Salix amygdaloides (Peachleaf Willow) is a species of willow native to southern Canada and the United States, from Quebec west to eastern British Columbia, southeast to western Kentucky, and southwest to Arizona and Nevada.
It is a small to medium-sized deciduous tree, growing to 4–20 m tall; besides the cottonwoods it is the largest tree native on the prairies. It has a single trunk, or sometimes several shorter trunks. The leaves are lanceolate, 3-13 cm long and 1-4 cm wide, yellowish green with a pale, whitish underside and a finely serrated margin. The flowers are yellow catkins, 3-8 cm long, produced in the spring with the leaves. The reddish-yellow fruit matures in late spring or early summer, the individual capsules 4-6 mm long.
It can be found on the northern prairies, often near streams, and accompanying cottonwoods. As both the common and scientific name suggests, the leaves bear some similarity to those of a peach or an almond (Latin, amygdalus).
