WHY SILVER?

Nearly all plants with silver foliage originate in hot, dry, windy places, and have adapted to cope with the extremes of heat and drought. Their light-coloured leaves reflect the sunlight, and many are insulated by fine hairs or a waxy coating, which can also appear on buds and branchlets. These adaptations act as insulation, enabling the leaves to conserve moisture, and also help them cope with salty winds.
