Repetition, repetition, repetition!
Use and re-use every element of your artistic creation. Make the key shapes work – don’t be shy with vertical lines, and use the arcs of bridges, paths and border edges to maximum advantage. Echo shapes in the planting, perhaps with spires and spikes of colour. Try delphiniums, lupins, campanula, verbascum or foxgloves erupting from a sea of billowing blooms and repeat the colour themes too, for a lavish, layered effect.
Splendid foxglove spires are do ed through the garden to add cohesion
