Anna's Magic Ball arborvitae

Thuja occidentalis 'Anna van Vloten'

Golden evergreen foliage gives Thuja occidentalis 'Anna van Vloten' a distinct presence in a small planting. This dwarf arborvitae forms a dense, rounded globe, generally reaching about 10–18 inches high and 12–18 inches wide. Its color and compact outline remain visible through winter, making it useful near a path or at the front of a border where its mature width can be accommodated. This small shrub needs moisture at its roots without standing water; a sunny or partly shaded position suits it. In Southwest Washington, choose a spot that drains through wet weather and water during dry periods while the plant establishes. Deer may browse the foliage.
