Exotic plants, also called alien plants, nonnative plants, or introduced plants, both are cultivated and grow in the wild. Before you decide to grow some exotic plants, you need to keep in mind about pros and cons of exotic plants first. Growing exotic plants can be rewarding because of their vibrant flowers and unique shapes, but the plants will not thrive without hard work and consistent care. Most exotic plants require constant attention to thrive, including maintaining a perfect environmental balance of the plants’ temperature, light and humidity. They also require the grower to research the plant to ensure it is being properly fed and cared for. A benefit of growing exotic plants is that they often offer the most colorful blooms and unusual shapes of the plant world. For example, the ribbon bush is an exotic plant that resembles a tapeworm, with flat, segmented stems, and it grows up to 10 feet (3 m) tall.
A disadvantage of growing exotic plants is that each species has different growing requirements, requiring plenty of research whether a gardener plans to grow one or several different species. Orchids, for example, require an environment which simulates their natural environment to a large degree. Those native to the tropics and high altitudes, for example, prefer a high humidity of 80 to 90 percent, and orchids from warm climates need steady moisture and plenty of circulating air.
