![]() ![]() Altthough these trees are promising, they are not 100% resistant to butternut canker.Įxcellent clone material suitable for riparian, environmental restoration, and wildlife planting here in the Midwest. Our butternut are from the USDA Forest Service’s grafted pure seed orchards. Pence “Select” seedlings from the best 200 trees of 44,000 planted on 120 acres in 1989. Native seed sources from Ohio, Indiana, and Illinois It is also one of the more common softwoods used in export markets.Scotch Pine (Christmas tree seed sources from Europe as follows) It is used widely in construction, laminated timbers, plywood and high grade veneer, interior trim, cabinet work, pallets, boxes, ladders and flooring. It is straight grained and moderately hard. The sapwood is white to pale yellow while the heartwood is orange-red with high contrast between earlywood and latewood. Plantation trees are normally sheared and will produce a crop within 7 to over 10 years depending upon the site and growing area.ĭouglas-fir is one of the stronger of the softwoods and is widely used for structural purposes. It is shipped to the majority of the states and is also exported to the Hawaiian Islands, Guam and some Asian markets. Nationally, it remains one of the most popular Christmas trees species. It is preferred because of its ability to withstand the more harsh growing conditions than the Pacific Northwest seed sources. glauca) has been extensively planted throughout several midwestern state Christmas tree plantations. Today, few trees come from forest lands.Īn interior strain from the Rocky Mountains (P. Since the 1950’s, the transformation from growing trees in the wild to culturing them on plantations has been dramatic. During the following 40 years, nearly all trees were harvested from forest lands. The Douglas-fir has been the major Christmas tree species used in the Pacific Northwest since the 1920’s. The practicality of these techniques has yet to be proven and remains more of a curiosity rather than a new trend to produce seedlings from trees that exhibit superior Christmas tree characteristics. Research has been done on grafting and rooting from cuttings. It is usually sold as a two or three year old transplant. Seed is generally germinated in bare root nurseries and increasingly in container nurseries. Thus many ancient old-growth forests contain large Douglas-fir that represent the legacy of fires that occurred many centuries ago. ![]() The trees can live for a thousand years, largely due to a very thick bark that allows them to survive moderate fires. Under natural conditions, Douglas-fir has established primarily after fires on wetter sites. macrocarpa), the other Pseudotsuga species in western North America, has a very restricted range limited to Southern California and Baja, Mexico. On the coasts, it is associated with western hemlock and other conifers.īigcone Douglas-fir (P. On the west side of the Cascades and Sierra Nevada, it is often the predominate species, but usually occurs in conjunction with several other confers. It grows under a wide variety of environments from extremely dry, low elevation sites to moist sites. The entire range includes central California, western Oregon and Washington, parts of the Rockies and extends north to Alaska. The cones open in the late summer to disperse the seeds and will continue to hang on the trees through the fall. They are reddish-brown to gray, 3″ long and do not dissipate to spread seed as do true firs (Abies sp.). Young cones are small, oval shaped and hang downward. Pollen strobili are small and reddish-brown. They have a sweet fragrance when crushed. ![]() The needles are dark green or blue green, 1 to 1 1/2 inches long, soft to the touch and radiate out in all directions from the branch. The branches are spreading to drooping, the buds sharply pointed and the bark is very thick, fluted, ridged, rough and dark brown. ![]() This wide ranging species grows from 70 to 250 feet tall. Pseudotsuga menziesii (Mirb.) Franco Descriptionĭouglas-fir is not related to the true firs. ![]()
