Cup of gold, sometimes called chalice vine, is a heavy, thick stemmed tropical liana with large shiny leaves and large bell shaped golden yellow flowers. The thick and woody ropelike stems branch frequently and root at their nodes, and can run for more than 200 ft (61 m), clinging with aerial rootlets and scrambling over everything in the way. The evergreen leaves are leathery, about 6 in (15.2 cm) long and elliptic, with prominent lighter colored midribs and lateral veins.
The flowers are truly spectacular, shaped like a chalice, 6-10 in (15.2-25.4 cm) long, flaring open to 4-7 in (10.2-17.8 cm) across. The five lobes of the corolla are reflexed, and each lobe is marked with a narrow purplish brown ridge on the inside. The flowers start out yellow and turn deeper golden as they age. They are fragrant, especially at night, with a scent reminiscent of coconut. Cup of gold blooms intermittently through the year, but mainly in the winter dry season.
The fruits, rarely seen in cultivation, are round berries, about 2 in (5.1 cm) in diameter.
There are eight species of chalice vines, and they often are confused in the trade. Solandra maxima is the most common species in cultivation and vines offered as S. guttata and S. grandiflora may in fact be this one. The differences are subtle.
Usage
Cup of gold is often grown on large pergolas or trellises, or trained to grow up the side of a house where the spectacular flowers can spill down the walls over windows and doorways. Tolerant of salt spray and salty soils, all the chalice vines are excellent for seaside gardens. This is a large, rampant grower which requires plenty of space and a strong support.
