Psychological studies have shown, in fact, that the presence of indoor plants in homes and offices tends to improve human relationships and even worker productivity. Most begin to look ratty within weeks. In response to the problem of caring for indoor plants, many firms market plastic or silk replicas of popular foliage plants. Silks and plastics just don't do the job for people. Our phonies are so realistic relative to the environment that people tend to react to them as they would real, living, natural plants.

Most people have to take a second look to determine that, in truth, they are not living plants. Hidden in the pot, however, are controls which move the foliage, alter its appearance according to a pre-programmed set of rules based on time between watering or temperature changes. Still, they have to be watered AND dusted.
