Cultural Significance
Known as "Chain of Love" and "Queen's Wreath," Antigonon leptopus has been cultivated since the early 20th century for its spectacular cascades of heart-shaped pink flowers. In Mexico and Central America, where it is native, the plant is valued for both ornament and food - the flowers, leaves, seeds, and tubers are all edible. However, its introduction to tropical islands and warm regions worldwide has made it one of the most aggressive invasive plants, capable of smothering native vegetation. The name "Coral Vine" refers to the coral-pink color of its abundant blooms.Shop Our Floral Collection
