Plant tropical vegetation in your outdoor environment. For instance, palm trees, hibiscus and birds of paradise planted around your yard will add color, brightness and a tropical feel. Choose plants that can be grown in your particular area; check the USDA growing zones for each plant or tree you are considering. Plant your vegetation in colorful containers as well as in the ground for added style.
Place tropical-themed furniture around the environment. One of the best ways in which to evoke an island theme is to incorporate furniture that is comfortable, welcoming and all-natural into the environment. Tie a hammock in between two trees and utilize outdoor wicker or tropical-themed lounges, chairs and love seats. Make sure all surfaces can withstand the weather in your locale.
Place a fish pond in your outdoor environment. Ponds add a touch of the tropics to most any environment, especially if bright, vibrant fish are swimming inside. Add a few koi fish to your pond and surround it with large, natural stones.
Incorporate a water feature into your yard. Fountains create the relaxing sound of water that is found in many tropical landscapes. Place tropical plants around the base of the fountain or float tropical flower buds in the water.
Place lighting elements in your outdoor environment. Tropical lighting fixtures can evoke an island theme and will make your yard more inviting in the evening. Candles and tiki torches contribute to the effect.
