6. African Violet
African Violet is the perfect tree for the office. They respond very well to artificial light, often grown under artificial light. Their soft, translucent leaves and gorgeous flowers in a variety of colors will provide an enhanced mood. Research has shown that just looking at the delicate violet flowers of African Violet will produce small amounts of adrenaline, increase energy, and increase the flow of oxygen in the brain, helping you stay awake during the afternoon.
