Asclepias tuberosa is a species of milkweed native to eastern North America.

It is a perennial plant growing to 0.3–1 metre (10 in–3 ft 3 in) tall, with clustered orange or yellow flowers from early summer to early fall. The leaves are spirally arranged, lanceolate, 5–12 cm long, and 2–3 cm broad.
This plant favors dry, sand or gravel soil, but has also been reported on stream margins. It requires full sun.
It is commonly known as Butterfly Weed because of the butterflies that are attracted to the plant by its color and its copious production of nectar. It is also the larval food plant of the Queen and Monarch butterflies. Hummingbirds, bees and other insects are also attracted.[2]
Extracts were used by Native Americans as an expectorant for wet coughs and other pulmonary ailments.[citation needed] Use of the herb is contraindicated in pregnancy, during lactation or with infants due to the small amount of cardiac glycosides.[3]
The plant looks similar to the Lanceolate Milkweed (Asclepias lanceolata), but is uniquely identified by the larger number of flowers, and the hairy stems that are not milky when broken. It is most commonly found in fields with dry soil.

Seen at a park overlooking the Niagara Falls in the last week of June, 17.

yes . milkweed called butterfly milkweed but then most milkweeds are preferred by butterflies. but this one seems to too well tended. we might assume there are chemicals sprayed on or around it, so not so life giving to the poor monarch

It was a cultivated plant at the entrance of the park.
