Black-eyed Susan Vine 'Susie'

Thunbergia alata 'Susie' | Rating: 0 votes | Print / Pdf

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.
