Frosty white buds open to form a dome of fragrant, clove-scented, pale pink stars in summer through fall. Its seed pods are entertaining, too — 4" long, upright, fuzzy, pointed pods filled with cottony seeds. Remove them before they open if you don't want a lot of babies (Asclepias speciosa, that is). All in all, this is a surprisingly ornamental Willamette Valley native! 3' x 3', and can spread via underground rhizomes as well as seeds...be sure to give this plant room to romp!
Monarch Butterflies use this as a nectar source AND host plant for their larvae! Many other pollinators use this plant as a nectar source, too: honeybees, moths, hummingbirds, and lots of other butterflies. This is a pollinator-friendly plant par excellence!
