juglone – GrowIt BuildIT

Black Walnut trees emit a toxic substance called Juglone that kills certain plants that grow near them [1]. However, not all plants are susceptible to Black Walnut Toxicity via Juglone poisoning. Knowing which plants can thrive along side Black Walnut trees is important to have a successful garden or flower bed. By thoroughly researching University and Science Journal publications, I've compiled a comprehensive list of Plants tolerant of Black Walnut Trees. There are over 200 species of vegetables, flowers, and trees that are not harmed by Juglone, the poison that is emitted from Black Walnut tree roots. The toxic Black Walnut substance, Juglone Black Walnuts that have been husked. Juglone has been documented as inhibiting, stunting, or damaging nearby plants for centuries. In fact the first record was nearly 2000 years ago, when Pliny the Elder noted that "The shadow of walnut trees is poison to all plants within its compass [3]". In addition to harming transplants, Black Walnut Trees can prevent or inhibit the germination or harm seedlings of various species [2]. I've compiled a complete listing of all known plants that are sensitive to the Black Walnut Toxin Juglone based on researching universities, government and other journal publications. This list contains all documented vegetables, flowers, trees and shrubs that are impervious to Black Walnut toxin known as Juglone.
