Coastal Brides-bush

Pavetta natalensis, the coastal brides bush or Natal brides bush, is a flowering shrub or small tree in the family Rubiaceae native to the subtropical coastal forests, forest margins, and coastal thicket of KwaZulu-Natal province in South Africa. The genus Pavetta is characterized by conspicuous, often fragrant white flowers produced in dense terminal corymbs, and the showy displays have given many species in the genus the common name brides bush, as their flowering recalls a bride's bouquet. Pavetta natalensis typically reaches 2–6 meters in height and is found in sand forest, dune forest, and coastal scrub habitats where it grows in the sheltered understorey or along forest edges. The white flowers are tubular with a projecting style typical of Rubiaceae, and attract butterflies, bees, and hawkmoths. Fleshy black fruits are subsequently produced and consumed by a range of frugivorous birds that disperse seeds throughout coastal forest habitats. The species is classified as Least Concern by the IUCN, being relatively common in suitable habitat along the KwaZulu-Natal coast. The Rubiaceae family, to which Pavetta belongs, includes the economically important coffee plant (Coffea arabica), making it one of the world's most significant plant families.
