Leaves are not typically triangular in shape, but are broadly ovate or round. This tree may be a hybrid between P. deltoides and P. balsamifera. Bark is gray and smooth. Buds are covered with a varnish-like, sticky resin and are quite pleasant to smell. The first scale of the side bud is borne on the side opposite the twig.
Twigs are fragrant.
Leaves are not lobed, but are broad and have a cordate leaf base. Foliage has a dark green color with whitish hairs beneath the leaf becoming dense along the veins. Less pubescence is present on the upper leaf surface. Petioles are not flattened but are rounded, or nearly so. Monoecious flowers open in March or April.
