Plants can improve indoor air quality, and affect the work efficiency and subjective perceptions. However, the conclusions of existing experiments regarding how plants affect work efficiency are not uniform. To further explore this subject, this study designed five different working conditions, and selected a variety of “general tasks” and “tasks requiring concentration” as operational tasks. The effects of the plant arrangement and quantity on work efficiency were studied by analyzing the performance of subjects in different working conditions. The effects of the plants on the subjective perceptions were investigated using questionnaires. The experimental results show that the effects of plants on work efficiency were related to the nature of the work, the placement of the plants, and the number of plants. Plants had no effect on the efficiency of general tasks such as “symmetry breadth,” but had a positive impact on the efficiency of general tasks such as “operational breadth.” Moreover, by changing the arrangement and quantity of plants, the efficiency of general tasks could be increased by up to 19.1%. In contrast, plants placed within a coincident view had a negative impact on the efficiency of “tasks requiring concentration,” and the work efficiency could be reduced by up to 12.4%. In addition, plants could increase enthusiasm and willingness to work by 12.5% and 11.8%, respectively.
