Sawara False Cypress
Evergreen, Shrubs, Trees
Intensive selection has brought these Japanese and American timber trees down in scale, so most varieties fit well into suburban gardens (some even work as container plants). Dense, richly textured foliage makes them easy to mistake for arborvitae (Thuja), but arborvitae’s leaves are entirely green, while false cypresses have white lines on the leaf undersides. Most have two distinct types of foliage: juvenile and mature. Juvenile leaves are short, needlelike, soft but often prickly; they appear on young plants and some new growth of larger trees. Mature foliage consists of tiny, scalelike, overlapping leaves. Cones are small and round.
New varieties appear each year—hundreds are on the market at any moment—and mislabeling is common, since many of these plants closely resemble one another. Numerous dwarf and variegated kinds are well suited for bonsai and rock gardens.
All except C. thyoides are native to the Pacific Rim, so they prosper in humid environments. Pinch out or cut back tips of new growth to control size and shape; don’t cut back into old, leafless wood. All types, including trees, can be sheared into hedges. All need good drainage and protection from wind.
