Thuja occidentalis 'Wareana' is a dense, pyramidal selection of arborvitae with stout ascending branches and thick, short, mostly vertically arranged compressed branchlets of coarse, dark-green foliage that does not tend to bronze in winter. After 10 years of growth, a mature specimen will measure 8 to 10 feet (2.5 - 3 m) tall and 6 to 8 feet (1.75 - 2.5 m) wide, an annual growth rate of 1 foot (30 cm) or less.
This cultivar originated as a seedling selected in the late 1820s by G. Ware, The Nurseryman of Coventry, United Kingdom. It is possibly named his father James Ware, the mayor of Coventry.
Ken Church: This plant is definitely fully hardy in zone 3 and probably in zone 2. I live in zone 3 and have a row of 26 of these placed on top of a 6-foot high berm as a wind break. They never winter-burn, although I did lose a couple early on until I put down wood chips to hold moisture near the roots for the winter.
