What to Plant Under Oak Trees in Illinois

Oak trees are a common sight throughout Illinois, providing not only shade but also an aesthetic appeal to any landscape. However, their extensive root systems and dense canopies can make it challenging to find appropriate plants to grow underneath them. Fortunately, several species of plants can thrive under the shade and compete against the root systems of oak trees. Here are some of the best plants to consider planting under oak trees in Illinois.

Hostas

Hostas are popular plants for growing in shady areas, making them an excellent choice for planting under oak trees. They have lush, green foliage that forms mounds, that bloom in a variety of colors like purple, white, and blue. Hostas are easy to grow, and their dense foliage helps to control soil erosion, while also adding visual interest to the area. They prefer soil that is well-drained and slightly moist, making the area around the base of the oak tree ideal for their growth.

Ferns

Ferns are another plant that thrives in shady areas, and their feathery fronds provide a beautiful contrast to the rough, textured bark of the oak tree. There are several varieties of ferns to choose from, such as the Christmas fern, Lady fern, and the Maidenhair fern. Ferns prefer well-drained soil and thrive in moist surroundings, and planting them under oak trees can help to retain soil moisture and prevent runoff.

Wildflowers

Wildflowers are versatile and can survive in various conditions, making them an excellent choice for planting under oak trees in Illinois. They can improve the aesthetics of the area, especially when planted in clusters, adding pops of color to the otherwise green and brown surroundings. Wildflowers like columbine, coneflower, and wild geranium are ideal for planting under oak trees because they are tolerant of shade and can thrive in poor soil. They are low maintenance and require minimal watering and fertilization.

Azaleas

Azaleas are a beautiful flowering shrub that prefers partial shade, making them a suitable option for planting under oak trees. They are admired for their colorful, trumpet-shaped flowers that bloom in spring, adding a burst of color to the sometimes monotonous shade of the oak tree. Azaleas like moist soil with slightly acidic pH levels and require regular watering to ensure optimal growth.

Conclusion

Choosing the right plants to grow under oak trees in Illinois can be challenging, but it is essential to find species that can happily coexist with the extensive root system of the oak tree. In this article, we have outlined some of the best plants to consider planting under oak trees, with notable mentions of ferns, wildflowers, hostas, and azaleas.
