The Hardenbergia genus is a member of the pea flower subfamily of the legume family. There are three species in Australia that grows in areas from Queensland to Tasmania. For a hardy, evergreen, twining, woody-stemmed climber, which has dark green leathery leaves with a mass of dark purple pea flowers Hardenbergia is a perfect choice. This wonderful Australian native plant is also known as False Sarsaparilla or the Purple Coral Pea. This plant mostly prefers a sunny or semi-shaded position and flowers better in full sun but it needs well-drained soil. Hardenbergia preferably likes a frost-free site, although it is tolerant to some frost. Like most other evergreen climbers, it has a tendency to run up a wall or fence. For compact growth and an even fence coverage, it requires pruning regularly after flowering.
