|Dwarf and Intermediate evergreen shrubs are excellent used as foundation plantings. Most of the dwarf and Intermediate evergreens are compact and dense growing. They fit well as accents in perennial gardens. Dwarf Alberta Spruce, Emerald Green Arborvitae and Holmstrup Arborvitae are often used in this way. There are several very compact growing Arborvitae and Chamacyparis that can be used as tiny specimen and hedges in and around the perennial garden. Hetz and Little Giant Cedar grow two and three feet tall. Their natural round shape and size adds a touch of whimsy to to flower and evergreen shrub gardens. You might also consider Red Holly, an evergreen that's quite adaptable and easily pruned to keep it within bounds.
Best wishes with your landscape!
