The Dwarf thunbergia (Thunbergia natalensis) belongs to Acanthaceae (the Acanthus family). It is an evergreen shrub that is distributed from the eastern Cape region of South Africa to KwaZulu-Natal, Swaziland and Zimbabwe. It grows in bushes and grasslands on the edge of forests and is about 1 m high. Since it is a rainy area in summer, it sleeps in the dry season in winter. Thin stems emerge from the base of the wood, and ovate to elliptic leaves are opposite. During the summer, the pale blue to mauve tubular flowers come in bloom. The center of the corolla is yellowish white. The species name is associated with the Natal region of origin.
