bed, red.

=Fruit.=--June. Capsules, in elongated catkins, conical; seeds numerous,
white-hairy.

=Horticultural Value.=--Hardy throughout New England in the most exposed
situations; grows almost anywhere, but prefers a moist, rich loam; grows
rapidly; foliage and spray thin; generally short-lived; often used as a
screen for slow-growing trees; type seldom found in nurseries, but one
or two horticultural forms are occasionally offered. Propagated from
seed or cuttings.
