About
Cryptomeria japonica 'Spiralis' is a slow-growing, semi-dwarf evergreen conifer characterized by its narrow, wedge-shaped needles that curve and twist spirally around the branches. In its early stages, the plant presents a jagged silhouette, gradually maturing into a broad dome shape and eventually forming a tall conical structure that can reach heights of up to 6 meters.
