The structure is in place, the planting is not
Where the hard landscaping is already built, or already designed by someone else, the planting design works within the structure you have. Nothing needs to be dug up for the garden to change completely.
This is Planting by Numbers. Every plan is drawn to be followed by whoever does the work: each plant named, positioned and counted, so you can easily follow it yourself or hand it to a gardener without translating anything.
