If you're trying to figure out which type of orchid you have in your home, the best way to do it is by looking for identifying characteristics. First, assess whether the plant is an epiphyte or terrestrial. Epiphytic orchids typically grow on trees and other plants, while terrestrial plants are grown in soil like any other flower. Once you've identified this characteristic, inspect the shape of the leaves — some species will have flat leaves while others might be sword-shaped. Additionally, look at how many roots each plant has; most types of orchids only have a few large roots as opposed to smaller feeder roots that spread throughout a potting mix. Finally, take note of any blooms your plant may produce since different varieties will display distinct colored flowers depending on their genetic makeup and environment. With these simple steps in mind, it should become much easier to narrow down exactly what type of orchid you're dealing with!
