Chamaecyparis obtusa 'Wells Special' is a robust, narrowly upright, naturally multi-stemmed, tree-form of Hinoki cypress with dense branching that grows with a slight arch, and attractive deep, emerald-green foliage. It is superficially similar to
C. obtusa 'Nana Gracilis'. It is reported to retain good color in winter in colder climates where other Cupressaceae revert to bronze. After 10 years of growth, a mature specimen will measure 10 to 15 feet (3 - 5 m) tall and half as wide, an annual growth rate of 1 to 1.5 feet (30 - 45 cm).
This cultivar originated as a seedling selected in the late 1970s by
Wells Nursery LLC, Mt. Vernon, Washington. Many consider this to be one of the nicer of the larger-growing Hinoki cypress cultivars.
