Introduction

Black walnut trees are known to produce a chemical compound called juglone, which can be toxic to many plants. As a result, it can be challenging to find suitable plants to grow underneath a black walnut tree without them dying. In this article, we will explore which plants are evasive and can grow successfully under a black walnut tree.

Perennial Plants

Perennial plants are a great option to grow under a black walnut tree as they can survive for many years. However, not all perennial plants are suitable for this environment. One evasive perennial plant that can grow under a black walnut tree is the hosta. These plants are highly adaptable and can tolerate the toxicity of juglone. Another evasive plant is black cohosh. This plant has flowers that bloom in the summer and thrive in the shaded areas found under a black walnut tree.

Annual Plants

Annual plants are another option to grow under a black walnut tree. These plants complete their life cycle in one growing season, so they often need to be replanted each year. One evasive annual plant is the impatiens. They are known for their bright colors and ability to thrive in shaded areas. Another option is the marigold. These plants have a strong scent that can mask the odor of the juglone produced by the black walnut tree. It is essential to note that marigold plants only provide a short-term solution as they are an annual plant.

Vegetable Plants

Vegetable plants are a great way to utilize the space under a black walnut tree while also producing fresh produce. However, it can be challenging to find varieties of vegetable plants that can tolerate the toxicity of juglone. One evasive vegetable plant is the asparagus. This plant is a perennial vegetable that can produce a yield for up to 15 years. Another evasive option is the sweet potato. These plants are known for their ability to grow in harsh environments and can also tolerate the toxicity of juglone.

Fruit Trees

Fruit trees are a great option to grow under a black walnut tree as they can provide fresh fruit while also adding beauty to the space. However, it is essential to be mindful of the type of fruit tree that is planted as some varieties are not evasive. One evasive fruit tree is the pear tree. Pears are relatively tolerant of juglone, making them an excellent option. Another evasive fruit tree is the pawpaw. This tree produces a tropical-tasting fruit and can tolerate the toxicity of juglone.

Conclusion

Growing plants under a black walnut tree can be challenging due to the toxicity of juglone, but there are still many evasive plants that can grow successfully in this environment. Perennial plants such as hosta and black cohosh, annual plants such as impatiens and marigolds, vegetable plants such as asparagus and sweet potatoes, and fruit trees such as pear and pawpaw are all great options to consider. By selecting evasive plants, the space under a black walnut tree can be utilized and turned into a thriving garden.
