--><p>All of the naturalized species of <i>Erica</i>, as well as some others and hybrids, are cultivated, especially in the northeastern and northwestern coastal areas (D. Metheny 1991). Most require acid soils, although E. carnea, <i>E. vagans</i>, and E. ×darleyensis (E. carnea × E. erigena) will accept neutral soils (A. Mikolajski 1997). Over 700 species are endemic to the Cape region of southern Africa; recent molecular phylogenetic studies suggest that the genus originated in Europe, and that the southern African species represent radiation from an ancestor of E. arborea (A. F. McGuire and K. A. Kron 2005).</p>
