February Shrub of the Month-Bowling Ball Arborvitae
Plants can be beautiful. Plants can be ugly. Plants can be everything in between.
Thuja occidentalis ‘Bobozam’ MR. BOWLING BALL, aka Bowling Ball arborvitae, is one shrub that, to some people, goes from super cute in summer to downright ugly in winter.


At first, I wasn’t a fan of this shrub, but it’s growing on me. (pun totally intended) I’m considering them in containers for a high-end, unfussy look.
For those Plant-Geeks that want a substitution for boxwood or yew to hide your foundation or other unsightlies, bowling balls arborvitae can be a unique, low-maintenance choice. The perfectly round habit maintains itself without shearing or pruning like some other evergreens. Maturing 2-3′ high and wide, it won’t end up towering over your garage or blocking your walkway like other high-maintenance evergreens if left unpruned.

Leaf blight and canker can be a problem. Leaf miners, bagworms, mealybugs, scales, and spider mites are also possible. If you usually watch your garden closely, these can be dealt with early if they happen.
Winter burn (turns yellow-brown) in exposed sites and stem breakage from ice and snow are all concerns in winter. Full sun and well-drained soil are a MUST.

What I like about this plant;
-Face it, it’s super cute.
-Perfect rounded shape for those ‘meatball’ lovers that like perfect, round shrubs or geometric-shaped plants.
-Unique texture year-round.
-Low-maintenance
-Diverse design opportunities for rock gardens, hedges, containers, and foundations.
What’s not so great;
-Not user-friendly. As cute as it is, do not plant, transplant, hug, or pet without gloves and long sleeves.
-Full sun and well-drained soil are a must.
-Does get a dull, bronzy winter color that some might find ugly.
