Known in England as nine-pin heath, this slow-growing, long-lived, robust, well-branched shrub can reach 5 feet high and 6 feet wide. It clothes itself in small dark-green linear leaves, arranged in whorls of four to six.

What makes this South African species particularly interesting is that it boasts one of the broadest range of flower colors in the genus. The 1/2- to 1-inch tubular flowers – borne in dense, spike-like inflorescences up to 10 inches in length at the tips of main branches – range from orange-red, purple, dark red, greenish-cream and white, to various shades of pink. These bright flowers (some almost seem as if they’re lit from the inside) can be found throughout the year, but are concentrated in the fall and winter periods.

Ericas are multipurpose shrubs. They’re wonderful winter companions to other cool-season, drought-tolerant blooming shrubs such as correas, grevilleas and verticordias. They work well in a mixed bed, adding bright green textures and a splash of color to sunny beds. Low-growing species provide a verdant contrast to succulents in a dry garden plot, and they can even be used as a shrub border. Smaller species can be grown in pots to showcase their winter display.

Striking ericas

Here are a few more impressive ericas: E. darleyensis ‘J.W. Porter’ sports dark green foliage tipped red and cream in spring and purplish-pink blossoms; E. ventricosa (wax or porcelain heath) has elegant urn-shaped, blushed pink flowers that taper to a narrow throat and whose lobes curl backward to form a star; E. speciosa makes a great 3-by-3-foot landscape shrub, and its yellow-tipped rosy flowers appear over a long season. E. glauca’s calling cards are its enlarged red bracts and calyxes that envelop the burgundy globe-shaped corolla like a flamenco dress and E. canaliculata, a 6- to 8-foot-tall shrub, bears masses of small pink flowers with maroon-black centers in winter and spring.

Cultivation

Grow in full sun, in fast draining acidic soil. Ericas can tolerate poor soils but are not happy in our clay soil so if that’s what you have, amend with pumice, sand or other humus materials. Pruning group 10. Zones 8-10 depending on the species.

Pests & diseases

Verticillium wilt, root rot and powdery mildew may be problems.
