'Sky Pencil' Japanese Holly may be just the answer for those looking for a narrow hedge or privacy screen. There are no thorns on these small, shiny green leaves nor will berries form, making 'Sky Pencil' a perfect solution when a narrow, vertical, evergreen profile is needed. This Japanese holly adapts well to container planters, and is well suited for garden borders. 'Sky Pencil' is not the fastest grower, reaching six- to eight feet in height and two to three feet in width at maturity.
