Cup of Gold Vine (Solandra maxima): Spectacular Golden Trumpets for Warm Climates

The cup of gold vine, also known as yellow chalice vine, is a vigorous, woody climber that produces enormous, chalice-shaped golden-yellow flowers up to 8 inches long. Native to Mexico and Central America, Solandra maxima blooms intermittently throughout the year in tropical climates, with a sweet, coconut-like fragrance that intensifies at night. Its leathery, dark green leaves provide a lush backdrop for the spectacular blossoms.

Cultivation and Support

This vine requires a sturdy trellis, arbor, or pergola to support its heavy growth. It prefers full sun to partial shade and rich, well-drained soil. Regular watering and feeding during the growing season promote vigorous flowering. In cooler regions (below USDA 10), grow in a large container and overwinter indoors in a bright, cool location. Prune after flowering to control size.

Caution and Uses

All parts of Solandra are toxic if ingested. Plant away from children and pets. The vine is ideal for creating dramatic focal points on walls, fences, or over entryways. Its night fragrance makes it perfect for moon gardens.
