Fun Facts
Hemp Dogbane is a tall, upright native perennial that grows in moist meadows, along stream banks, and in open areas. In summer, it produces clusters of small pinkish-white flowers that attract pollinators, while its fibrous stems have been historically used to make rope and cordage.
Hemp Dogbane is clump-forming and slow-spreading, it is manageable in larger naturalized plantings or wildlife gardens. It adds both ecological and historical value to native landscapes, and can help stabilize slopes or moist areas where other plants may struggle.
