The Harpeth River Watershed Association is greeting the spring planting season by urging people to use native species and be aware of invasive species that are present in the ecosystem.
Invasive plant species are plants growing outside of their native habitat range.
Siltgrass is a common invasive species.

They are most often introduced when they are planted in gardens or yards. Some of these plants are able to reproduce and spread rapidly causing potential harm to our ecosystem. These invasive plants can be harmful because they can out compete and overshadow our native species.

Volunteers from the Harpeth River Watershed Association participated in Weed Wrangle, a one-day, citywide, volunteer effort to help rescue our public parks and green spaces from invasive species through hands-on removal of especially harmful trees, vines and flowering plants. Weed Wrangle was started by The Garden Club of Nashville in 2015.
The following are a few of the most common in Middle Tennessee:
  • Common/Japanese/Chinese Privet
  • Japanese siltgrass
  • Kudzu
  • Japenese Honeysuckle
  • English Ivy
  • Winter Creeper

Experts suggest the following alternatives to non-native species that can grow and thrive out of control here:

Native Alternative
Chinese/Japanese Privet Inkberry or Devilwood
Common Privet Limerock Arrowwood
Southern Waxmrytle
Possumhaw Viburnum
Japanese Honeysuckle Southern Bush Honeysuckle
English Ivy Climbing Hydrangea
Winter Creeper Christmas Fern
