8 Invasive Plant Species Found in Big Box Stores That No One Should Be Buying

Walking through the garden section of a big box store can feel like stepping into a botanical paradise. Rows of vibrant flowers, lush greenery, and aromatic herbs entice shoppers with promises of a backyard paradise. However, lurking among these tempting displays are some unwelcome guests—plants that are not only invasive but can wreak havoc on local ecosystems.

You might wonder why big box stores would sell such troublesome plants in the first place. The answer is... well, nothing short of complex, involving supply chains, consumer demand, and sometimes plain old ignorance. But fear not! We’re here to shine a light on these green culprits and offer some eco-friendly alternatives that will keep your garden both beautiful and safe.

1. Autumn Olive

Autumn Olive is often sold for its fragrant flowers and edible berries, attracting wildlife and adding visual interest to gardens. However, this shrub is highly invasive, spreading aggressively and outcompeting native plants. It can alter soil chemistry, making it difficult for other species to thrive.

Big box stores might carry Autumn Olive because of its hardiness and multifunctional uses. Despite these qualities, its ecological impact makes it a poor choice for responsible gardeners. Instead, try planting Serviceberry (Amelanchier) or Spicebush (Lindera benzoin), which provide similar benefits without the invasiveness.

2. Japanese Barberry

Japanese Barberry is often marketed for its colorful foliage and compact size, making it a favorite for landscapers and gardeners alike. However, this plant can spread rapidly through seed dispersal, forming dense thickets that provide a haven for ticks and outcompete native plants.

The appeal of Japanese Barberry in big box stores is understandable—it’s attractive, hardy, and low-maintenance. Yet, its invasiveness poses significant risks. Instead, consider planting native shrubs like Winterberry (Ilex verticillata) or Ninebark (Physocarpus opulifolius), which offer both beauty and ecological benefits.

3. Norway Maple

Norway Maple is commonly sold in big box stores thanks to its rapid growth and attractive foliage. It’s often planted in urban areas for its shade and resilience. However, this tree has a dark side . It produces a dense canopy that shades out other plants and releases chemicals from its roots that inhibit the growth of nearby flora.

The widespread availability of Norway Maple is likely due to its adaptability and ease of care, but its ecological impact can be severe. For a less invasive option, consider the native Sugar Maple (Acer saccharum) or Red Maple (Acer rubrum), which offer similar beauty and benefits without the harmful side effects.

4. Chinese Wisteria

Chinese Wisteria is known for its stunning cascading flowers that create a whimsical, fairy-tale ambiance. However, this vine can easily become a gardener’s nightmare. Its vigorous growth can strangle trees and shrubs, and it’s notorious for destroying structures with its woody stems.

Big box stores might stock Chinese Wisteria because its dramatic blooms make it a popular ornamental plant. Its invasiveness, however, makes it a poor choice for conscientious gardeners. Consider opting for native alternatives like American Wisteria (Wisteria frutescens) or the fragrant Climbing Hydrangea (Hydrangea anomala petiolaris) instead.

5. Purple Loosestrife

Purple Loosestrife is often admired for its striking purple spikes and long blooming season. However, this beauty is a beast when it comes to wetlands. It forms dense stands that crowd out native plants, altering water flow and degrading habitats for aquatic life.

Despite its ecological dangers, Purple Loosestrife may be sold in big box stores due to its visual appeal and hardiness. Luckily, there are plenty of non-invasive alternatives such as Blue Vervain (Verbena hastata) or Joe-Pye Weed (Eutrochium purpureum) that provide similar color and texture without the environmental impact.

6. Bamboo

Bamboo might evoke images of serene Asian gardens, but in reality, certain species can be highly invasive. Rapidly spreading through underground rhizomes, bamboo can quickly take over gardens and even crack through concrete. Its resilience and rapid growth make it nearly impossible to control once established.

Big box stores may sell bamboo because it’s durable and versatile, appealing to those looking to create privacy screens or exotic landscapes. However, the damage it can cause makes it a risky choice. Instead, look to clumping varieties like Fargesia or ornamental grasses like Feather Reed Grass (Calamagrostis acutiflora) for a safer alternative.

7. English Ivy

English Ivy is another classic example of a plant that looks innocent enough but can cause serious harm . This evergreen vine is often marketed for its ability to create lush, green ground cover and climb walls and fences. However, its aggressive growth can smother trees and shrubs, compromising their health and stability.

The popularity of English Ivy in big box stores can be attributed to its versatility and low maintenance requirements. Unfortunately, once it escapes cultivation, it can be extremely difficult to eradicate. For those seeking a safe alternative, consider planting Creeping Jenny (Lysimachia nummularia) or Wild Ginger (Asarum canadense), which provide similar coverage without the invasive tendencies.

8. Japanese Honeysuckle

Japanese Honeysuckle is a fast-growing vine that’s often found in the garden section, boasting fragrant white and yellow flowers. While its sweet smell and aesthetic appeal make it a popular choice, this plant is a nightmare for native species. It aggressively takes over areas, choking out local flora and disrupting habitats for insects and birds.

Big box stores might carry Japanese Honeysuckle because it’s easy to grow and maintain, making it a hit among novice gardeners. However, its invasiveness means it can spread rapidly, overshadowing more delicate plants and reducing biodiversity. Instead, consider planting native alternatives like Trumpet Honeysuckle (Lonicera sempervirens) or Virginia Creeper (Parthenocissus quinquefolia), which offer similar beauty without the ecological risks.

While big box stores offer an easy and often cheaper way to purchase plants, it’s important to be mindful of the potential ecological impact of some popular choices (especially since your local Lowes or Home Depot isn't likely to warn you ahead of time!)

Invasive plant species may provide short-term beauty and low-maintenance solutions, but the long-term consequences can be devastating for local ecosystems. By opting for native or non-invasive alternatives, gardeners can enjoy a beautiful, sustainable landscape that actually supports biodiversity and environmental health (making that a win for everyone).
