Mr. Bowling Ball Arborvitae (Thuja occidentalis 'Bobozam') is a popular, slow-growing, dwarf evergreen shrub known for its unique, perfectly rounded, compact shape and soft, lacy, blue-green foliage that requires virtually no pruning to maintain its globe-like form. This resilient shrub thrives in full sun to partial shade, making it an excellent choice for rock gardens, borders, and containers, reaching about 2-3 feet tall and wide and offering year-round interest with minimal care, though it's hardy in zones 3-7.
