ROADWEEDS OF THE UPPER PENINSULA
|Milkweeds (Asclepias syriaca and A. incarnata)|
Milkweeds have pretty cool flowers if you take a close look at them. The flowers aren't "normal" with a pair of whorls pointed in opposite directions from each other. The light, silky seeds are released from split, dried pods in late summer, a familiar sight to many. All but one species have milky, sticky sap and are oppositely-branched. There are about a dozen species in Michigan. All are native. Two are on the Michigan "threatened" species list and one is on the Michigan "endangered" species list. The common milkweed (A. syriaca) is host to monarch butterflies. It's what you usually see when you spot milkweeds. Swamp milkweed (A. incarnata) has the prettiest flowers, a much deeper purple.
