Primo® Dwarf Arborvitae

Primo® Arborvitae - Dwarf Evergreen Appeal

The Primo® Dwarf Arborvitae (Thuja occidentalis 'Islprim') is a stately and stylish mini-evergreen! It features a compact, pyramidal habit and dense, rich green foliage that shines all year round. This Arborvitae cultivar is a slow grower, making it perfect for tight garden spaces or formal hedges where neatness matters and time is short on supply!

Primo® resists browning in winter—a flaw (or is it a feature?) in many other evergreens—and boasts a tight, uniform structure that makes it feel like Ma Nature herself gave it a topiary trim!

With a mature height of about 3-4 feet and a spread of up to 18 inches wide, Primo® Arborvitae maintains a narrow, upright form with soft, flattened sprays of scale-like foliage in a deep emerald green. Unlike leggier conifers, this one stays lush to the ground with no bald ankles, making it a favorite for screening, foundations, and flanking walkways. While it doesn't produce showy cones or flowers, its tidy symmetry and color offer four seasons of reliable, formal flair!
