Plectranthus argentatus, common namesilver spurflower, is a species of flowering plant in the mintfamily. It is native to rock outcrops and rainforest in the border region of Queensland and New South Wales, Australia. Growing to 1 m (3 ft) tall and broad, it is a spreading deciduousshrub. The hairy leaves are ovate to broad-ovate, 5–11.5 cm long, 3–5.5 cm wide with crenate margins. The hairs give the plant an overall sage green to silvery colour. The flowers are borne on terminal racemes up to 30 cm (12 in) long, and are bluish white.[1][2]
