Lavalle corktree
IOverview
Overview
Lavalle corktree (Phellodendron lavallei), a deciduous tree native to the forests of Amur, China North-Central, China Southeast, Inner Mongolia, Japan, Khabarovsk, Korea, Kuril Islands, and parts of Vietnam, is a versatile and ornamental addition to gardens. This tree thrives in full sun with moist, well-draining soil that can be light (sandy), medium, or heavy (clay), and is hardy in zones 5-9, reaching a height of about 10 meters. Its distinctive feature lies in the edible quality of its fruit, making it not only an ornamental addition to gardens but also a valuable source of sustenance. Ethnobotanically, the plant has been traditionally used in Chinese medicine to support immune function, with a decoction of bark potentially helping to modulate inflammatory responses and enhance the body's defense mechanisms. Additionally, the tree has been introduced into Bulgaria, Connecticut, Delaware, Illinois, Maryland, Massachusetts, New Jersey, New York, Ohio, Pennsylvania, Québec, Romania, and Tadzhikistan, where it can be cultivated for its various utility purposes, including cork, dye, pest control, oil, and lumber. While the plant has traditional uses, PlantSage presents these as ethnobotanical contexts and not as medical advice.
