English Name: Black-eyed Susan Vine
Scientific Name: Thunbergia alata
Family: Acanthaceae (Flowering plants)
Black-eyed Susan grows to a height of 1.8 to 2.4 m (~5.9 to 7.9 ft). The vine has twining stems with bright green leaves that are either heart-shaped or arrow-shaped. The flower is typically yellow to warm orange with a black center. It has five petals. The brown fruit is small and looks like the head of a bird, with its rounded based and elongated beak.
Distinct features: 1) the bright green leaves are quite coarse and hairy; and 2) the beautiful flower is hard to miss; it is typically bright yellow but it can also be white, orange or red.
The Black-eyed Susan vine is a perennial, meaning that it will typically live for more than two years. It is pollinated by bees, which carry the pollen to another flower. It is believed that seeds are ejected when the vine’s fruit opens.
Habitat: Tropical evergreen forest.
Distribution: Native to tropical Africa. It is now found in several parts of the world including Saba, Brazil, Hawaii and southern USA.
