Tropical plants grow in warmer more humid environments. These places experience constant temperatures above 65 degrees and never experience temperatures below freezing. Some examples of tropical plants are Bromeliads, Orchids, and a majority of the foliage plants available in the market today. They are great additions to your home or terrarium when you're looking for a plant to provide some color, texture, height, and or impact to your setup. Tropical plants will grow best in moderate to high light environments, humidity between 50 - 80%, well drained soil, and regular watering / fertilizing.
