Japanese False-cypress

Chamaecyparis pisifera (ka-may-sy-PAR-is pi-SIF-er-ah su-KU-moh)

Family: Cupressaceae Unknown Herbaceous (1-3 ft)

'Tsukumo' Japanese false-cypress was released in 1967 and is a slow-growing, dwarf, needled evergreen shrub in the cypress family (Cupressaceae) that can take up to 20 years to reach a height of 10 inches. Eventually it can grow up to 18 inches tall and wide. The genus name derives from the Greek words chamai , for dwarf or low to the ground, and kyparissos , for "cypress." The species epithet, pisifera, is Latin meaning “pea-bearing” and refers to the small rounded cones borne by this tree. The origin of the cultivar is not known with certainty, but it most likely originated in Japan well before the mid-20th century. In the garden, the plant grows in full sun but will do best in partial shade and in moist, well-drained, fertile soils. This is a hardy, resilient plant, but it is likely to need some shelter from strong winds. The plant’s form is rounded and flat topped like a bun with a width equal to, or greater than, its height. Because it is a conifer, it does not flower, but the blue tinted, fine textured needles provide a winter interest. Its slow rate of growth of about 1 inch per year and dwarf habit make it a popular subject of bonsai. The overlapping sprays of dense, dark-green adult foliage can make this attractive plant resemble a moss-covered rock. This plant is sometimes listed under the cultivar names, 'Pygmy' or 'Pygmaea Tsukomo'. Use ‘Tsukumo’ as a border, low hedge or specimen in a container, patio or other small space. It also works well as a companion in an Asian, rock or winter garden. Diseases, Insect Pests, and Other Plant Problems: susceptible to juniper blight, root rot and certain insect pests such as bagworms.
