Erica cerinthoides aka Honeywort Flowered Heath

Erica cerinthoides, or fire heath, is an evergreen shrub. It belongs to the heath family, Ericaceae. Its native range covers parts of southern Africa. These include South Africa, Lesotho, and Eswatini. In South Africa, records span the Cape, Free State, KwaZulu-Natal, and Transvaal. Wild plants grow on dry flats and in mountain sites. The species is not native to Britain or Ireland.

This bushy shrub reaches about 3.3–4.9 feet [1–1.5 metres] tall. Its mature spread is about 1.6–3.3 feet [0.5–1 metre]. Plants take five to ten years to reach full size. Fine hairs cover the narrow, needle-like leaves. Each leaf measures about 0.02–0.03 feet [0.006–0.01 metres] long. The plant keeps its leaves through the year. Its tube-shaped flowers are most often red-orange. Some plants bear pink or white blooms instead. The flowers hold abundant sweet nectar.

For cultivation, the RHS advises acid soil and full sun. Its growing conditions table also allows neutral soil and partial shade. Loam or sand can suit this shrub. Soil should drain well while retaining some moisture. Choose a sheltered site facing south or west. Outdoor planting suits only the mildest places in Britain. The RHS rates it H2: it tolerates cold but not freezing. Plants For A Future gives USDA zones 9–11. In colder places, grow it under glass in bright light. Use ericaceous potting compost and keep air moving around it.

Water well during active growth, but less when flowers are absent. Under glass, feed every four weeks during the growing season. Use a balanced liquid feed at half strength. The shrub suits coastal gardens, courtyards, and informal planting. It also works in patio pots and containers. Grow new plants from seed or semi-hardwood cuttings. Plants For A Future reports resistance to fire.

The RHS reports few pest problems with this species. Wet conditions can lead to fungal disease, including Phytophthora root rot. Honey fungus is a less frequent risk. Plants For A Future records nectar as its edible part. People suck the flowers to obtain it. That source lists no known hazards or medicinal uses. This does not establish that every plant part is safe to eat.
