Common name: Black-Eyed Susan Vine
Botanical name: Thunbergia alata Family: Acanthaceae (ruellia family)
Black-eyed Susan vine is an perennial climber native to South Africa. Grown in
tropical zones it will climb to 8 feet but stays much smaller when grown as an
annual or when it is contained in a pot. Orange or yellow flowers have
chocolate-purple centers and are produced in mid-summer until autumn.
This annual is available in whites, creams, yellows and gold, and is usually
started from seed. The Black Eyed Susan Vine is not nearly as aggressive nor
as hardy as Thunbergia gregorii, but has much the same fuzzy wrinkled leaves
and tendrils. The flowers look very striking due to the dark center and will
be covered in bloom most of the year, excepting the depths of winter.
