Silver-foliaged plants are mainly planted because of their functionality – they are mostly heat and drought tolerant due to hairy or waxy leaf surfaces and their ability to reflect sunlight and prevent water loss. But there is another reason to fill your garden with a lot of silver-foliaged and grey leaved plants and to combine them with light yellow, cream and white flowers – fashion!
Extend the time you spend in your garden by planting a ‘moonlight’ look with plants that don’t disappear in the dark, but rather come to the forefront. We picked out some stalwart silver-foliaged plants to create that magical, mystical atmosphere by the light of the full moon.
