Introduction

Black walnut trees are known to produce a chemical called juglone that can be toxic to certain plants. This raises the question of what plants can we plant around a black walnut tree? In this article, we will explore the types of plants that can coexist with black walnut trees.

Plants that can tolerate juglone

Although juglone can inhibit the growth of certain plants, some species are known to be tolerant of this chemical. Examples of plants that can grow around black walnut trees include Japanese yew, astilbe, ferns, and hostas. These plants are able to metabolize juglone and are not affected by its toxic effects.

Shrubs and small trees

Another option for planting around black walnut trees is to choose shrubs and small trees that are also juglone tolerant. Some examples of shrubs that thrive around black walnut trees include the Red Chokeberry, Summersweet Clethra, and the Sweetshrub. Small trees such as the American hornbeam, the red maple, and the Kentucky coffee tree are also known to be juglone tolerant.

Plants that add to the aesthetics of your garden

There are several plants that can add to the beauty of your garden and can also grow comfortably around a black walnut tree. Examples of these include the Purple Coneflower, the Black-eyed Susan, and the Joe Pye Weed. These plants are not only visually appealing but also attract pollinators like bees and butterflies to your garden.

Plants to avoid planting around a black walnut tree

While it's important to know which plants can thrive around a black walnut tree, it's also good to be aware of plants that should be avoided. Some plants are highly sensitive to juglone and can be killed by its toxic effects. Examples of these plants include eggplant, potatoes, and tomatoes.
