The Tropical Vine Terrace is an open grassy space with beautiful views of Mount Nevis and the Rainforest Conservatory on one side and the Gardens and Caribbean Sea in the distance on the other. Perfect for events, the charming bronze Mermaid Fountain is sited in the middle of the terrace which is surrounded by arbors of beautiful tropical vines. One of the most spectacular is the Jade Vine (Strongylodon macrobotrys) which has hundreds of metre-long, sea-green-coloured flowers. It is rare in cultivation and endangered in the wild.

The flowering vines have pride of place on the Tropical Vine Terrace. Here the entangled sky-blue blossoms of the Clock Vine (Thunbergia grandiflora), native to South East Asia, mingle with pink cascades of the Cross Vine (Bignonia capreolata) from tropical North America and the purple-flowered Glow Vine (Saritaea magnifica) from South America. Strolling through the Tropical Vine Garden you can also examine the strange purplish-brown fabric-like flowers of the Brazilian Calico Vine (Aristolochia elegans) and its beautiful green heart-shaped leaves.

Perfuming the night air around the Vine Terrace are the scented blossoms of the Wax Flower or Stephanotis (Stephanotis sp.) and the scented Rangoon Creeper (Quisqualis indica). Another spectacular vine when in full bloom, the Rangoon Creeper is covered with large trusses of showy tricolored flowers which open white, change to pink, then red over a 2-3 day period. Bougainvillea gracefully drapes the fences around the terrace.
