The RHS Wisley Garden in Surrey is one of the world's greats, packed with endless horticultural inspiration. The stunning Mixed Borders are probably the most iconic and celebrated area of the garden. Originally designed by horticulturist Graham Stuart Thomas, the borders are 128m long and 6m wide and backed by hornbeam hedges. The beautiful Laboratory building is a must-see.
