When we talk about conifers for the Southeast, we have to include Cunninghamia lanceolata. This giant of the landscape holds a special place in the realm of southern gardening, as it has historic significance as a “southern heritage” tree. It is commonly found growing around old homesteads and cemeteries throughout the southern United States.
Cunninghamia lanceolata, commonly called China fir, is an evergreen conifer that is native to areas of China, Taiwan, and Vietnam where it can reach heights up to 150 feet (50 m) tall. In cultivation, it commonly grows 35 to 70 feet (10 - 20 m) tall. It tends to sucker and often grows in a multi-trunked form with sharply-pointed, (specific epithet means spear-shaped) finely-toothed foliage. The green to blue-green needles grow up to 2.75 inch (7 cm) long. Foliage may bronze in cold winters. China fir displays oval to globose fruiting cones 1.5 inches (3.75 cm) in diameter that appear in small groups of 1 to 3 at the shoot ends. The brown bark of mature trees exfoliates in strips to reveal reddish-brown inner bark. This is a prized timber tree in China, named after James Cunninghame (died ca. 1709) who was a surgeon for the East India Company in Amoy, China.
Best grown in moist, acidic, well-drained soils in part shade to full sun and hardy in USDA Zones 7 to 9, China fir will experience foliar damage in extreme winters, and its use is questionable north of Washington D.C. Branches killed by winter should be promptly pruned out. Cunninghamia lanceolata ‘Glauca’, an attractive blue form, reportedly has better winter hardiness (to -10°F / -23°C). In warm winter climates, China fir can develop into a beautiful tree. Its sheer size and uniqueness of texture make it a compliment to the landscape if given enough space to flourish.
