The same goes for artificial plants as techniques have improved so much that it is often difficult to spot the difference between real and artificial. With certain flowers like orchids, the texture of the petals are made to feel so realistic that to an untrained eye, it can be impossible to tell the difference.
The materials used to make artificial plants and flowers are also no longer limited to silk. Some may be made using fire retardant materials and those intended for outdoors are sealed with a layer of UV protection to increase longevity. For certain artificial trees, the bark can also be made using real wood that have been treated, giving them an even more realistic appearance.
