Hinoki Cypress (Chamaecyparis obtusa)

Hinoki Cypress Plant Hinoki Cypress A variety of trees belonging to the plant family Cupressaceae are commonly called "Cypress." At the Arboretum, several plantings in the Conifer Collection and the Dwarf and Unusual Conifer Collection belong to the genus Chamaecyparis and are known as Cypress or False Cypress. The Hinoki Cypress is a native of Japan and Taiwan. It has scale-like leaves borne on spreading branches that are in flattened planes. Dwarf cultivars of this species are commonly used in landscaping. An example of one of these dwarf cultivars is Chamaecyparis obtusa 'Filicoides', which can be seen in the Dwarf and Unusual Conifer Collection.

Sawara Cypress (Chamaecyparis pisifera)

Sawara Cypress Plant Sawara Cypress Sawara Cypress, considered a sacred tree in Japan, is a valuable timber species in that country. Although the original species may grow as high as 60 ft, many of the cultivars have been selected to produce dwarf plants that are used extensively in landscaping. A good example present in the Conifer Collection is Golden Threadleaf Sawara Cypress (Chamaecyparis pisifera 'Filifera Aurea Nana'). It has drooping yellow, threadlike foliage and reddish-brown bark that peels on older trees. This cultivar is generally described as a dwarf form, but our specimen is much taller. The Cupressaceae is a large family that includes 18 genera and many familiar plants at the Arboretum such as Junipers, Cedars, and Bald Cypress.
