Chamaecyparis obtusa 'Tonia' / Tonia Hinoki cypress

Chamaecyparis obtusa 'Tonia' is a slow-growing pyramidal selection of Hinoki cypress with dense branching and subtle off-white variegation randomly scattered throughout the plant. It can be best described as a lightly variegated C. obtusa 'Nana Gracilis'. After 10 years of growth, a mature specimen will measure 16 to 20 inches (40 - 50 cm) tall and wide, an annual growth rate of 1.5 to 2 inches (3 - 5 cm).

This cultivar originated as a seedling selected in the late 1920s by William Hage Nursery, Boskoop, The Netherlands. It is commonly seen listed under the name 'Nana Tonia'.
