Asclepias latifolia is the only milkweed in the Gila Wilderness with leaves that are several centimeters wide, about half as wide as they are long. The veins of the leaves are conspicuous and the leaf apices are frequently mucronate. The flowers, which tend to hide from view, are axillary and greenish white. The pedicel to the fruit (a follicle) is sharply bent (deflexed.)
