A Little Silver Does It

"Cast of silver" (Plectranthus argentatus) adds sparkle to a flower garden. One foot in height, three feet in width, Cast of silver creates a striking background for low-growing annuals and perennials. Beneath an overlay of silver hairs, its leaves are a light, fuzzy, gray-green which grow two-to-five inches long with scalloped margins. Stems and leaves are overspread with a purple cast. In addition to the striking foliage, summer brings lavender flowers which look striking next to salvias and buddleias. Cast of silver can be grown in sun or partial shade in well-drained, moderately fertile soil. Plants mature rapidly in about three months.
