The Royal Horticultural Society is one of the world’s leading horticultural organisations and the UK's leading gardening charity. Each year the society puts on just about the RHS Chelsea Flower Show to showcase the highest quality horticulture. If you were unable to make it, don’t worry. Here is a selection of the outstanding exhibits of the 2011 show. They will hopefully inspire you, perhaps frustrate you a little (or a lot) that however hard you try your own garden is never going to look like this!
