Description: Crassula perfoliata is an erect perennials sparingly branched succulent shrubs to about 1.3 metres tall. The plants are among the largest and most striking examples in the genus with large, pointed leaves in opposite pairs. This interesting species is rather variable, some of its varieties having formerly been treated as distinct species. In Crassula perfoliata var. perfoliata the leaves are channelled, 10-15 cm long, arranged in alternating planes, rather erect, grey-green and have a velvety texture. Rounded flat-topped terminal heads of white flowers are produced in summer.
Derivation of specific name: From Latin “perfoliatus,-a,-um” with the stalk growing through the centre of the joined leaf-bases.
Stems: Green, succulent, becoming woody in age, erect, branching from the base. Branches 5-1.3(-1,5) m long, simple or little branched above, covered with coarse, hard and often rounded warts, with old dried leaves not deciduous.
Leaves: (4-)6-10(-15) cm long, (8-913-18(-40) mm broad, decussate, connate at base, simple, ascending becoming spreading, lanceolate to triangular or slightly falcate, green, smooth, upper face flat, channelled at the base, margin acute to towards the apex, truncate lower down, lower face convex, or apparently laterally compressed and scarcely convex on both surfaces, tip acute, mucronate, densely covered with rounded to often irregularly shaped papillae, green to grey, glaucous sometimes with purple spots. The upper leaves degenerating.
Inflorescences: Rounded flat-topped thyrses, hairy, much branched. Peduncle 30-100(-150) mm long 5 mm in diameter, strigose. Bracts leaf-like, lower 10 x 7 mm.
Flowers: Sweet-scented. Pedicels 1 mm long. Sepals 1-3 mm long, triangular-lanceolate, acute, covered with spreading hairs and marginal cilia, fleshy, green or reddish. Corolla tubular,, 3 - 3-6 mm long, tubular below, stellate above fused basally for 1-1,5 mm. Petals becoming recurved, white, not much exceeding the stamens. Stamens with black anthers. Styles subulate. Squamae transversely oblong, 0,2-0,4 x 0,5-0,6 mm, usually emarginate, slightly constricted downwards, fleshy, yellow.
Blooming season: Spring to mid-summer.
Subspecies, varieties, forms and cultivars of plants belonging to the Crassula perfoliata group
- Crassula perfoliata L.: (var. perfoliata) is little branched up to 1.3 m high, with lanceolate leaves erect and channelled above. The flowers are small, white and appear in the summer. Distribution: north of Port Elizabeth to Graaff-Reinet and Willowmore.
- Crassula perfoliata var. coccinea (Sweet) G.D.Rowley: has the red, larger flowers but its leaves are lanceolate-triangular, canaliculate and erect to spreading. Distribution: river valleys between Port Elizabeth and King William's Town.
- Crassula perfoliata var. falcata (J.C.Wendl.) Toelken: (syn: Crassula perfoliata var. minor) has very peculiar grey-green sickle-shaped leaves that are arranged in overlapping pairs along a usually unbranched stem. Flowers are bright red. Distribution: Eastern Cape.
- Crassula perfoliata var. heterotricha (Schinz) Toelken: is smaller (40 cm tall) and branched with erect leaves, has small white flowers appearing in the winter. Distribution: Umtata northwards through KwaZulu-Natal and Transvaal to south-east tropical Africa.
- Crassula perfoliata var. minor (Haw.) G.D.Rowley: is 20-50 cm tall and is rarely branched. The leaves are laterally flattened, falcate, greyish, has larger bright red flowers (rarely , pink or white). Distribution: Willowmore to East London, and north of the Kei River.

Cultivation and Propagation: Crassula perfoliata is a stunning as a container plant, in decorative pots, in courtyards and rockeries, and especially ideal for mass plantings and borders, where its dramatic foliage and spectacular flower heads are shown to their best effect. Attractive and interesting when not in bloom but a show stopper when the white flowers emerge. This plant rises with an upright stem up to 1.3 m high if it be not broken or injured but it requires support the stems being slender and the leaves very weighty.
Soil: It needs well drained soil (standard cactus potting mix).
Waterings: Requires very little irrigation in coastal gardens, irrigate occasionally in hotter inland climates. In pots needs regular wateringsall year, but reduce watering during winter month and apply a balanced liquid fertilizer during the summer months (June, July, August).
Exposure: It grows well in light shade to full sun.
Hardiness: Protected from frosts, but hardy to -5 C for short periods if very dry.
Maintenance: Remove spent flower heads to maintain vigour and bushy habit.
After growing for several years tend to become untidy, and should be cut very short or restarted from cuttings.
Pests & Disease: Aphids, mealy bugs, powdery mildew, fungal leaf spot, stem and root rot if over watered.
Propagation: Leaf or stem cuttings in spring or summer.
