Alternative Evergreens
Just
a handful of species make up the majority of evergreens
planted. This lack of diversity is starting to be a real
problem in areas where diseases are decimating both Scotch pine and
Austrian pine, the two most commonly planted pine trees of the last 50
years. Fortunately, there are several less-common types of evergreens
to consider.

Concolor
Fir
(Abies
concolor): Graceful, soft,
silvery-blue foliage
makes it
a nice alternative to Colorado spruce. Grows to 70 feet tall by 40 feet
wide.
Douglas
Fir (Pseudotsuga menziesii):
Soft blue-green needles with
attractive
cones. Grows to 70 by 30.
Bosnian
Pine (Pinus heldreichii):
A graceful, dark green, more
compact tree
that is a nice substitute for Austrian pine or Scotch pine. Grows to 50
by 30.

Limber
Pine (Pinus flexilis):
Native to western Great Plains where it makes a good, drought-tolerant,
long-lived landscape tree on well-drained soils. Grows to 60 by 40.
Pinyon
Pine (Pinus cembroides):
A slow growing, extremely drought-tolerant tree. Best suited
to well-drained soils of western Nebraska where it will grow up to 25
by 15.
|
Bristlecone
Pine (Pinus aristata):
A small, slow growing, picturesque tree with bottlebrush like tufts of
needles at branch tips. Best on well-drained soils of western Nebraska.
Grows to 30 by 20.
Serbian
Spruce (Picea omorika):
Similar to Norway spruce with graceful, drooping branch tips and
attractively streaked silver-green foliage. Grows to 60 by 30. |
