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 flowers look very striking due to the dark center and will be covered in bloom most of the year, excepting the depths of winter.
