Summary

Clematis crispa, commonly known as Swamp Leather Flower, is a deciduous perennial vine native to wetlands, swamp margins, and lowland woods in the Southeastern United States. It typically climbs to heights of 6-10 feet (1.8-3 meters) with a spread of 3-6 feet (0.9-1.8 meters). The plant features nodding, bell-shaped flowers with recurved sepals that are usually lavender to pale blue, occasionally with a pinkish hue, and bloom from late spring to early summer. The flowers are quite showy and attract pollinators such as bees and butterflies.

Swamp Leather Flower is valued for its unique, attractive flowers and its ability to thrive in moist conditions, making it a suitable choice for rain gardens, water edges, and naturalized areas. It can also be trained on trellises, arbors, or fences in garden settings. This Clematis species requires consistently moist soil and benefits from mulching to retain soil moisture. It prefers a location with full sun to part shade and soil that is rich in organic matter with good drainage. While it is relatively low maintenance, it can be susceptible to Clematis wilt, a fungal disease that causes sudden wilting and death of stems. To prevent this, ensure good air circulation and avoid overhead watering. It is also important to note that all parts of the plant are toxic if ingested, so caution should be exercised if planting in areas accessible to pets or children.CC BY-SA 4.0
