Black-eyed Susan Vine

Thunbergia alata | Rating: 0 votes | Print / Pdf

Loves wall climbing, like an orange Spiderman.

When looking to cover that boring exterior wall with some inviting foliage, it is impossible to go wrong with Thunbergia alata. Better known as the Black-eyed Susan Vine, its flower is similar in appearance to another of the same common name - the Rudbeckia genus - but it can climb walls, trellises and other surfaces. Its thick mid-green foliage comprises a multitude of glossy, furrowed heart-shaped leaves, but its flowers are the real eye-catcher. Emerging in summer, the flowers are bright orange with a distinctive black eye in the centre. The Black-eyed Susan Vine thrives in well-drained soil, and full sun, and its long thin vines can be easily trained.
