Cryptomeria japonica 'Globosa Nana' / globose dwarf Japanese cedar

Cryptomeria japonica 'Globosa Nana' is a dwarf globose selection of Japanese cedar with uniform, somewhat loose branching bearing nodding tips, particularly in spring. Awl-like foliage is dense and compact, turning yellowish green in the heat of the summer and more blueish green in winter. After 10 years of growth, a mature specimen will measure 32 to 40 inches (80 - 100 cm) tall and wide, an annual growth rate of 3 to 4 inches (7.5 - 10 cm).

This is an extremely old cultivar that originated long ago in Japan. Murray Hornibrook first described and named it in his 1923 book, Dwarf and Slow-growing Conifers. It is thought to have come to Europe with the Japanese name 'Mitama' or 'Mitama-sugi' which should take precedence as a cultivar name.

Is a Dwarf Cryptomeria "Globosa Nana" and a Cryptomeria "Globosa Nana" the same thing? Is there only one size?

David Olszyk

definitely all the same thing. They come in many, many sizes depending on how old they are.
