English boxwood is often called the true dwarf boxwood, and creates a hedge border 1 to 2 feet high. The variety "Suffruticosa" has a slow growth rate of only 1 inch per year, producing neatly compact tufts of green foliage to accent a planting bed, fence line or sidewalk. "Elegantissima" is another slow grower, with variegated creamy-white and green leaves, while "Wee Willie" attains a mature 2-foot height and width with little maintenance pruning required.
There are many dwarf cultivars among the small-leaved boxwoods, including "Morris Dwarf" and "Morris Midget," varieties that reach a 1-foot height at maturity. "Kingsville Dwarf" is often termed the smallest boxwood variety because of its exceptionally small leaves and growth habit of 1/2 inch per year. Because of their dwarf characteristics, small-leaved boxwood cultivars are excellent choices for low formal hedges.
Dwarf varieties of Korean boxwood include "Nana," which maintains a 1-foot height but spreads to a width of 3 feet. "Wintergreen" is a hardier choice, with the ability to survive winters in cold climates and retain its green color throughout four seasons.
Several worthy dwarf boxwood cultivars include "Green Gem" boxwood, a compact variety that grows to a height and width of 2 feet, with excellent color-retention during cold winters. "Green Velvet" maintains a 3-foot height and width and does not suffer leaf-burn in cold weather, while "Wintergreen" has dark green color and similar cold weather resistance, but attains only a 2-foot height and width.
