have a reddish tint. Itconsidered by some a hybrid of Crassula ovataSN|18612]]SN|18609]] (portulacea). (but others suppose it may be a cross between Crassula argenteaSN|18609]]SN|18612]] and Crassula lactea). This is a similar cultivar to the earlier Jade cultivar 'Hobbit' but where 'Hobbit' leaves are curled back around, while the cultivar 'Gollum' has leaves that are nearly tubular and appear to be tipped with a suction cup reminiscent of the J.R.R. Tolkein character by the same name. Both 'Gollum' and 'Hobbit' are interesting plants with trunks that becomes thick with age and developing interesting stem patterns. This two cultivars has been considered to be identical and people confused one to each other and now plants in the the trade and collection are variously and often improperly named. But whatever named, it's a nice variation on the jade.
Habit: It is a small sparingly branched, shrubby, erect, succulent, that can slowly grow up to 50-80 cm tall by 30-60 cm wide.
Stem: It has a stout succulent, almost caudiciform, segmented, branching trunk, it can be shaped to create spectacular bonsai forms.
Leaves: Tubular, trumpet shaped, each of them tipped with a "suction cup", 4-ranked (decussate), smooth, deep glossy green in color with very light spotting usually with bright red leaf margins; the new growth is red.
Flowers: In clusters, small, star-like, white or pinkish-white, with pink stamens.
Blooming season: Late autumn to early winter.

Cultivation and Propagation: Crassula 'Gollum' is great for container culture and Bonsai cultivation, and the trunk becomes very thick with age and develops interesting patterns. Young plants will quadruple in size in one year only. It need full sun to partial shade and a well-drained soil mix. In the greenhouse use a very draining compost. Plants should be well watered and allowed to dry thoroughly before watering again. Fertilize them once during the growing season with a balanced fertilizer diluted to one half the recommended strength. Must over-winter in greenhouse or indoors (with lots of light). During the winter months, plants are watered only enough to keep the leaves from shriveling. The most common reason for failure in growing these plants is overwatering. Seldom has any diseases only the mealy bugs like it, and tend to attack around the primary flowering time (winter to early spring), hardy to -1° C.
Propagation: It is propagated by leaf and stem cuttings. Offsets are readily available and cuttings roots easily, it also propagate by leaf-cuttings and often leaves fallen/broken off will self-sow at the base.
