Aristolochia macrophylla, commonly known as the Dutchman's pipe, is a perennial vine native to the eastern United States. It features large, heart-shaped leaves that can grow up to 12 inches long. The plant is known for its unique, pipe-shaped flowers that bloom in late spring to early summer, attracting various pollinators. This species thrives in moist, well-drained soils and prefers partial to full shade. While it is often used in gardens for its ornamental value, caution is advised as some members of the Aristolochia genus contain toxic compounds that can be harmful if ingested.
