Abele White Poplar Silver-leaf Poplar

=Range.=--Widely distributed in the Old World, extending in Europe from

southern Sweden to the Mediterranean, throughout northern Africa, and

eastward in Asia to the northwestern Himalayas. Introduced from England

by the early settlers and soon established in the colonial towns, as in

Plymouth and Duxbury, on the western shore of Massachusetts bay. Planted

or spontaneous over a wide area.

New Brunswick and Nova Scotia,--occasional.

New England,--occasional throughout, local, sometimes common.

Southward to Virginia.

=Habit.=--A handsome tree, resembling P. grandidentata more than any

other American poplar, but of far nobler proportions; 40-75 feet high

and 2-4 feet in diameter at the ground; growing much larger in England;

head large, spreading; round-topped, in spring enveloped in a dazzling

cloud of cotton white, which resolves itself later into two

conspicuously contrasting surfaces of dark green and silvery white.

=Bark.=--Light gray, smooth upon young trees, in old trees furrowed upon

the trunk.

=Winter Buds and Leaves.=--Buds not viscid, cottony. Leaves 1-4 inches

long, densely white-tomentose while expanding, when mature dark green

above and white-tomentose to glabrous beneath; outline ovate or deltoid,

3-5-lobed and toothed or simply toothed, teeth irregular; base

heart-shaped or truncate; apex acute to obtuse; leafstalk long, slender,

compressed; stipules soon falling.

=Inflorescence and Fruit.=--April to May. Sterile catkins 2-4 inches

long, cylindrical, fertile at first shorter,--stamens 6-16; anthers

purple: capsules 1/4 inch long, narrow-ovoid; seeds hairy.

=Horticultural Value.=--Hardy. Thrives even in very poor soils and in

exposed situations; grows rapidly in good soils; of distinctive value in

landscape gardening but not adapted for planting along streets and upon

lawns of limited area on account of its habit of throwing out numerous

suckers and its liability to damage from heavy winds. The sides of

country roads where the abele has been planted are sometimes obstructed

for a considerable distance by the thrifty shoots from underground.

=Salix discolor. Muhl.=
