From Paraguay and Argentina. As a shrub, it grows to 812 feet tall and 610 feet wide. But it can be staked into a tree form or, with support, grown as a vine to 1215 feet or more. Can also be allowed to sprawl as a ground cover. Leaves are bright green, oval; violet-blue, - to 1 inches flowers throughout warm weather, often nearly year- round. Informal, fast growing, not easy to use in tailored landscapes; prune hard to keep it neat. In severe cold, leaf drop is heavy and branch tips may die back. Not browsed by deer. 'Royal Robe' is more compact (to 68 feet high and wide), bears darker purple flowers over a longer season. 'Variegatum' has green leaves edged in white. Formerly known as Solanum rantonnetii.
