This specimen boxwood has grown in Bonnefont Garden for fifteen years or so and is three and a half feet tall. Although we are accustomed to seeing boxwood used as a low edging for formal garden beds, as it has been since the sixteenth century, the arborescent form of the species can attain a height of twenty-five feet. There are many horticultural varieties of Buxus, including dwarf forms and variegated forms. B. sempervirens is the common European box of the Middle Ages. Japanese and Korean species of boxwood are now commonly grown in American gardens as well.
