Allerton Garden (Lawa`i-kai) lies between the Pacific Ocean and the McBryde Garden in the Lawa`i Valley, on the south shore of the Hawaiian Island of Kaua`i. It is a garden paradise, transformed through time by the hands of a Hawaiian Queen, by a sugar plantation magnate, and most significantly by an artist and an architect. The endless possibilities found in this dramatic topography led to the creation of this masterpiece of garden art.

A series of garden rooms unfold between the Lawa`i Stream and the cliffs of the Valley. The sound of water is in abundance in pools, miniature waterfalls, and fountains. Statues grace this former estate and resonate with a European influence.

Towering rainforest trees with tall curving roots grow near bronze mermaids, a grove of swaying golden bamboo, a cut-flower garden, and tropical fruit trees. Here the focus is on landscape design, but among the plantings are botanically important species of the tropics, including varieties of palms, ki (ti), heliconias, and gingers.

Allerton Garden is managed by the National Tropical Botanical Garden for the Allerton Garden Trust.
