There are many benefits from having plants in the workplace. Not only do they make a better impression on visitors, and make it a much nicer place to work, they also offer many health benefits reducing the number of days absent taken by staff, for example:
Planted bowls and troughs can be very effective, as well as enhancing cabinets used as dividers. They can give you that welcome touch where there is no floor space.
It is considered good Feng Shui to have a plant next to every PC to enhance the balance and harmony in the office. They can even echo the large plants in the rest of the office.
