Thunbergia alata, commonly known as the black-eyed Susan vine, is a fast-growing, twining perennial climber native to eastern Africa and widely cultivated as an ornamental plant in warm and temperate regions. It features heart-shaped to triangular leaves and vibrant, five-petaled flowers that range in color from golden yellow and orange to white and cream, each with a characteristic dark brown or black throat that gives the plant its common name. Blooming profusely from spring through autumn, Thunbergia alata adds a cheerful, tropical touch to gardens, fences, trellises, and hanging baskets. It thrives in full sun to partial shade and prefers well-drained, moderately fertile soil with regular moisture. Often grown as an annual in cooler climates, this vigorous vine can reach lengths of 2 to 3 meters, making it a popular choice for quick, colorful coverage and decorative vertical displays.
