Green gem boxwood is one of the hybrids developed in canada at the famous Sheridan Nursery. These hybrids can withstand very cold temperatures and maintain good color. Green gem has a small leaf and a very full habit making it ideal for many applications. A slow-growing dwarf plant that forms a tight ball measuring about 2' x 2', having very dark green foliage throughout the year, makes an excellent short, formal hedge when planted closely and requires very little shearing to maintain its shape.
