Drought tolerant or drought resistant plants are those that can withstand prolonged periods of dry weather. They often have succulent leaves or stems and can sometimes store water. Others have fine hairs or silvery colouring of the foliage that cuts down evaporation.
Drought resistant perennials can be used in a highly effective manner here in the UK, provided they are planted in free-draining soil and in a sunny spot. They are ideal for gravel gardens and 'no dig' systems. They dislike heavy clay soil and waterlogging, however.
