Slender vigorous twining climber that make quite an impact in late winter and early spring when in flower.
Blue to purple pea shaped flower occurring profusely in long dense clusters in spring. Great for covering banks, training over fences or to hide any eyesore in the garden.
Endemic to Western Australia.
Prefers a light to medium soil in an open sunny position, drought and frost resistant.
Although seed can be sown most of the year in Australia seed is generally best sown in spring or autumn in temperate climates, avoid 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 which 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.
