The Ping'an tree (Cinnamomum kotoense) is a common indoor foliage plant with an auspicious meaning.

The Ping'an tree is an evergreen small tree of the genus Cinnamomum in the family Lauraceae, with the scientific name Cinnamomum kotoense. It is native to the Lanyu area of Taiwan, China. Because its name carries the auspicious meaning of peace and good fortune, and because of its neat shape and dark green leaves, it has become a very popular indoor foliage plant, often placed in living rooms, offices or storefronts to decorate the environment.

In appearance, the Ping'an tree has smooth bark and opposite leaves that are leathery and glossy. Young plants have a compact form and a good overall ornamental effect. After the leaves are rubbed, they give off a light fragrance similar to cinnamon, which is also a feature that distinguishes it from ordinary green plants.

In terms of care, the Ping'an tree prefers a warm, humid, semi-shaded environment. It fears cold and also dislikes strong direct sunlight. In spring and autumn, it can be placed in a position with bright scattered light. In summer, pay attention to shading and ventilation. In winter, it should be moved indoors to keep warm and avoid direct cold drafts. Watering should follow the principle of watering when the soil is dry and letting it dry between waterings; the pot must not retain water for a long time. When the air is dry, spray water on the leaves and the surrounding area to increase humidity, and during the growing season, a suitable supplement of dilute liquid fertilizer is enough.

In daily care, yellowing leaves and leaf drop in the Ping'an tree are mostly related to low temperatures, overwatering, excessively dry air or improper light. When abnormal leaves are found, first check the moisture of the potting soil and the placement position, promptly cut off dead leaves and adjust the environment, and the plant will generally gradually recover its growth.
