The thick silver-grey velvety leaves of Plectranthus argentatus make it a perfect foil when planted with dark leafed plants or strong contrasting flowers.
Plectranthus argentatus ‘Silver Shield’ is a native of Australia and therefore, is not hardy in this country, where it is best grown as an annual bedding plant or in a large container. It does not require full sun and is drought tolerant.
The flower spikes produced in early autumn are fascinating, growing up to 20 cms long, and covered in a multitude of tiny flowers, each one just a centimetre high and resembling a miniature orchid. Some people prefer to pinch out the flower spikes when grown for foliage alone, but I rather like them.
The young foliage has the most attractive colour, so it is best to raise new plants by taking cuttings. Overwinter cuttings in a greenhouse or keep indoors as a houseplant and take cuttings next spring.
Plectranthus argentatus ‘Silver Shield’ grows approximately 60 cms high and wide.
