If you need height, but are short on space, try Green Tower Boxwood. A tall column-shaped Boxwood, it can reach up 9′ tall but only 1-2′ wide. Evergreen foliage emerges pale green before maturing to a shiny deep green. Great for topiaries, containers, formal plantings. Only reaching 1-2′ wide makes this perfect for small spaces where height is still needed. Inconspicuous yellow flowers bloom in spring.
