Don’t Hold Back. Planning and executing an indoor rainforest using artificial Palm trees isn’t for the timid at heart. Think dense and diverse plants and trees, exotic and dangerous species, and thick air you can cut with a knife. Think waterfalls, estuaries, and bold toucan colors. While you may not be able to procure replica parrots, your artificial Palm trees should be just as exotic and varied as the rainforest you’re aspiring to replicate. Like most endeavors, you’ll get out what you in. Building a rainforest with silk Palms is no exception.
