Hardenbergia violacea 'Happy Wanderer' (Purple Vine Lilac) - An evergreen vine that climbs by twining stems to 12-16 feet. Simple, oblong (2-4 inches) leaves clothe these stems. Pinkish-purple flowers with a chartreuse spot in center cascade like small Wisteria blossoms in the winter to early spring. Plant in sun or light shade in hot inland areas. Tolerates and even prefers heavy soil so long as it drains well. Requires little water once established.
