Asclepias verticillata (Whorled Milkweed) Unity Grown

Asclepias verticillata, commonly referred to as whorled milkweed, is an upright, native perennial wildflower that is widely known as one of the many vital host plants of monarch butterfly caterpillars (Danaus plexippus), differentiated from other milkweeds by the whorled arrangement of its leaves around its singular main stem. Growing to 12-30" tall, Asclepias verticillata is easy to grow and thrives in average to dry well-drained soil in areas with partial to full sun. With a wide tolerance of poor soil compositions, whorled milkweed can be added to a variety of garden types, where its showy white flowers add interest to the landscape throughout the summer months.

Asclepias verticillata's flowers attract butterflies and other beneficial pollinators, though flowers may be too delicate to support hummingbirds. Though whorled milkweed produces smaller compound clusters of small white flowers than other milkweeds, its compact size and shape adds an element of delicacy to pollinator gardens. Like other milkweeds, this plant produces a toxic, milky sap from damaged tissue that makes it distasteful to rabbits and deer, but care should be taken when choosing a planting site to avoid accidental ingestion by pets.
