A study in 1998 by Larsen et al. found that adding greenery to the office increased perceived attractiveness and comfort for employees. The more plants present, the higher the attractiveness. Other studies by Shibata et al. (2002) and Shoemaker et al. (1992) also supported the idea that offices with plants make a more desirable workplace. In 1972, Maslow and Mintz conducted an early study suggesting that the aesthetic quality of a room, influenced by plants, can affect people’s moods, leading to increased energy and well-being.
Indoor plants have a significant impact on employee performance, especially for those experiencing high stress levels (Fjeld et al., 1998; Kim & Mattson, 2002).
