Following on from last month´s sultry read, let´s look specifically at some 50 plants that fall into the grey, silver, blue category and that you will be able to find here and use if your heat and drought resistant gardens:
Starting big, some of the best trees would be:
Olea Europea, our beloved olive has to be, of course, top of our list. You´ve only to look at them marching across hot dry plains to understand their resistance. An absolute classic and try tea made from the leaves too. Cupressus Arizonica, the Arizona cypress has lovely silvery grey needles and is, probably, the toughest conifer you can buy even happy in salt-laden coastal positions. It will reach some 15m high with a 5m spread. Eucalyptus species are often much maligned but they have their place and a multitude of uses. Throw a few leaves in a bowl of boiling water and breathe in the relaxing and clearing vapour. And, of course, many of the acacia or mimosa family have greyish foliage, especially the lovely acacia baileyana.
