EVERGREEN TREES AND SHRUBS. 
The Globe Arbor-Vita:. Thuja globosa. — This is a pretty 
dwarf shrub, very round and compact, and quite a favorite in the 
neighborhood of Philadelphia; three to five feet high. 
The Tom Thumb Arbor-Vita;. Thuja minima ? —A roundish 
or oblate dwarf, of compact habit, which originated in the nurseries 
of Ellwanger & Barry, Rochester, N. Y., and is highly recom¬ 
mended by them. Height three to four feet. 
The Nootka Sound Arbor-Vital. Thuja plicata .—This is a 
native of the Pacific slope, and differs from the indigenous arbor- 
vitae of the eastern States in the more vertical and flatter arrange¬ 
ment of its foliage plaits, and its shorter and stouter young wood. 
Very like the Siberian in the color of its leaves, but less rich in 
the massing of its foliage: quite hardy. 
The Gigantic Arbor-Vital. Thuja gigantea .— A tree of the 
largest size, growing on the banks of the Columbia river, where it 
grows upwards of one hundred feet in height. It is said to de¬ 
velop into “ a fine, umbrella-shaped top, and picturesque head.” 
This form is unusual among evergreens, and so desirable, that, if it 
proves a characteristic of the tree, it must become popular for 
that reason alone. Hoopes, however, believes that it will not prove 
hardy, though it has not been tested long enough to determine this 
point fully. 
The Chinese Arbor-Vita;. Biota orientalis. — This is a little 
beauty when quite young, and marked by a warmer-toned green, 
and a finer quality of foliage, than the common American. It is 
also less regular in outline, and the foliage breaks apart into masses 
rather vertically. Unfortunately it has not proved hardy, and is so 
often injured by winter and summer, that instead of growing more 
beautiful as it approaches maturity, it becomes less comely, and 
after a half dozen years trial is generally pronounced scrawny. 
There is a tree in the Bartram garden south of Philadelphia, 
growing in a good exposure, which is twenty feet high, nearly as 
broad, and with a trunk ten inches in diameter; but it is decidedly 
a meagre-foliaged tree.
