Horticultural therapy in Taiwan for more than 20 years, and it is still not understood by the public. With 12 kinds of plants common in Taiwan at low altitude, easy to grow, purifies the air, and eliminates germs as a basis for an extension, we made a horticulturally therapeutic planting interactive box for 6 kinds of plants. Since it is necessary to note the planting date and observe plants' growth, so we make a monthly calendar. We deeply understand the needs of horticultural therapy in Taiwan and hope to lead the public into horticultural therapy through theory and practice.
