One of the most effective ways to make a patio and garden feel cooler is to surround it with the right plants. It's not a substitute for an air con unit, but leafy trees, vigorous climbers and moisture-loving foliage plants can help create a cooler microclimate by providing shade, reducing reflected heat and releasing moisture into the air.
For this reason, some of the best plants for cooling a patio combine height, dense foliage and large leaves. They create dappled shade, absorb heat and some even have beautifully scented flowers.
