About Mr. Bowling Ball Thuja

Arborvitae are common ornamental shrubs. The specimen Mr. Bowling Ball arborvitae has curved appeal that needs no pruning to keep it in true form. This charming shrub is a rounded ball-like plant with a perky appearance and compact shape. While not readily available at many nursery centers, the plant is easy to order from online catalogs.

What’s in a name? This arborvitae is also known as Bobozam arborvitae. Thuja occidentalis ‘Bobozam’ is a cultivar of American arborvitae, a native shrub to North America. It has a naturally dense form that is a dwarf of the native shrub. The plant matures up to 3 feet with a similar width.

The bright green, evergreen foliage swirls around the balled form and is softly lacy. The almost unnoticed bark is gray with rusty red furrows. Bobozam arborvitae grows so close to the ground that the foliage mostly covers this classic bark of the false cedar family. Tiny cones appear in late summer but are of little ornamental interest.
