About this plant
Thuja occidentalis 'Bobazam', commonly known as Mr. Bowling Ball, is a compact evergreen shrub prized for its dense, rounded form and finely textured foliage. The soft, thread-like green foliage maintains its vibrant color throughout the year, providing year-round visual interest. Unlike many other arborvitae varieties, this cultivar retains its neat, spherical shape with minimal pruning, making it an ideal choice for low-maintenance landscaping.
'Bobazam' has gained popularity for use in garden borders, foundation plantings, or as an accent plant in smaller spaces. Its tidy growth habit and resilience to different conditions make it an excellent choice for adding evergreen structure and texture to the landscape. While it doesn't produce conspicuous blooms, its consistent form and lush foliage make it a valuable ornamental shrub.

Design tip
Repeat Mr. Bowling Ball at intervals to create rhythm without the stiffness of clipped topiary. Its naturally rounded form provides consistent structure, while the soft, threadlike foliage keeps repeated spheres from feeling overly formal or visually heavy.
