Acacia rupicola is known as the Rock Wattle. This is an appropriate common name because the species name means “of rocky areas”. The Rock Wattle is a rigid, upright shrub that reaches a height of two metres and has slightly sticky foliage and stems.
Phyllodes are about two centimetres long with a single vein, pungent point (sharply pointed) and a gland near the base. Young foliage and buds are resinous.
Globular flower heads are cream to yellow and appear from August to January with sporadic flowering at other times.
Acacia rupicola is similar to the well-known Acacia ulicifolia (Prickly Moses) group of wattles but is distinguished from them by its sticky appearance.
Acacia rupicola is found in Victoria and South Australia.
The Rock Wattle would be a colourful addition to native shrubberies. Just keep plants away from the borders as the foliage is a trifle prickly.
Propagate from seed and cuttings.
The type specimen was collected in the Marble Range, southern South Australia.
