Linn County Nursery 
Evergreens and adapts itself to a great 
variety of soils. It is one of the best 
for shelter, and the best large growing 
Evergreen to plant near buildings or 
along streets to be trimmed up for 
shade; few trees unite so many ele- 
ments of beauty and utility as our na- 
tive White Pine. 
Bull Pine or Western Yellow Pine (Pinus 
ponderosa) — A heavy wooded pine and a 
rapid grower, forming a tree of great 
size. Its very long coarse foliage is a 
beautiful light green and stands out 
squarely from the limbs, thus making 
it very valuable for landscape or wind- 
breaks. This tree requires the best of 
care in transplanting, but when once 
started, thrives in almost any location, 
either wet or very dry. Uudoubtedly 
this is the best pine for Western Iowa 
and beyond. 
Scotch Pine (Pinus sylvestris) — A rapid 
growing, hardy variety with stout erect 
shoots and green fol'age. Good for 
shelter or landscape planting. It is one 
of the hardiest Evergreens and adapts 
itself rapidly to the trying climate of 
the North and Northwest. It also thrives 
in the Southwest or West. It is rather 
short lived and cannot be depended upon 
for more than twenty-five or thirty 
years. 
Mugho or Dwarf Mountain Pine (Pinus 
Mugho) — This unique Alpine species 
forms a very compact, dark green, dome- 
shaped bush, broader than high. It is 
very valuable for planting on lawns, ter- 
race banks, hillsides, rockeries, etc. 
Red Pine or Norway Pine (Pinus resin- 
osa) — One of the finest of the Pines 
but not generally known. It grows al- 
most as rapidly as the White Pine and 
makes a very pretty tree. The leaves 
are very numerous, about six inches 
long and a bright dark green. 
Spruces 
American White Spruce (Picea alba) — 
A pryamidal tree of dense growth, with 
light silvery green foliage. A longer 
lived, more compact, and in all respects 
a better tree than Norway Spruce. One 
of the best for general use and very fine 
for lawn planting. mv..*« 
Black Hills Spruce — A strain of the W hite 
Spruce native to the Black Hills. Slower 
growing, more dense and better colored 
than White Spruce. Some specimens 
rival Colorado Blue Spruce in color. 
One of the hardiest and easiest to 
transplant of all the Spruces. 
Colorado Blue Spruce or Silver 
Spruce (Picea pungens) — This Ever- 
green grows over a greater range 
of territory than any other mem- 
ber of the Evergreen family. Its 
home is in the clefts and recesses 
of the Rocky Mountains, where it 
grows on barren soils, exposed to 
the roughest weather. It heads 
the family of Spruces for hard- 
iness and longe/ity and is the 
most ornamental of the Evergreen 
family. Seedlings vary from dark 
green to silvery blue; no descrip- 
tion can do it Justice, it has to be 
seen to be appreciated. 
KoHter'a Grafted Blue Sprue*- — these 
are uniform in color and finest 
blue green it is possible to obtain. 
Norway Spruce (Abies excelsa) — A 
very popular variety from Europe. 
It has been more extensively 
planted in this country than any 
other Evergreen. It is a rapid 
growre. easy to transplant, and 
adapted to a great variety of soils, 
but rather short lived. 
Arborvitaes 
American Arborvitaes (Thuya oc- 
cidentalis) — One of the finest 
Evergreens for ornamental screens 
or hedges. It grows rapidly, soon 
forming the most beautiful hedge. 
It bears trimming to any extent 
desired, and plants which have 
been rendered compact by clipping 
retain the fresh green of their 
leaves in winter better than those 
with more open foliage. For an 
ornamental hedge, plants may be 
set 15 to 24 inches apart; for a screen 
to grow tall, plant about 2 to 3 feet 
apart. 
Siberian " Arborvitae — One of the hardies*. 
and most compact growing Evergreens. 
It grows conical in shape and is very 
fine for specimens, groups or shearing. 
Foliage is deep( rich green. 
Georgre Peabody Arborvitae — One of 
the most beautiful members of the 
COLORADO BLUE SPRUCE.
