Showy Milkweed (Asclepias speciosa)
Photo/Copy by Larry Halverson
This pretty milkweed (pictured above) is not listed in B.C. but is considered invasive. Unlike other milkweeds it can found in wetlands. This one was photographed blooming on August 9 by the wetlands near Athalmer.
Showy milkweed is toxic. It possesses moderate concentrations of cardenolides, and can poison or even kill grazing animals. However this weed has saved the lives of many Monarch Butterflies. Monarchs feed on the milkweed and toxins they ingest give the butterfly its defense. Most predators have learned that the monarch butterfly makes a poisonous snack. So the plant is also called the Butterfly weed.
