Hardenbergia violacea is an attractive climbing plant whose branches twist around supports to climb. Dark, glossy green leaves 75-100 mm in length. Purple pea-shaped flowers occur in heavy pendant clusters in spring.
It is moderately vigorous but rarely causes damage.
Occurs naturally in South Eastern Australia.
Prefers light to medium soil in an open sunny position, drought and frost resistant.
Although seed can be sown most of the year in many parts of Australia seed is generally best sown in spring or autumn in temperate climates, avoiding the coldest and hottest months of the year. The optimum germination temperature for germination is around 18-22°C.
Hardenbergia seeds germinate readily, however, they do have a hard outer coating that is impervious to water and generally, germination will normally not occur unless the seed is scarified by abrading or pre-treated with boiling water first.
General note: Seeds of many natives are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
