Thuja occidentalis 'Gracilis' / graceful eastern arborvitae

Thuja occidentalis 'Gracilis' is a moderately fast-growing, upright form of eastern arborvitae with loose, open branching, slender, pendant branching and light-green foliage. After 10 years of growth, a mature specimen will measure 6 feet (2 m) tall and 4 feet (1.3 m) wide, an annual growth rate of 6 to 8 inches.

This cultivar originated as a seedling selected in the 1870s by Scotts Nurseries, United Kingdom. Translated from the Latin language, gracilis means "graceful" and/or "slender".
