Asclepias verticillata

Milkweed - Whorled

Whorled Milkweed is a tough native perennial which serves as a critical food source for all stages of Monarch butterfly development. The delicate white umbel shaped flowers appear from June through August, on top of the narrow leaves. The common name ‘Whorled’ refers to the way the leaves circle the stems. Because of Asclepias verticillata’s white sap, Whorled Milkweed is not eaten by deer or rodents. The silky seeds are released in fall from the pods (also useful in dried flower arrangements).
