The Black-eyed Susan vine (Thunbergia alata) is a frequent sight in hanging baskets and as easy to care for as it is charming. The flowers look daisy-like at a distance, with five over-lapping, solid-colored petals surround a brownish-purple center tube. The medium green leaves grow opposite one another and can be either heart-shaped or have a lance-like arrowhead shape.
This fast-growing vine is best planted in the spring once the soil has warmed. It is most commonly grown as an annual and can extend to 8 feet in one growing season.
