Cryptomeria is a monotypic genus (only one species) of conifer, native to Japan. Despite many reports that it hails from China, DNA has shown that these were brought from Japan and planted over 1000 years ago.
For over 40 years, we have been fascinated with the genus and have worked to collect as many cultivars as possible, currently 49 different ones in the garden. One of our long-time favorites is Cryptomeria japonica ‘Mitama’, an old Japanese dwarf selection that’s sold under the name ‘Globosa Nana’. Without any clipping, these retain a slightly informal green meatball shape, maturing at 6′ tall x 10′ wide. Below is our garden plant this week. Hardiness zone 5a to 9b.
