Erica cerinthoides

A small, erect shrub with an open habit, growing to 1.5m by 1m wide.

In late winter this stunning Erica produces clusters of tubular bright orange/red flowers on the end of long green stems. The branches can be straight or arching and are covered with whorls of linear grey-green finely haired leaves.

They require moist to well-drained acidic soils (ideal pH between 5.5 and 6.7) and a sunny position. They are hardy but will be damaged by severe frosts.

Young plants are easier to establish than larger ones. These plants will grow quickly when planted in autumn when soil is moist and warm. Erica do not like their roots drying out; add compost (avoiding manure and lime) to help water retention. Always choose healthy, well-grown plants. Shrubs may be planted at any time throughout the year, provided they are watered during dry periods. Planting success is often improved on clay soils by adding extra topsoil and forming raised beds. Incorporate coarse sand, bark and compost to improve soil structure. Before planting, ensure that the root ball is saturated and remove planter pot with minimal root disturbance. Trim any broken roots or branches and plant at the same level as in the container. Long term, slow-release fertilisers may be added at this stage. As soil is placed in the prepared, hole tread firmly to bring soil in close contact with the root ball. Water thoroughly, making sure that moisture penetrates to the depth of the root ball.

Young plants require thorough watering during dry periods. Mulching conserves moisture and suppresses weeds. Prune plants after flowering to keep them compact and promote growth of next season’s flowering wood.

Feeding is essential for plant maintenance. Controlled-release fertilisers that release nutrients on warm days in the presence of water (e.g. osmocote or horticote) have proved effective, provided they are low in phosphates. Follow instructions provided with the product or apply 20 - 30 granules per plant in autumn and spring. Kelpac is also useful as a root growth stimulant. Ericas do not like their roots drying out, so add compost to help water retention (avoid manure and lime).

Slow-release fertiliser is recommended, as using a liquid fertiliser can add too much nitrogen which encourages leaf growth but not flower production. The root ball sometimes dries out despite the surrounding soil being moist. When this occurs, directly water down the plant stem to saturate the root ball. The first summer and autumn after planting is critical for young plants; water thoroughly during dry periods. A good mulch containing citrus peel will add some acidity. Keep mulching material away from plant stems.

The showy red flowers will attract bees and bird pollinators to the garden.

Usually pest and disease free.

Erica cerinthoides is named after the genus Cerinthe the honey wort because of the similarity of the flowers and their arrangement. Francis Masson first introduced Erica cerinthoides into cultivation in England and it featured in the Botanical Magazine in 1794. It was a favourite species in cultivation at that time but is seldom seen in cultivation these days.
Erica cerinthoides is the most widely distributed of the heaths in southern Africa. It is found in different habitats in the Cape where it grows from the coastal plains to the mountain tops.
