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?

Maxwell Cohn

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

Evelyn Smith

One of my plants was damaged and has areas where foliage died. What is the best way to encourage it to come back into shape?

Maxwell Cohn

just give it time. The holes will fill in all by themselves within 5 to 7 years.

Sam

Can these shrubs be cut back every year to a circular 20-25" ?

Maxwell Cohn

I think you can get away with that for a few years, but the plant really wants to be much larger.

My 7 year old Cryptomeria japonica 'Globosa Nana' / globose dwarf Japanese cedar.
Has dead brown ends There was a brakish water flood. What can be done to help the plant recover. Thank you.

I am not a conifer expert in any way..but the registered nurse that I am wonders about the level of sodium your tree was exposed to during the brakish water flood. Maybe a local nursery or your county extension can assist with a diagnosis. Good luck.

Hi, is Cryptomeria japonica black walnut tolerant? I see that Juniperus Virginia for the Globosa variety per university of Minnesota website article is be tolerant but not sure if that is technically the same ? Any help would be most grateful. Thank you, Dave

I have three beautiful specimens of this plant but at 20 years old they are now bigger than the space for them. Do they regrow after being pruned back into old wood?
Thanks
