Erica mammosa, commonly known as Nine-pin Heath, is an evergreen shrub native to the fynbos heathlands and mountainous areas of the southwestern corner of the Western Cape, South Africa. This species typically grows up to 8 feet tall and equally broad, with a dense, bushy habit. It produces striking flowers that range in color from light pink to orange to bright red, blooming from late winter to early spring. The species name "mammosa" refers to the udder-like shape of the flowers, which are particularly showy and attract various pollinators.

Nine-pin Heath is valued for its vibrant flowers and evergreen foliage, making it a popular choice for ornamental gardens. It requires acidic, well-drained soil and thrives in a sunny, sheltered spot. While it tolerates temperatures down to 32°F, it is not frost-hardy and benefits from protection in colder climates. It has earned the Royal Horticultural Society’s Award of Garden Merit, indicating its exceptional performance in gardens. In cultivation, it is often used in rockeries, heath gardens, and as part of mixed shrub borders. It is important to avoid overwatering and to provide sharp drainage to prevent root rot.CC BY-SA 4.0
