Acacia denticulosa
Sandpaper wattle is a spindly, open shrub from south-west Western Australia, grown for its bright golden flower spikes and unusual rough, veined phyllodes. It is fast growing, easy from seed, and needs a sunny, well-drained spot.
Acacia denticulosa, commonly known as sandpaper wattle, is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a spindly shrub with irregularly oval, prominently veined phyllodes, spikes of golden yellow flowers and straight or slightly curved pods.
Sandpaper wattle has horticultural features including its unusual leaves and bright flowers. It is also bird-attracting. All wattles are legumes and hence fix nitrogen in the soil. Readily grown from seed, it is fast growing and can flower within the first year. Flowering can last until early summer in cultivation. It requires a sunny aspect and good drainage, though might not adapt well to areas with humid summers.
Sandpaper wattle is found in eight scattered populations over a range of 180 km (110 mi) in the Merredin district in the Western Australian Wheatbelt northeast of Perth, over an area roughly bounded by Nungarin in the south, Wongan Hills in the west and east of Mount Churchman in the east. It generally grows on or near granite outcrops, and occasionally on sandplains, or a range of soils such as silt, clay, loam or sand.
