This native tree is up to 70' tall, usually forming a single trunk up to 2' wide and a rounded to slightly elongated crown. The rough bark of the trunk is brownish gray, shallowly furrowed, and somewhat scaly. Large branches are ascending, while smaller branches are widely spreading or slightly drooping. The gray bark of the branches is smooth to slightly rough. Young twigs are smooth and brown, while new shoots are green and glabrous. Alternate leaves occur along the twigs and new shoots. These leaves are up to 5" long and ¾" across (rarely larger); they are narrowly lanceolate to ovate and finely serrated along their margins. The upper surfaces of mature leaves are medium green and glabrous, while their lower surfaces are pale whitish green, glabrous, and often slightly glaucous. Additionally, the lower leaf surfaces are flat, lacking raised veins. The slender petioles of mature leaves are about ½" long, light green to nearly red, and hairless. Young leaves are often reddish and less often pubescent, but these characteristics disappear with age. At the base of the petioles, stipules are absent, or insignificant and early-deciduous. Peach-Leaved Willow is dioecious, forming male and female catkins (aments) on separate trees. Both male and female catkins develop from short lateral branches; both types of catkins are erect to widely spreading. Male catkins are 1-2" long and cylindrical in shape, consisting of many male florets. Female catkins are 2-4" long and narrowly cylindrical in shape, consisting of ascending to widely spreading female florets. Each male floret consists of 3-5 stamens; it is short-hairy toward the base of its stamens. Each female floret consists of a narrowly pear-shaped ovary (roughly lanceoloid); it is 3-4 mm. long, green and glabrous. At the base of each female floret, there is a slender pedicel about 1.5–2.5 mm. long. The blooming period occurs from mid- to late spring and lasts about 2 weeks. The male florets wither away, while the ovaries of the female florets develop into seed capsules. At maturity, these capsules turn brown and split open, releasing tiny seeds with tufts of hair that are distributed by the wind. The root system is shallow, woody, and branching. This tree reproduces by reseeding itself.
