Wikipedia

Thunbergia alata

Thunbergia alata, commonly called Black-eyed Susan vine, is a herbaceous perennial climbing plant species in the Acanthaceae family. It is native to Eastern Africa, and has been naturalized in other parts of the world. It is found in Cerrado vegetation of Brazil and Hawaii, along with eastern Australia and the southern USA in the states of Texas and Florida.[1]

It is grown as an ornamental plant in gardens and in hanging baskets. The name 'Black-eyed Susan' is thought to have come from a character that figures in many traditional ballads and songs. In the Ballad of Black-eyed Susan by John Gay, Susan goes aboard a ship in-dock to ask the sailors, where her lover Sweet William has gone. Black-eyed Susan is also a name given to another species of flowers - Rudbeckia.

Flowers and leaves of Thunbergia alata

Description

Thunbergia alata has a vine habit, and can grow to a height of 6-8 ft (1.8-2.4 m) in tropical zones, or much less as a container plant or as an annual. It has twining stems with heart or arrow-shaped leaves. The flowers have five petals and appear throughout the growing season. They typically are warm orange with a characteristic dark spot in the centre, although different varieties can be red, orange, red-orange, white, pale yellow, or bright yellow, with or without the characteristic chocolate-purple centre which inspires the common name.[2]
