Buxus - North Star Boxwood

North Star is superb cold hardy Boxwood with a dense globe shape that requires little if any pruning. It's a beautiful evergreen that will provide four seasons of enjoyment in the landscape. Easy to maintain to desired size, use it as a low-mounded specimen, or form a low-growing, dense, thick hedge, or even create the borders of a formal herb garden. Either way you won't have to do much pruning to get a full, dense plant. Add it to any garden for winter interest; the shiny dark green leaves maintain great winter color. Evergreen.
