Emerald green arborvitae, known botanically as Thuja, is an evergreen perennial native to Eastern North America. Arborvitae is used singly or in pairs as specimen trees and also commonly used in mass linear plantings to serve as hedging, windbreaks, living fences and screening. It responds well to pruning and shaping, bouncing back with new growth. Arborvitae does not require pruning to encourage growth but only for control of size, shape and appearance.
