The orange Black Eyed Susan vine features 1 - 2 inch orange blooms, many with black eyes, against large, heart-shaped foliage. It's a fast climber, and it will adorn a rustic gate, mailbox, flagpole base, or trellis with a twining vine, lush foliage and masses of blooms. Thunbergia orange vines makes wonderful privacy screens if they are grown at the base of chain-link fencing.
