***Solandra maxima*** is a [flowering plant](/source/Flowering_plant) in the family [Solanaceae](/source/Solanaceae).[1] It is also known as **cup of gold vine**, **golden chalice vine**, **Copa de Oro**, or **Hawaiian lily**, is a vigorous [vine](/source/Vine) which is endemic to [Mexico](/source/Mexico) and [Central America](/source/Central_America). It has very large yellow flowers and glossy leaves. It is often planted as an ornamental plant.

## Description

It is a fast-growing, 12 m (39 ft) tall climbing vine, occasionally reaching as much as 50 m (160 ft) long,[2] which is often pruned back in cultivation to a shrub with overhanging twigs. The leaves are alternately arranged, broad-elliptical to oblong, 5-18 × 2-9 cm in size, leathery, glossy on top and usually short-[acuminate](/source/Acuminate). All parts of the plant are poisonous.

### Flowers

The funnel-shaped flowers are usually solitary. The [calyx](/source/Calyx_(botany)) is 5-8 cm long, pentagonal and consists of three to five cusps. The [corolla](/source/Petals) is 15-24 cm long and consists of large, rounded, 8-15 cm wide lobes. The flower is creamy white to light yellow at the start of flowering and changes color to ocher to orange during flowering. Violet or brown bands run deep into the flower tube across the center of the corolla. Five [stamens](/source/Stamen) protrude from the flower tube. The flowers open in the evening, exuding a pungent scent. This attracts bats as pollinators. The fruit is round, up to 7 cm large [berry](/source/Berry) on which the sepals are preserved.
