Cunninghamia lanceolata 'Glauca' / blue China fir

Cunninghamia lanceolata 'Glauca' is a large, tree-form of China fir which was selected for its pleasant powder-blue foliage and better winter hardiness than the typical species. Its growth habit is similar to the species, only somewhat more compact and bushy. Depending on the nature of the cuttings taken for propagation, a young tree may take many years to develop a strong central leader. Typical rate of growth in most areas is 4 to 16 inches (10 - 40 cm) per year, resulting in a tree or broad shrub 3 to 12 feet (1 - 4 m) after 10 years in the landscape.

Many conifer gardeners purposely cut the entire plant to the ground on a periodic basis to encourage the lush bushy form of younger plants. This practice of coppicing is a good option in areas where winter hardiness or other growing conditions are marginal for good tree growth.

This is a very old cultivar that has been in the nursery trade since the 1850s. It should also be noted that more than one clone is in circulation, so assertions as to hardiness must be viewed with skepticism.

Do you have Cunninghamia lanceolata glauca for sale?

David Olszyk

Dan, with the exception of the small handful of plants we sell each year for our Collectors' Conifer of the Year program, the ACS doesn't sell plants. The mission of the ACS is education and conservancy. We have no retail presence.

However, if you join the Society and attend our conferences, there's the possibility that this plant could show up on an auction table sometime, somewhere; but honestly, it'd be quicker to work with your local garden center.
