A luminous twist on the classic Black-Eyed Susan Vine, Thunbergia alata ‘White Halo’ produces crisp white, 2-inch flowers centered by black-as-midnight eyes. The contrast is clean, graphic, and wonderfully bright against lush green foliage, particularly in evening light or on a shaded patio.

This vigorous twiner grows about 6–8 feet in a season, quickly clothing trellises, obelisks, fences, arbors, and balcony railings. Without support, it can spill dramatically from a large hanging basket or container. The white flowers pair beautifully with blue salvias, pink annuals, orange accents, silver foliage, and tropical-looking companions, while hummingbirds investigate the long summer-to-fall display.

Give ‘White Halo’ full sun to part shade, rich well-drained soil, regular water, and slender support around which its stems can twine. Afternoon shade is helpful in the hottest inland gardens. It is usually grown as an annual where frost is expected but can behave as a tender perennial in mild Zones 9–11. Trim wandering stems whenever a denser, more contained curtain is wanted. Fast, floriferous, and far more elegant than a vine this easy has any right to be, it supplies instant vertical charm. Explore our Thunbergia collection.
