Cryptomeria japonica (Japanese Cedar)
Native: China, Japan
Location: This is an important forestry tree in Japan where it yields valuable timber. Cultivated as an ornamental in Europe and N. America.
Pollen and Seed Cones
Male and female cones are separate, but on the same tree. Male catkins are present throughout winter, then turn yellow, then shed pollen in late February or early March. Females are the tiny green rosettes at tips of shoots. They develop into mature cones.
Mature cones are green and 15mm across by autumn. These dry out, turn brown, and release their seed the following autumn.
