Senecio barbertonicus


Family : Asteraceae
Common names : succulent bush senecio, Barberton senecio, Barberton groundsel, Barberton coltsfoot, lemon bean bush, finger-leaved senecio


When everything else seems dead and dry on the Highveld, this plant flowers in abundance. The deep yellow flowers are sought after by many insects during a time when few food sources are available.

Senecio barbertonicus is a dense bushy perennial shrub reaching heights of 0.5–1.8 m. It is an evergreen succulent with all plant parts glabrous. Younger stems are green turning brown and woody at maturity. Old stems are brittle and rough due to the persistent leaf bases of old leaves. Leaves are green for 3–5 seasons, succulent, bright to dark green and finger-like: up to 55 mm long and 5 mm in diameter, cylindrical, slightly curved and narrowing to a pointed tip, with 3–4 nerves running along the length of the leaf.

Bush in flower

Flowering stems protrude above the leaves and bear composite flower heads in small flat-topped clusters. Flowers are all tubular; each subtended by an involucre of 8 bracts, which are 11–13 mm long. The sweet-scented bright yellow flowers are up to 8 mm long and 4 mm in diameter.

Close up of flowers

Fruits are 3.5 mm long, cylindrical, ribbed and covered with stiff hairs between the ribs. Pappi are present and consist of numerous bristles, shorter than the flower tubes. The species flowers in winter.

Conservation status
According to the Red List of South African plants (, Senecio barbertonicus is listed as Least Concern (LC).

Distribution and habitat
Senecio barbertonicus grows in rather dry, sandy areas among rock outcrops or clambering over trees and bushes in sand forest, usually in semi-shade. The plant is drought resistant and mildly frost tolerant.

The species is endemic to southern Africa and occurs in Limpopo, Mpumalanga, Gauteng, North-West and KwaZulu-Natal provinces in South Africa; also in Swaziland, Zimbabwe and Mozambique, at altitudes of 35–1 675 m above sea level.

Derivation of name and historical aspects
Senecio barbertonicus belongs to the Asteraceae (sunflower family). Senecio is derived from the Latin word senex meaning ‘old man', pertaining to the grey hairs on the seeds.

Seeds with hairs

Although it does not only occur in Barberton in Mpumalanga Province (South Africa), the specific epithet barbertonicus refers to the original specimen, which was collected near Barberton by a banker and keen plant collector, Ernest Edward Galpin between 1889 and 1892.

Adult Painted Lady butterflies ( Vanessa cardui ) feed on nectar of Senecio barbertonicus – they are attracted by the discoid, sweetly scented flowers.

Uses and cultural aspects
The plant has a short flowering period, but its evergreen succulent nature makes it a useful garden plant as well as an easy to grow indoor pot plant. It is a good addition to a butterfly garden, attracting particularly the Painted Lady butterflies for nectar. Because it is resistant to drought, Senecio barbertonicus is very suitable for water wise gardens.

Growing Senecio barbertonicus

Senecio barbertonicus is easily propagated from softwood cuttings in late spring to summer. Take cuttings of the plant and let them dry for one or two weeks. Plant them directly in the ground or in a pot with well-drained soil. They can be planted in full sun or partial shade. They prefer slightly acidic to slightly alkaline soil, but can also tolerate poor soils. The plant needs moderate amounts of water from spring to autumn. Keep plants dry during winter to prevent them from rotting at the base. Trim them back lightly to maintain a tidy appearance.
