Hardenbergia 'Happy Wanderer' is a vigorous, evergreen, Australian native climber or groundcover known for its masses of vibrant purple-mauve pea-shaped flowers in winter and spring. It's a hardy plant that tolerates a range of conditions, including full sun to part shade, and is relatively low-maintenance. Its ability to scramble over fences, walls, and pergolas makes it a popular choice for covering structures, while it can also be used as a groundcover.
