Chamaecyparis obtusa 'Chilworth' / Chilworth Hinoki cypress

Chamaecyparis obtusa 'Chilworth' is an exceptional miniature selection of Hinoki cypress with tiny, recurving feather-like brachlets of light-green foliage that assumes a bronze-ish cast in the winter in colder climates. With age, plants will attain more of a conical shape. After 10 years, a mature specimen will only measure around 4 inches (10 cm) tall and wide, an annual rate of growth of 0.5 inch (1 cm) or less.

This cultivar originated as a seedling selected around 1910 by George Gardiner, nursery foreman at W.H. Rogers & Sons' Red Lodge Nursery, Eastleigh, United Kingdom. Gardiner is renowned for introducing many exceptional miniature Hinoki cultivars. Rogers & Sons introduced it to the nursery trade in the late 1920s.
