Growing to between 12" and 30" tall, Asclepias verticillata is easy to grow and thrives in average to dry well-drained soil in areas with part to full sun. With a wide tolerance of poor soil compositions, Asclepias verticillata can be added to a variety of garden types, where its showy white flowers add interest to the landscape from late spring well into the summer months.
Whorled milkweed's flowers not only attract monarch butterflies, but also hummingbirds and other beneficial pollinators.
