Cup of Gold

Cup of Gold Overview

Cup of Gold is a fast-growing tropical vine with very large yellow flowers. The blossom can reach up to about 9 inches wide, which makes it one of the more dramatic flowers in the Hawaii flower guide. Its name comes from the big golden-yellow bloom, which looks like a deep cup when fully open.

The flower is streaked with purple and has a sweet scent. In Hawaii, Cup of Gold grows best in humid places, especially rainforest-like areas where warmth and moisture support strong vine growth.

Flowers, Growth and Blooming Season

Cup of Gold is known scientifically as Solandra maxima. It is a climbing vine, so it needs room and support as it grows. In the right conditions, it can cover fences, arbors or sturdy garden structures with large leaves and bold flowers.

The main blooming season is in winter. That timing makes Cup of Gold especially noticeable because the large yellow flowers can brighten damp, green areas during the cooler part of the year. Its size, color and fragrance make it a memorable garden vine, but its fast growth means it needs space and maintenance.
