Small patches of tropical rainforest in Tanzania’s Eastern Arc range provide home to a rich assortment of plants, many of which are found nowhere else in the world. These include the Usambara or African violet (Saintpaulia) and Impatiens, which are sold as house plants in grocery stores throughout the West. Similar forest patches – remnants of the much larger tropical forest that once extended across the continent – are also found in the Udzungwas, Ulugurus and several other areas. South and west of the Eastern Arc range are stands of baobab, with some particularly striking baobab-studded landscapes in Tarangire National Park.
Away from the mountain ranges, much of the country is covered by miombo (‘moist’ woodland), where the main vegetation is various types of Brachystegia tree. Much of the dry central plateau is covered with savanna, bushland and thickets, while grasslands cover the Serengeti plain and other areas that lack good drainage.
Amani Nature Reserve and Kitulo National Park are among the country’s botanical highlights, and Kitulo is one of the few parks in Africa with wildflowers as its focal point.
