Aristolochia ringens, commonly known as gaping Dutchman’s pipe, is a perennial vine native to tropical rainforests and secondary forests in Central and South America, including Panama, Bolivia, Colombia, and Venezuela. It is known for its distinctive flowers, which have a large, inflated calyx that resembles a curved pipe and are typically green with purple-brown markings. The flowers can be quite showy and emit a strong, unpleasant odor to attract pollinating insects. This species can climb to heights of 10-15 feet (3-4.5 meters) when supported.

Gaping Dutchman’s pipe is valued for its unique, ornamental flowers and is often used in tropical and subtropical gardens. It can be grown on trellises, arbors, or fences to add vertical interest. In cultivation, it requires moist, well-drained soil and thrives in partial shade to full sun. Regular watering is necessary, especially during dry periods. While it is not typically troubled by serious pests or diseases, it is important to monitor for common vine issues such as leaf spot or mildew. Due to its rapid growth and potential to spread, it should be planted with care and regularly maintained to prevent unwanted spread.CC BY-SA 4.0
