Cultivation Details

Hardenbergia violacea is mainly native to southern and eastern Australia, where it can be found from the temperate zone of Tasmania to the tropics of northern Queensland. It is not very cold-hardy, able to tolerate temperatures falling to around -5°c for short periods when it is fully dormant[].
Prefers a sunny position, but also succeeds in light shade[]. Grows best ins a moist well-drained lime-free soil[], but it is adaptable to most soils[].
Any pruning is best carried out immediately after the plant has flowered[].
An ornamental plant, there are several named varieties[].
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[].
