Plectranthus argentatus, commonly known as Silver Spurflower, is a semi-deciduous shrub in the mint family, native to Australia, particularly in rocky sites and dry scrub areas of Queensland and New South Wales. It typically grows to 1 m (3 ft) tall and broad, with a spreading habit. The plant is notable for its striking silvery-grey foliage that is velvety to the touch due to a dense covering of fine hairs. From late summer to fall, it produces bluish-white flowers on terminal racemes up to 30 cm (12 in) long, which are moderately showy and attract pollinators.

Silver Spurflower is valued for its attractive foliage and is used as an ornamental bedding plant in temperate regions. It is also suitable for container gardening and can be used in coastal gardens due to its tolerance of sea breezes. The plant is easy to propagate from cuttings, making it a convenient choice for gardeners. It has earned the Royal Horticultural Society’s Award of Garden Merit, reflecting its desirability for cultivation. In terms of care, Silver Spurflower thrives in part shade but can tolerate full sun in cooler climates. It prefers medium amounts of water and well-drained soil. While it is generally pest-free, it can be susceptible to mealybugs and spider mites under certain conditions. It is not known for aggressive roots or significant disease problems.CC BY-SA 4.0
