Chamaecyparis pisifera 'White Pygmy' is a very dwarf, dense, bun form of Sawara cypress with loose fountain-like thread-leaf pale-green foliage that flushes nearly white in spring. In order to keep it looking its best, plant it in partial shade with adequate irrigation. After 10 years of growth, a mature specimen will measure only 12 inches (30 cm) tall and 18 inches (45 cm) wide, an annual growth rate of around 1 inch (2.5 cm).
This cultivar originated in Japan and was introduced to Europe in 1967 by nurseryman, R. S. Corley of Frensham, Surrey, United Kingdom.
