More information about invasive and native plants
Invasive plant species can be found just about anywhere these days, from your local garden center to natural areas. In fact, many of the plants that are currently invasive in our natural areas got here because people use them in their yards' landscaping. Do you know which plants are invasive?
If you need help with this, you could schedule a personal consultation, or ask Carrie to come speak to your group and teach you how to identify them. Or, you could go to websites like these that have lots of useful information:

Dealing with invasive plants
The most important thing to do is to try to prevent them from spreading further! Do this by cutting off all the flowers and fruits, putting them in the garbage so they will be sent to and covered deeply in the landfill. DO NOT put them in your compost pile! They will sprout and grow.
When removing invasive plants, it is important that you remove or kill the roots of the plant. If the roots remain alive in the soil, the plant will keep sprouting back over and over again. Once you have removed the roots from the soil, make sure they do not touch soil again, or they may actually re-root themselves and grow back. You can put them in the garbage, or simply make sure they die. I accomplish the latter by either spreading them out on a concrete surface or hanging them up in other vegetation so the roots will dry out and die.
The native plant species you put in your yard should be dictated by several factors, for example, the ecological zone are you in, whether the area you want to plant is in the sun or shade, and if the area is at the top of a hill, the bottom, or on a slope.

There are many good groups out there from which you can learn a great deal. The N.C. Native Plant Society is a very active, friendly group of folks. They have a website, Facebook pages, and regular meetings from which to learn all kinds of information. Another Facebook group from which you can learn a good deal is Pollinator Friendly Yards.
Here are some other resources from which you can learn about the plants native to your area:
The N.C. Extension Gardener Plant Toolbox
The Lady Bird Johnson Wildflower Center
The Biota of North America Program
If you need help figuring out how to select the most appropriate plants for your landscaping or reconciliation project, you could schedule a personal consultation, or ask Carrie to come speak to your group and teach you how to identify them.
Obtaining native plants for your landscape
It is not always easy to find the native plants you want for your project. But there are more nurseries propagating and selling native plants than ever before-- it is much easier now than it was a decade ago! There is now a "For the Birds and the Bees" native plant nursery and there are many others in North Carolina.
The North Carolina Native Plant Society keeps a list of nurseries in our area that sell native plants. You can find that webpage here. The NC-NPS has a plant sale every summer at its Annual Meeting. At the 2024 meeting, there were well over 200 different species of plants for sale! I encourage you to join your local native plant society. You will find lots of helpful people, many of whom are glad to share seeds with others.
You may find a few cultivars of native plants for sale at your local garden center. If you are not sure whether a certain plant is native to your area, one of the best ways to determine that is to go to the webpage for The Biota of North American Program. At the left is a link by which you can search for plants by genera. When you find the name of the genus you're looking for, click on that to obtain maps showing the areas where all the species in that genus are found. They are color-coded according to whether they are native or not.
