Characteristics: Shrub 0.5-3 metres
Seed per packet: 20
An attractive small shrub with long heads of bright pink rose pea shaped flowers 2 cm long occurring from July to October in its native range.
Can be variable in size depending on conditions but typically grows to around 1 metre in height with mid green heavily divided leaves arranged sparsely along the stems.
Endemic to the Pilbara region of Western Australia.
Prefers a light to medium well-drained 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 18-24°C
Swaisona seeds germinate readily, however they do have a hard outer coating which is impervious to water. To assist in the uptake of moisture for germination to occur seed best scarified bypre-treating with hot water.
Hot water treatment is recommended for this species.
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.
