Green is great, but variety in foliage is better, and top of the class for me are blue-green leaves, found in, for instance, Festuca glauca, a beautiful blue grass, and eucalyptus. What I absolutely love, though, is Artemisia (wormwood), my favourite being Artemisia 'Powis Castle'. I planted three this year using Beth Chatto's methods for waterwise planting, and they have practically taken over my garden, so do beware and remember that they grow upwards as well as sideways! Another exquisite shade is silver, seen in Senecio cineraria 'Silver Dust' in the picture here, which I planted from seed. Meant to be a tender shrub, mine is still flourishing in temperatures of 5 degrees Celsius after a few frosts. An exquisite evergreen is Heuchera 'Silver Gumdrop', pictured in my previous post - it is of an indescribable shade, almost alabaster.
