What Shrubs Can You Plant Under a Black Walnut Tree

Black walnut trees are a beautiful addition to any landscape. These trees can grow up to 80 feet tall and have a broad, spreading canopy. However, while these trees are majestic, they pose a problem to plants growing beneath them. Black walnut trees produce a compound called juglone, which is toxic to many plants. This can make it challenging to find shrubs that can thrive under a black walnut tree. In this article, we explore some of the shrubs that can survive under a black walnut tree.

Barberry

Barberry is a shrub that can grow to be around six feet tall and seven feet wide. It is a hardy plant that can withstand a variety of soil conditions. It produces attractive red berries in the fall and has foliage that changes color throughout the year. It is also resistant to juglone, making it an excellent choice for planting under black walnut trees.

Japanese Yew

Japanese yew is an evergreen shrub that can tolerate a range of soil conditions. It can grow to be up to 20 feet tall and is commonly used as a screening or hedge plant. It can also grow in the shade, making it an ideal choice for planting under black walnut trees. It is also resistant to juglone, which makes it a great option for any garden.
