The common concept is Formal garden style , it has less maintenance and long view you can create fully green. When I was surfing on net I sow French formal gardens design such as it’s awesome look and interesting long view them design by French garden planner as will as in garden winding paths surrounded by gardens of natural. It’s fully commercial look in formal garden. I think it’s very old ideas just them modified and expressed by different designs. There are still thoughtfully layed out walks and paths to enjoy, with flower plantings of seemingly free formed planting.
