Black-Eyed Susan Vine (Thunbergia alata)

Not to be confused with the perennial Black-Eyed Susan (Rudbeckia), this is a tropical, fast-growing annual vine that produces cheerful, five-petaled flowers in yellow, orange, cream, or apricot with a distinctive dark center. It adds vertical color and soft texture to trellises, hanging baskets, and containers.
