Asclepias latifolia is a species of milkweed, also known by the common name broadleaf milkweed.[1]

It's native range includes the American southwest ranging from California and southeastern Utah to Texas and Nebraska. It grows in disturbed areas, pinyon–juniper woodlands, mixed desert scrub and hanging rock gardens.[1][2] It can be found growing in Arches National Park.[2]

It is a perennial herb that grows up to 3 ft (0.91 m) tall. Leaves have attach directly to the stem, are 3–4 in (76–102 mm) long, and are relatively broad (the specific name latifolia means "broad-leaf"). Leaves have prominent veins and pubescence that lessens with age. It grows clusters of white to pale-green flowers 0.5–0.75 in (13–19 mm) long, which bloom April to July.[1][3]

Asclepias latifolia is poisonous to some livestock. It exudes a milky latex.[2]
