Plectranthus argentatus, Silver Spurflower, is one of the most arresting-looking of all the Plectranthus with stunning silver foliage covered in soft velvety hairs. It has a semi-erect or sprawling, multi-branched habit and grows vigourously throughout the growing season creating an impressive expanse of silvery-green heavily-textured foliage. In late summer it produces many upright terminal racemes of pinkish-purple buds that open from the bottom to small white spur-like flowers. The inflorescence gives a colourful counterpoint to the leaves but this is a Plectranthus that one grows predominantly for the stunning foliage

Plectranthus argentatus is tender in the UK and while it creates a wonderful and very visual summer bedding plant it does need to be brought inside before the first frosts. It can be overwintered in an unheated but frost-free glasshouse under fleece but this is something of a waste of all that gorgeous foliage and it is best to overwinter it as a houseplant where it will thrive until the following season when it can be cut back and planted out again. Its eventually sprawling habit makes it an ideal plant in a high position from where it will hang down gracefully like a waterfall of silvery foliage.
