Blue Rock® is the patented trade name for this cultivar. Chamaecyparis thyoides 'Versent' is a 'refreshingly Blue and spherical conifer'™, which will obtain a purple glow during the winter. The plant will retain juvenile foliage, not developing the scale-like leaves of the type. Typical rate of growth in most areas is less than 2 inches (4 - 5 cm) per year, resulting in an interesting Blue ball of foliage, 16 to 20 inches (40 - 50 cm) tall and 12 to 16 inches (30 - 40 cm) wide after 10 years in the garden. Schrauwen-Moerings nursery in Sprundel, The Netherlands is credited with the origin and introduction of this interesting new conifer in 2012. Versent's ortet was a branch mutation found on a specimen of C. thyoides 'Top Point' at the nursery. It was a Gold Medal winner at Dutch trade fair, Groot Groen in Zundert in 2012. As of 2014, Iseli Nursery of Boring, Oregon began its U.S. introduction.
