Chamaecyparis obtusa 'Suiroya' / Suiroya hiba Hinoki cypress

Chamaecyparis obtusa 'Suiroya' is a shrubby, medium-sized selection of Hinoki cypress with loose branching, and twisted, partially filamentous, dark green foliage, with lighter-green highlights. It is superficially similar to C. obtusa 'Coralliformis'. After 10 years of growth, a mature specimen will measure 3 to 4.5 feet (1 - 1.5 m) tall, an annual growth rate of 3 to 5 inches (7.5 - 12.5 cm).

This cultivar originated long ago in Japan. In 1971 R.S. Corley, United Kingdom, received Europe's first specimens from Dr. Tsuneshige Rokujo of Japan. Commonly seen misspellings / AKAs include 'Suiroyahiba' and 'Suirova hiba'. It should be noted that the use of the word hiba as a suffix for Hinoki cypress cultivars is considered redundant.
