American arborvitae
Thuja occidentalis 'Klmeighteen' PATRIOT
American arborvitae (Thuja occidentalis 'Klmeighteen' PATRIOT) is an evergreen conifer with deep green foliage and an abundance of feathery branches creating an elegant, rounded form. Growing up to 15 feet or more in the wild, Patriot cultivar stays much smaller, achieving a maximum height of about 8 feet. Its dense foliage is sprinkled with yellow tips in the spring and makes a golden-green winter display. It requires very little maintenance and tolerates most soil types as long as it is well-drained. A perfect choice for foundation planting, hedges or even as a single specimen. Add some American ardor to your landscape with 'Klmeighteen' PATRIOT American arborvitae.
