Asclepias tuberosa, commonly known as Butterfly Milkweed, is a native perennial wildflower found throughout much of the United States. This upright, clump-forming milkweed is known for its vivid orange flower clusters that bloom from early to mid-summer. Typically growing 1 to 3 feet tall, Butterfly Milkweed thrives in full sun and dry to moderately moist, well-drained soils. Unlike many other milkweeds, it prefers lean, sandy, or rocky sites and does not tolerate wet conditions. It is a critical host plant for Monarch butterfly caterpillars and a highly attractive nectar source for bees and butterflies.
