Milkweed

Asclepias spp.
In the United States: Native · also called butterfly flower, silkweed, silky swallow-wort, Virginia silkweed

Honeybees are highly attracted to common milkweed for its abundant nectar, often prioritizing it over other blooms during the midsummer peak flowering period. Although pollen is present in specialized pollinia sacs, honeybees typically visit without effectively collecting it, discarding the pollinia instead. The plant propagates aggressively through underground rhizomes, necessitating barriers or careful site selection to prevent unwanted spread in managed landscapes.
