Cryptomeria japonica 'Rein's Dense Jade' is a dense, broadly pyramidal dwarf cultivar of Japanese cedar. Its foliage is rich jade-green, turning purple-bronze in sufficiently cold winters. Typical rate of growth in most areas is 9 to 12 inches (22 - 30 cm) a year resulting in a 8 to 10 foot (2.5 - 3 m) conical tree after 10 years in the landscape.
John Vermeulen & Sons nursery of Neshanic Station, New Jersey is credited with the origin and introduction of 'Rein's Dense Jade' in the mid 1970s. It was propagated from a witch's broom on a specimen of Cryptomeria japonica 'Lobbii.'
