Use big pieces. It may sound counter-intuitive, but petite furniture makes a small space seem tinier. A few oversize pieces, especially chairs, on the other hand, make it feel more generous than it actually is.
Keep the color range narrow. Use analogous colors—ones next to each other on the color wheel, such as yellow and yellow-green. Too many competing hues in a tight space are jarring.
Take advantage of vertical space. Hide it with a row of clumping bamboo. Then stick a bouquet of Balinese umbrellas in a pot to show off against the green background.
Reinforce your theme. Go for a lush look—giant leaves (elephant’s ear), bright plants (croton), and glamorous tropical flowers (orchids, bromeliads, ginger).
