Plectranthus 'Silver Shield' is one of those plants we wouldn't be without, for we love the lovely mounded habit, the substantial quilted leaves covered with silvery down, and the subtle tints of mauve on the stems, leaf-backs, and flowers. Pale rose flowers of tobacco, and pink dahlias mingle effectively, and it effortlessly creates a harmonious whole from a jumble of discordant hues in the garden.
