About Agathosma gonaquensis Eckl. & Zeyh.
Agathosma gonaquensis, commonly known as Gonaqua buchu, is a plant species in the Rutaceae family. This species' habitat is restricted to a very small area of the Eastern Cape, South Africa. Per the South African National Biodiversity Institute, it is classified as critically endangered. Gonaqua buchu was once common around Port Elizabeth, South Africa, where it grew in the coastal grasslands and fynbos surrounding the town. Unfortunately, extensive urban sprawl has covered much of its natural habitat, and the species now survives only in two small, fragmented populations. These remaining habitat patches are currently threatened by rapidly spreading alien invasive plants. In terms of appearance, Agathosma gonaquensis is a low-lying, compact, rounded and spreading plant. It produces large numbers of white flowers, and natural oils in its leaves release a pleasant fragrance when the foliage is crushed or handled. It is used in local traditional medicine to prepare a tea that treats colds and hay fever. When grown in gardens, it is notably tough and waterwise. Once fully established, it tolerates both drought and frost. With its striking white flowers and tiny, dense, symmetrical foliage, it is a very attractive ornamental plant for coastal gardens.
