Cryptomeria japonica 'Pom Pom' is a dwarf selection of Japanese cedar with light green, refined foliage. 'Pom Pom'™ displays a rounded habit when young, but will eventually form a leader. An interesting and attractive feature is how the terminals will naturally cluster forming the "pom poms" that give this plant its fanciful name. Typical rate of growth 2 inches (5 cm) annually, producing a shrubby specimen, 2 feet tall and wide (60 x 60 cm) after 10 years.
Buchholz and Buchholz Nursery of Gaston, OR described this cultivar in their online catalog in 2009. Beyond that, little is known of its origin or introduction.
