We've got 3 of these and also one of the Rocky Mountain species. It'll be interesting to see the contrast between the Pacific and the RM trees when they get bigger.

These will grow in hot Summer areas like her in Kentucky if you can get them established. They need irrigation to help reduce heat stress at first and do best in loose deep soils. Best sited where they get some shade (not directly overhead) in hot afternoons but with room to grow. I've seen some nice specimens around here but usually newly planted trees will end up dying if not coddled and properly sited. The variety glauca or cultivars of it are the most attractive.

This tree will grow in zone 7 as reported. Probably not to great heights, but I pass a healthy twenty-footer everyday on the way to work (and the cones show that it definitely is a Douglas). Just shows that 100% of the trees you don't plant will not survive.

Also known as "Douglas Spruce" and "Douglastree", this conifer can reach a height of about 200 ft. in the Pacific Northwestern United States but only gets to about 100-130 ft. high in Arizona. The trunk can get up to 6 ft. thick in the Pacific Northwest. The dark reddish brown bark is very thick and has deep furrows. The red-brown and thin cones have rounded scales and hang from the branches instead of stand up on the branches. They have 3" long papery bracts that have three points on them and come out from between the scales. The flat, narrow and soft needles radiate in all directions from the branch, are blue-green and about 1.125" long. This tree occures in nature at about 6500-10,000 ft. elevation but only at 5000 ft. in canyons. It grows with other spruce-firs and Ponderosa pine trees... read more

We purchased a live Douglas Fir as a Christmas tree 5 years ago and planted it right after Christmas that year. It has doubled it's size since then and was doing wonderfully. Unfortunately, my husband did not get the fence up around it two winters ago and the deer grazed this tree up to about 4 feet. Although some of the needles are starting to come back, we may have to remove them several feet up the trunk to help "shape" the tree once more. Those who live in deer-populated areas take note and make sure you protect young trees!

These trees are very large, and very beautiful. (Then again, I'll call any massive tree beautiful) When these trees are mature they are very tall and even though the crown does become irregular, it retains its conical shape. The young trees have narrowly conical crowns with branches that extend nearly to the ground, the typical Christmas tree shape. Even a young tree can be quite tall.

The Douglas-Fir frequently grows to more than 200 feet tall, 6 to 7 feet in trunk diameter, and more than 500 years old. Many records from the 1800s and early 1900s indicate that Douglas-Fir regularly grew over 300 feet, and even approached 400 feet. However, these large specimens were logged, leaving the diminished trees of today. The largest living specimen is 328 feet tall, located in Coos ... read more
