How to Identify Native and Non-Native Plants in North Carolina

Updated

The North Carolina Native Plant Society (ncwildflower.org) treats plant identification as the first practical step toward conservation: once you know whether a plant is native or introduced, you can decide what to keep, remove, or plant. The site offers a native plant and tree gallery with detailed photos and search tools, an invasive non-native species list, and book recommendations. Use these resources if you want to survey your yard, confirm a plant you found on a hike, or plan a native garden.

Why identification comes first

According to the Society, identifying both native and non-native plants is "the first step to moving in the right direction." The reasoning is straightforward:

  • Native plants are described as the cornerstone of North Carolina's biological diversity, providing food and shelter for native animals and insects.
  • Non-native invasive species compete with those natives, so knowing which is which tells you what to protect and what to manage.
  • Gardeners who can tell the difference can choose native species deliberately instead of by guesswork.

Tools the site provides

Native plant and tree gallery

The gallery is the main identification tool. It includes detailed photos and search tools, and you can browse it or search it directly. This is the place to start when you have a plant in hand and want to confirm its identity and native status.

Invasive, non-native species list

A separate list covers invasive, non-native species. Check a plant here when you suspect it is introduced and potentially harmful — this is the list to consult before deciding to remove something.

Books about native plants

The Society also points to books on native plants as a reference option, useful when you want more depth than a gallery entry provides.

Species without pictures

The site notes there are species without pictures, so an entry missing a photo does not mean the plant is absent from the state — it may simply be undocumented in the gallery.

A practical identification workflow

  1. Photograph the plant — whole shape, leaf arrangement, flower or fruit, and bark or stem.
  2. Search the native plant and tree gallery using the site's search tools and compare against the detailed photos.
  3. Cross-check the invasive, non-native species list if the plant does not match a native entry.
  4. Confirm with a book when the gallery entry is thin or the species has no picture.
  5. Decide and act — keep and propagate natives, and manage confirmed invasives according to your own site conditions.

What to expect at each step

  • The gallery search returns photo-based entries, so your photo quality directly affects how confident the match is.
  • The invasive list is a screening tool, not a verdict on every non-native plant — many introduced plants are not invasive.
  • Books fill gaps the gallery leaves, particularly for species listed without pictures.

Common sticking points

  • Similar-looking species. Photo galleries can be ambiguous between closely related plants; use multiple photos (leaf, flower, habit) rather than one.
  • Missing pictures. Because some species lack images, absence of a photo is not evidence of absence.
  • Native vs. non-native is not the same as invasive vs. benign. The site keeps the invasive, non-native list separate from the native gallery for this reason.
  • Regional variation. North Carolina spans several plant hardiness and habitat zones, so a plant native in one part of the state may not be appropriate in another.

Where this fits into the bigger picture

Identification feeds directly into the Society's other offerings. Once you know your plants, the site's gardening resources — recommended plants and trees, landscaping tips, printable handouts, habitat certification, how to collect wild seeds, and a nursery finder — become usable. The Society also offers four funding sources for projects that support its mission: the Shinn Scholarship Fund, the BW Wells Grant, and the Alice Zawadzki Land Conservation fund among them, with details available through its grants and scholarships page.

If your goal is simply to know what is growing in your yard, start with the gallery and the invasive list. If your goal is to act on what you find, move next to the gardening and habitat certification resources.
