Tall Formal Garden Wall Idea
Here's one idea of what you can do with the tall walls of an enclosed formal courtyard garden. Actually these planting ideas will work with most garden walls. While climbing roses growing on trellises are a common sight in many design plans, several planted in mass is most generally confined to formal or rose gardens. And with that, a planting display like this isn't confined to just roses. Most any climate appropriate climbing vine or combination of vines would create a beautiful display.
And for the rest of the garden, aside from a unique shape and tall border wall, this planting arrangement is common in many formal garden ideas. The taller evergreen bordered by evergreen shrubs creates contrast in height, color, texture, and shape.
