Cryptomeria japonica 'Mushroom' / Mushroom Japanese cedar

Cryptomeria japonica 'Mushroom' is a flat-topped, globose, dwarf selection of Japanese cedar with juvenile foliage that is light green in spring and summer, later transitioning to a dramatic russet-brown in winter. Typical rate of growth in most areas is 2 to 3 inches (5 - 7 cm) per year, resulting a mounded, mushroom-shaped specimen 20 inches (50 cm) tall and 30 inches (70 cm) or more wide after 10 years in the garden.

Although this cultivar is believed to have been of Japanese origin, this claim has yet to be verified. It is believed to have been introduced to the nursery trade by a nursery in Australia.
