Erica abietina is a species of erica that is endemic to the Cape Peninsula of the Western Cape, South Africa .[1] E. abietina includes four subspecies with often highly restricted distributions and distinctive flower colours. Previous delimitation of the species has included a further three subspecies[2] which proved to be more distantly related to Cape Peninsula endemic E. abietina subspecies and are now classified under Erica grandiflora L.f. (Erica abietina subsp. aurantiaca E.G.H.Oliv. & I.M.Oliv.; Erica abietina subsp. perfoliosa E.G.H.Oliv. & I.M.Oliv.) and Erica situshiemalis E.G.H.Oliv. & Pirie.[1]
Subspecies
- Erica abietina subsp. abietina (or the red heath) is restricted to the Peninsula Sandstone Fynbos on Table Mountain, Cape Town. It produces rich-red flowers and grows up to about 1.5 metres (4 ft 11 in) in height.[3]
- Erica abietina subsp. atrorosea E.G.H.Oliv. & I.M.Oliv. (or the wine-red heath) is found only in the southern parts of Peninsula Sandstone Fynbos on the Cape Peninsula, Cape Town. It produces pinkish-purple flowers and grows up to about 1 metre (3 ft 3 in).[4]
- Erica abietina subsp. constantiana E.G.H.Oliv. & I.M.Oliv. (or the Constantiaberg heath) is restricted to the Peninsula Sandstone Fynbos in the middle of the Cape Peninsula between Constantiaberg and Chapmans Peak. It forms a small, dense shrub with bright pink flowers.
- Erica abietina subsp. diabolis E.G.H.Oliv. & I.M.Oliv. (or the devils heath) Critically endangered
This plant grows very easily and well in urban capetonian gardens and is increasingly popular as an ornamental plant.[5]
