It is still mid-winter here in Perth, but various wattle species are coming into flower. We saw this one at Minim Cove recently. It is called Prickly Moses (Acacia pulchella) and grows in the southwest of Western Australia from about Geraldton to Esperance.
The plant looks soft and fluffy, but takes its name from those thorny spines along the stems. You will soon notice them if you brush up against the plant as you walk past.
