This popular plant is an evergreen shrub. It will keep its small green leaves all year round. Japanese varieties grow to be about 3-4′ tall and don’t need to be pruned. They only grow about 1-3″ a year. They don’t lost their form, unless you want to change from a rounded form to a square form. They like full sun to light shade. Boxwoods are great for hedges and lining walkways.
