Coastal Dune Wattle
Characteristics: Dense shrub 0.5-2m
Seeds per packets: 30
A dense dome shaped shrub with yellow globe shaped flower heads composed of 7-16 pale yellow flowers on stalks between 10 and 25 mm long. Flowering occurs from late winter to early summer.
The phyllodes (leaves) range from 10-25 mm long and 5-12 mm wide. Flowering from late winter to early summer.
Endemic to the south west corner of Western Australian and also on Rottnest Island in shallow sand. Ideal for coastal gardens.
Well suited to temperate climates and sandy soils. Hardy shrub suited to exposed conditions. Flowers more profusely in full sun.
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.
Acacia 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.
