BLACK EYED SUSAN VINE , Starter Plant (Thunbergia PINK)

Large velvety blossoms have unique indented centers and shades of rich rose pink. A summer-long show of flowers is yours, for it really comes into its own in high summer in fertile, humus-rich soils. A touch of afternoon shade is welcome where heat is unrelenting.

The black-eyed Susan vine (Thunbergia) is a frequent sight in hanging baskets at the garden center. This flowering vine is as easy to care for as it is charming. The flowers look daisy-like at a distance, with five overlapping, solid-colored petals surround a brownish-purple center tube. The medium green leaves are a little coarse and grow opposite one another—they can be either heart-shaped or have a lance-like arrowhead shape.

This vine is native to eastern Africa and grows as a perennial in tropical climates. It is considered an invasive species in much of the world, including in the state of Hawaii. If you live in plant hardiness zones 10 or 11 and wish to grow black-eyed Susan vine outdoors, check with local authorities to make sure it is not invasive in your area.

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.
