Potato Vine Blue A new and very pretty cultivar of potato vine, suitable for smaller gardens, Solanum jasminoides Blue is a large, vigorous, scrambling, very long-flowering climber, whose wiry stems need to be tied into a support. The small, ovate leaves are a deep, glossy green with a purplish flush. From June to September, and often into October, masses of mauve-flushed, white, five-petalled flowers with a pointed, yellow-orange centre emerge from mauve buds. Not for the coldest or very exposed areas, it's best grown against a warm, sunny wall. Also known as Solanum laxum Bleu.
