Four Invasive Plants to Avoid (And What to Plant Instead)

Years ago, my garden taught me surprising lessons about environmental responsibility. Like many beginners, I started planting without understanding the difference between native species – plants that have been part of our ecosystem since before European settlement – and invasive ones that can wreak havoc on our environment. I know now that invasive plants are more than just foreign visitors; they can overwhelm native species, disrupt wildlife habitats, and alter our local ecosystems. Today, I want to share how we can become better stewards of our environment by making mindful choices in the garden.

Pictured above is the Burning Bush also known as the Euonymus alata

Consider the Burning Bush (Euonymus alata), a landscape shrub cherished for its spectacular autumn display of crimson foliage. While its fall colors might catch your eye, Burning Bush poses a serious threat to our native ecosystems. The plant's prolific seed production and rapid growth allow it to establish dense thickets that crowd out native vegetation in natural areas.

Pictured above is the Arrowwood (Viburnum dentatum)

A better alternative is the native Viburnum, particularly the Arrowwood (Viburnum dentatum) or Blackhaw (Viburnum prunifolium). These versatile shrubs offer vibrant fall colors similar to Burning Bush and with greater ecological benefits. In spring, they produce clusters of delicate white flowers that attract native pollinators. The flowers develop into berries that sustain local birds through fall and winter. You can plant them individually or group them to create an effective privacy screen.

Pictured above is the Japanese Barberry (Berberis thunbergii)

Japanese Barberry (Berberis thunbergii) represents another common but problematic landscape choice. This Asian native might seem appealing for its compact size and tolerance to various conditions, but its dense growth creates perfect hiding spots for ticks, which can carry Lyme disease. Its thorny nature makes Japanese Barberry particularly unpleasant to manage.

Pictured above is the Ninebark (Physocarpus opulifolius)

Instead, consider the native Ninebark (Physocarpus opulifolius) or Red Twig Dogwood (Cornus sericea). Ninebark offers year-round interest with its exfoliating bark, spring flowers, and diverse leaf colors. Red Twig Dogwood, on the other hand, provides dramatic winter interest with its colorful stems, spring blooms, and fall berries that support native wildlife.

Pictured above is the Orange Daylily (Hemerocallis fulva)

The common Orange Daylily (Hemerocallis fulva) might seem like a carefree choice, but this aggressive spreader earned its nickname "ditch lily" for good reason. Its root system makes it nearly impossible to eliminate once established, and it can quickly colonize and displace native vegetation in natural areas.

Pictured above is the Black-eyed Susan (Rudbeckia hirta)

A beautiful native alternative is the Black-eyed Susan (Rudbeckia hirta). This cheerful perennial provides similar upright growth and bright colors and serves as a vital food source for native bees and butterflies. During winter, its seed heads offer essential food for birds during scarce times.

Pictured above is the Miscanthus Grass also called Chinese Silver Grass

Finally, let's address Miscanthus Grass, often called Chinese Silver Grass. Despite its popularity and undeniable visual appeal, this grass can become a maintenance nightmare. Its aggressive growth habit often requires heavy machinery for removal, and escaped plants can establish themselves in natural areas, forming dense stands that exclude native vegetation.

Native Switchgrass (Panicum virgatum) offers all the drama without the environmental concerns. This architectural grass provides vertical interest and movement in the garden while supporting local ecosystems. Modern cultivars like 'Shenandoah' with its red-tipped foliage, 'Heavy Metal' with its blue-gray leaves, and 'Northwind' with its strictly upright form, offer options for any design preference. Additionally, switchgrass supports native birds and serves as a host plant for several butterfly species.

For years and years, native plants have evolved in perfect harmony with our local conditions and wildlife partners. The choice between native and invasive is a choice to protect and foster that harmony and to shape the future of our environment.
