Gardening with greys
Plants with grey foliage are often very hardy and are ideal for low water zones. The light coloured foliage reflects the sun’s rays away from the plant, thereby keeping the plant cooler, which in turn reduces transpiration.
With blue-, silvery- or powdery-grey foliage to choose from, you can create a contrast to the existing greenery, an eye-catching impact to foliage and flowers of other colours, and assist in both co-ordinating or delineating various areas of the garden. Most grey foliage plants thrive in hot, dry climates and many do well where little else wants to grow. They usually require very well drained soil and full sun to keep their striking grey colour. Often, the harsher the conditions, the better they thrive. The following are some suggestions of suitable ‘grey’ plants, most of which are endemic to the Eastern Cape.
