This is Hardenbergia violacea Rosea, also known as Happy Wanderer, Coral Pea, Purple Coral Pea, False Sarsaparilla, Vine Lilac and Pink Climbing Pea Vine. This plant likes to live in the sun to partial shade and is a good choice for an indoor houseplant. The leaves are evergreen and the blossoms are present from late Winter until the middle of the summer. The leaves and possibly the roots are boiled to produce a slightly sweet drink that is rather good. USDA Hardiness Zones 9 to 11
