Summary

Cynanchum viminale, commonly known as Latexvine, Devil’s Twine, or Caustic Vine, is a perennial vine native to arid and semi-arid regions, including savannas, grasslands, and open woodlands of Africa, South Asia, and Australia. It typically climbs on other vegetation, reaching various lengths depending on the supporting structure. The plant features slender stems and produces small, white, and inconspicuous flowers that may go unnoticed. The vine is well adapted to survive in harsh conditions with its succulent-like leaves that conserve water.

Latexvine is known for its hardiness and ability to thrive with minimal care, making it suitable for xeriscaping and as a ground cover in arid gardens. However, its aggressive growth habit and prolific seeding require careful management in cultivation. It requires well-drained soil and can tolerate a range of light conditions from full sun to part shade. While it can survive on low water, moderate watering will support more vigorous growth. Gardeners should be cautious when handling this plant, as it exudes a milky latex that can be irritating to the skin and eyes.CC BY-SA 4.0
