Thuja occidentalis Smaragd otherwise known as the Dwarf American Arborvitae is a dense, evergreen, dwarf conifer shrub with very attractive and aromatic, bright green foliage.
It grows slowly in a dome shape at first then changes to a pyramid shape later.
It produces tiny yellow/green cones that turn brown and makes a great formal hedge when clipped.
These very architectural plants are perfect for city courtyards and on patios in tubs and they also suit rock gardens very well.
