Answer: The roundleaf Japanese holly, Ilex crenata 'Rotundifolia', will attain a height of six to eight feet. It has attractive, glossy leaves and will grow well in partial shade. Another good choice is Green Tower Boxwood. Green Tower grows at a moderate to fast rate and is columnar; nine feet tall, one to two feet wide. The foliage is dense and its lustrous dark green leaves have a lighter underside. Green Tower can be a carefree evergreen hedge barrier, and it looks great as a single columnar specimen or in pairs to flank a gate or entry. It adapts well to shearing, and makes a good choice for topiary forms. You can plant practically anytime in the Pacific Northwest. If rainfall isn't abundant you can always supplement with a hose. Provide about one-inch of water per week to your plants and they should become established quickly. Enjoy!
