Know Before You Grow: Invasive Plants
An invasive plant is one that is capable of moving aggressively into a habitat and monopolizing resources such as light, nutrients, water, and space to the detriment of other species.
A plant is Native if it has evolved and is adapted to local environmental conditions and is part of a natural community.
A plant is Non-Native if it has been introduced into a new location by human activity, either intentionally or by accident. It may or may not be invasive in a particular area so it is important to do your research before introducing a plant to your landscape.
Why worry about invasive plants?
Invasive plants often spread aggressively, reducing biodiversity, altering soil chemistry, and making it harder for beneficial plants, insects, and wildlife to thrive. They can also be difficult and costly to remove.
Why are they difficult and costly to remove?
Invasive plants often have aggressive growth habits, rapid reproduction, and the ability to spread through multiple methods, such as seeds, rhizomes, or runners. Many invasives establish deep or extensive roots systems, making manual removal labor intensive and requiring repeated efforts to prevent growth. Some species can even re-sprout form small root fragments, making complete eradication challenging.
Chemical control methods, like herbicides, may be necessary in some cases but require careful application to avoid harming desirable plants and the surrounding ecosystems. Additionally, ongoing monitoring and maintenance are needed to prevent re-infestation, increasing long-term costs and effort.
Common Invasive Plants in Landscaping
Trees and Shrubs
Mimosa or Silk Tree
Threat: Will spawn seeds everywhere in your yard and throughout your neighborhood. Once its established its nearly impossible to get rid of.
Native Alternative: Eastern Redbud or Downy Serviceberry
Privet:
Threat: Grows multiple trunks within an area forming a dense thicket that is very difficult to remove once established
Native Alternatives: Fragrant Sumac
Nandina:
Threat: Rapidly growing underground rhizomes that cultivate dense thickets that are very difficult to remove once established
Native Alternative: Oakleaf Hydrangea
Holly:
Threat: Spreads easily by seed. The plant can grow many suckers with deep roots. Hard to remove once it takes hold.
Native Alternatives: Arrowwood Viburnum
Burning Bush:
Threat: Forms dense thickets that crowd out native vegetation
Native Alternative: Ninebark
Butterfly Bush:
Threat: Doesn’t offer any benefits to pollinators, and is not a host to any butterfly species. Seeds spread rapidly out competing native plants
Native Alternative: Buttonbush
Vines:
Chinese Wisteria:
Threat: Rapidly grows and rapidly spreads through seed dispersion
Native Alternative: Clematis “Jackmanii”
English Ivy:
Threat: Rapid, dense growth that smothers native vegetation
Native Alternative: Golden Knee
Herbaceous Plants and Grasses:
Liriope Spicata
Threat: Spreads by Rhizomes to form dense mats that crowd out native species
Native Alternatives: Creeping Phlox or Plantain-Leaf Sedge
Do I only need to plant natives?
Not necessarily! While native plants are great because they support local ecosystems, require less maintenance, and are more adapted to your climate, you don’t have to limit yourself to them entirely. A good approach is to prioritize natives for their ecological benefits while also incorporating well-adapted, non-invasive plants that fit your design and functional goals. Just be mindful of avoiding invasive species that could outcompete native plants.
