King's Mantle (*Thunbergia erecta), also called Bush Clock Vine, is a fast-growing, tropical evergreen shrub from Africa known for its vibrant, trumpet-shaped purple flowers with yellow throats, making it a popular, low-maintenance choice for hedges or accent plants in warm climates (USDA Zones 9-11). It thrives in full sun to partial shade with well-draining soil and consistent moisture, offering year-round blooms in mild winters, attracting butterflies, and tolerating pruning well to control its 4-8 foot size.
