Cedar Trees Overview
Thuja is a small genus of hardy, evergreen, coniferous trees and shrubs with flattened branchlets, originating from forested regions in North America and Eastern Asia. They have aromatic, scale-like leaves that are diamond-shaped or wedge-shaped, arranged in 2 ranks of oppositely arranged pairs. They produce small female or male cones. This genus is widely utilised as ornamental specimen trees (some having gold or bronze-tinted foliage) and also for hedging, with numerous cultivars produced for landscaping. Small species can be used for rock gardens. These plants are commonly known by the names Cedar Trees, Arborvitae, Thuja and Red Cedar. Thuja blight is a fungal disease that attacks the leaves and shoots, usually of the lower branches. Young trees in particular, can be badly damaged - especially if densely planted and with poor air circulation. Thuja should also be protected from cold, dry winds.
