Solanum jasminoides, or the Potato Vine is a twining climber that bears a profusion of white flowers in spring and summer.
It has deep green leaves that will provide dense cover when grown in full sun, but it's the white, star-shaped flowers that have made this such a popular climber for Australian gardeners.
It can be trained on a trellis, pool fence or pergola, wherever there's a support.
N.B. It can be deciduous in colder climates and tends towards thin foliage cover if there is too much shade.
