Family: Apocynaceae

Beaumontia grandiflora, commonly known as Easter Lily Vine, is a spectacular flowering climber native to the Himalayan regions of Nepal and India. It is prized in tropical and subtropical gardens worldwide for its large, fragrant, white trumpet-shaped blooms and its vigorous growth, often used to adorn walls and trellises. While it is a robust and fast-growing ornamental vine, it is important for gardeners to understand its characteristics.

Overall, the Easter Lily Vine is considered a low-risk species for invasion. It shows no history of becoming invasive or weedy in the places where it has been cultivated. Its potential to spread is limited because it produces large seeds that are not prolifically dispersed, and it cannot reproduce vegetatively from fragments. Furthermore, it is not known to be toxic, weedy, or harmful to natural ecosystems. For these reasons, it presents a minimal threat in regions like Hawaiʻi, though, as with any non-native plant, it should be monitored responsibly.
