Asclepias oenotheroides is a middle elevation milkweed with distinctive crenate leaves. The flowers are greenish white. The flower of this species is unique among milkweeds. The long, slender hoods extend beyond the stigmatic groove and flare or bow outward at the top. This species survives periodic droughts and occasional mowing even though it has shallow roots. It leafs out and flowers if rains follow a dry period.
