DECIDUOUS ORNAMENTAL TREES.

are of a deep blue ; the young shoots of a bright green, sprink- 
led with dots of the same colour, which disappear as the sea- 
son advances. It may readily be distinguished from the 
White ash by its bark, which is of a duller hue, and less 
deeply furrowed. The Black ash is altogether a tree of less 
stature than the preceding. 
The other native sorts are the Red ash, ( F \ tomentosa ,) 
with the bark of a deep brown tint, found in Pennsylvania : 
the Green ash, (F. viridis ,) which also grows in Pennsyl- 
vania, and is remarkable for the brilliant green of both sides 
of the leaves : the Blue ash, (F. quadrangulata ,) a beau- 
tiful tree of Kentucky, 70 feet high, distinguished by the four 
opposite membranes of a greenish colour, found on the young 
shoots: and the Carolina ash, (F. platycarpa ,) a small 
tree, the leaves of which are covered with a thick down in 
spring. 
The common European ash, (F. excelsior ,) strongly resem- 
bles the White ash. It may, however, easily be known by its 
very black buds, and longer, more serrated leaflets, which 
are sessile, instead of being furnished with petioles like the 
White ash. This fine tree, as well as the White ash, grows 
to 80 or 90 feet in height, with a very handsome head. 
The Weeping ash , fig. 33, is a very remarkable variety of 
the European ash, with pendulous or weeping branches ; 
and is worthy a place in every lawn, for its curious ramifica- 
tion, as well as for its general beauty. It is generally 
propagated by grafting on any common stock as the White 
ash, 7 or 8 feet high, when the branches immediately begin 
to turn down in a very striking and peculiar manner. The 
droop of the branches is hardly a graceful one, yet it is so 
unique, either when leafless, or in full foliage, that it has long 
been one of our greatest favourites.
