Protea repens aka Common Sugarbush

Protea repens is an evergreen shrub in the Proteaceae family. Its common names include sugar bush and Cape honey flower. It comes from South Africa’s Cape region. The RHS lists both the Western and Eastern Cape. Kew places its native range in the southern Cape. It grows in a subtropical climate and keeps its leaves year-round.

The shrub grows upright and forms a bushy shape. Its leaves feel leathery. Garden plants reach about 8–13 feet [2.5–4 metres] tall. Their spread reaches about 5–8 feet [1.5–2.5 metres]. The RHS also describes a height of 10 feet [3 metres]. Plants may take 10–20 years to reach their full size. Flowerheads appear from spring into summer. Pale bracts surround them, with pink at the tips. These heads provide flowers for cutting as well as garden display.

Grow this species in full sun, with shelter from harsh exposure. A south-facing or west-facing site suits it. Outdoors, it needs poor soil that drains well. The RHS lists sand, loam and chalk as suitable soils. It also lists acid, neutral and alkaline conditions. The plant can withstand drought, but drainage remains important. Its UK hardiness rating is H3. This suits coastal sites and other mild parts of Britain. Plants For A Future lists USDA zones 8–11.

In colder settings, a greenhouse or conservatory offers another growing option. The RHS also suggests patios, containers and coastal gardens. It fits gardens with Mediterranean or subtropical planting. For pots under glass, use loam, grit or perlite, and peat substitute. The RHS also includes charcoal in the mix. Give plants full light under glass. Water moderately during spring and summer, then reduce watering in winter. The RHS recommends diluted magnesium sulphate and urea in spring and early autumn. Raise new plants from seed or semi-ripe cuttings.

Pests seldom cause trouble, according to the RHS. Honey fungus can occur, though the source describes it as rare. Plants For A Future records nectar as an edible product. People drink it directly or turn it into syrup. That source lists no known hazards or medicinal uses. Its hazard record does not establish safety for pets. The available evidence gives no details about fruit or bark.
