Cypress trees and lavender edit: Use the cypress trees (Fink's) sprinkle in some Salvia and dwarf blue-green grasses !This bed is also raised! need to make sure to have space between MATURE trees to pull off look!
Keep the garden vertical. That's why it's good to look for shrubs and trees that max out interest as they grow up, not out. Try dwarf varieties for a small backyard, as well as more columnar evergreens (bonus—they boost wintertime interest, too).
Arborvitae (Thuja occidentalis) - mature width, plant 3 to 4 feet apart. Measure the height and width of the largest root ball. Then use spray paint to mark out a trench that is two to three times wider and 2 inches shallower than the root ball.
