Meyenia hawtayneana, commonly known as Blue Trumpet Vine, is a perennial liana native to tropical forests and woodland edges in South and Southeast Asia, including India, Bangladesh, Myanmar, and Vietnam. This species often climbs trees and shrubs to reach sunlight. It can grow to a considerable length, with stems that are woody at the base and herbaceous above. The Blue Trumpet Vine is known for its striking blue flowers, which bloom in clusters throughout the warm season, attracting pollinators such as bees and butterflies.

The Blue Trumpet Vine is valued for its ornamental flowers and its ability to cover trellises and fences quickly, providing a lush, tropical feel to gardens. It is used in cultivation primarily for vertical interest in landscapes and as a natural screen. In terms of care, it requires a well-draining soil, regular watering, and thrives in full sun to partial shade conditions. While it is not known for severe pest or disease problems, it can become invasive if not managed properly, and its vigorous growth may require regular pruning to keep it in check. It is not commonly found in cultivation outside its native range, but where it is grown, gardeners should be aware of its potential to spread.CC BY-SA 4.0
