Japanese holly plants (Ilex crenata) grow into dense, rounded bushes between 3 and 10 feet tall and wide, with lustrous leaves and a compact habit. Some grow slow and some relatively fast, so pick your cultivar carefully. The shrubs offer small greenish-white flowers in springtime but they are neither fragrant nor showy. The blossoms turn into black berries over summer. These holly shrubs resemble boxwood plants and, like boxwood, make excellent hedges. You can also use small-leafed holly species like Japanese holly as foundation shrubs. Cultivars offer different colors and shapes, so choose something that pleases you and suits your garden.
