Th e balsam poplar, in th e climate o f London, is th e very first tre e th a t comes
into leaf j its foliage is o f a rich gamboge yellow, and so fragrant as in moist
evenings to perfume th e surrounding air. The tre e is remarkably hardy, but,
unless in the vicinity o f water, it seldom attains a large size in England, o r is
of great duration. Readily propagated by suckers, which it sends up in abundance
; or by cuttings, which, however, do not strike so readily as those of th e
poplars belonging to P . nigra.

The Ontario poplar bears a close general
resemblance to th e balsam poplar : it has th e i
rigid fastigiate habit o f th a t tree, its fine
fragrance, and its property o f throwing up
numerous suckers ; b u t it differs from it, in
having very large heart-shaped leaves, and in (
attaining a larger size, b oth in its native
country, and in British gardens. T h e buds
are covered with th e same balsamic substance
as those o f P . baisamifera ; and th e
leaves are o f th e same fine yellow colour in
spring, though they corné o u t a fortnight
later. Like those o f th e balsam poplar, they
preserve, a t all stages o f the ir growtii, the
same shape. Readily propagated by cuttings
or suckers, but th e tre e will n o t attain a

though, as th e roots creep along th e surface, th e soil need not be deep.
