One thing I love most about North Carolina is its natural wonders. Stretching from Appalachia to the Atlantic, our state is teeming with biodiversity. More incredible is that some of our natural flora–like the world-famous Venus flytrap–are found nowhere else on earth. Called “endemic,” these plant species are native to a specific region and are found naturally only in that region.

Remarkable Plants that Call NC Home

North Carolina’s endemic plants are integral to our state’s ecological identity. These rare species evolved over many millennia by adapting to our region’s climates, soils, and elevations—creating unique ecosystems that are both fragile and fascinating.

Endemic plants are the building blocks of their habitats. They provide food and shelter to a range of wildlife, including essential pollinators. They also contribute to soil health and water retention, helping maintain ecological balance. The importance of biodiversity can’t be overstated. 

So… which species are endemic to the Tarheel State, you ask? Let’s dig in! 

In 2022, the NC Natural Heritage Program published this list of all plant taxa1 (including subspecies) that naturally exist within our state’s borders: 31 taxon in all. Take a look.

Plants, of course, don’t recognize state borders like humans do. “Near-endemic” refers to species that thrive mainly in North Carolina while brushing another Southern state or two. In 2014, ncpedia.org assembled a list of North Carolina’s 42 endemic and near-endemic plants that’s worth a read. 

A Few Fine Examples of NC Endemics

(Left) You can spot Heller’s blazing star (Liatris helleri) on ledges of precipitous cliffs in northwestern North Carolina, especially Grandfather Mountain’s southeastern slopes. (Right) The Venus flytrap (Dionaea muscipula) is one of the most well-known carnivorous plants. The NC Heritage Program names the primary threats to Venus flytraps as loss of habitat, fire suppression and lack of appropriate habitat management, and poaching.

I hope these endemic and near-endemic species give you an idea of how enamoring North Carolina’s rare, native flora can be:

Heller’s Blazing Star (Liatris helleri s.s.) – one of about 40 species in the genus Liatris
  • Description: A perennial wildflower that blooms striking purple flowers in late summer to early fall.
  • Range: Found primarily in the southern Appalachians. Only eleven known populations, all occurring in North Carolina’s Burke, Caldwell, Mitchell, Avery, Watauga and Ashe counties. 
  • Habitat: Shallow acidic soils on high elevation rock outcrops and ledges.
  • Fun Fact: Heller’s blazing star is considered fire-adapted, meaning that it does not benefit from the suppression of natural fire. (This makes sense for a native plant that acclimates to its natural environment.)
  • Conservation: Listed as NC Status T (Threatened). The NC Botanical Garden conserves this rare species. Learn more on The Center for Plant Conservation site and see the US Fish & Wildlife’s recovery plan.
  • Info source (search for species name) or this source for what’s written above
    • T means Threatened. A taxon that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range (Public Law 93-205 87 Stat. 884) source
Venus Flytrap (Dionaea muscipula) – near-endemic to North Carolina
  • Description: World-famous carnivorous plant that supplements its diet with insects and arachnids. Its “trap” consists of two hinged lobes at the tip of each leaf. Hair-like structures (trichomes) trigger the lobes to close when they sense prey.
  • Range: Endemic to an area in about an 80-mile arc around Wilmington, NC, which stretches into two counties in South Carolina.
  • Habitat: Acidic, sandy soil that seems very dry but the water table is not far below the plant.
  • Fun Fact: While illegal to collect from the wild, Venus flytraps can be ethically purchased from The NC Botanical Garden and other conservation organizations.
  • Conservation: Listed as NC Status T (Threatened). Read about the NC Heritage Program’s conservation efforts, as well as the “story map” created with NASA, a “remote sensing” project that identifies sustainable habitats for the Venus flytrap.
  • Info source: NC Plant Toolbox or this source (search for species name)

Pink-shell Azalea (Rhododendron vaseyi) – member of the heath family
  • Description: Deciduous shrub that shows pink flowers in spring. Typically grows 3 to 6 feet tall and has narrow, lance-shaped leaves.
  • Range: Endemic to the Appalachian highlands of North Carolina with a main center of distribution west of Asheville.
  • Habitat: Prefers moist, acidic soils in forested areas, often near streams and in the understory of hardwood forests.
  • Fun Fact: Pink-shell azalea was found growing in the wild in Massachusetts. While it’s not native to that state, it naturalized on the site of an abandoned nursery.
  • Conservation: Listed as NC Status SR-L (Significantly Rare–Limited), which means that “their fate depends largely on conservation here” in North Carolina.
  • Info Source: Center for Plant Conservation and Natural Heritage Program (use search)
Coastal Goldenrod (Solidago villosicarpa) – always found within 1,000 feet of an estuary
  • Description: This perennial plant has hairy stems and narrow leaves, producing bright yellow flower heads in late summer to fall.
  • Range: Only four known populations in Onslow and Pender counties of North Carolina; between 100 and 1400 individual plants comprise each population.
  • Habitat: Grows in wet, sandy soils, often in salt marshes, coastal grasslands, and disturbed areas.
  • Fun Fact: coastal goldenrod is currently found on sites that were previously logged. Three of the four known populations are located on the Camp Lejeune Marine Corps Base in Onslow County, NC.
  • Conservation: Listed as NC Status S1 (Critically Imperiled), at very high risk of extirpation in North Carolina. Read more about conservation efforts on the Center for Plant Conservation site.

Conservation of NC’s Endemic Plants

Endemic taxa are resilient, having adapted to their specialized environments over time. But because they’re rare–some species presenting only a few individuals or small populations–they can easily be wiped out. Threats to our native plants include:

  • Habitat loss to recreational and residential development
  • Trampling by hikers, climbers, and sightseers
  • Natural succession to invasive species
  • Collection and illegal poaching
  • Acid precipitation and other forms of atmospheric pollution that have been found to be concentrated at higher elevations in the southern Appalachians
  • Climate change

Here in North Carolina, we don’t yet know the damage incurred to our endemic plants (or animals) in October 2024 by Hurricane Helene. Some populations might have been devastated by storm damage or flood water. Other populations might spring back stronger; coastal goldenrod, for example, is documented to thrive where trees have been knocked down by hurricanes.

Conservation efforts are critical to preserving these unique plants. By protecting their habitats and raising awareness, we can help ensure that North Carolina’s endemic flora continues to flourish. Through conservation initiatives, botanical gardens, and community engagement, we can foster a deeper appreciation for these remarkable plants and the ecosystems they inhabit.

These organizations are just some that are active in conservation and education efforts:

North Carolina Plant Conservation Program (NCPCP), part of the North Carolina Department of Natural and Cultural Resources, works with partners like the NC Natural Heritage Program to protect rare and endangered plant species, including many endemic plants.

North Carolina Botanical Garden, located at the University of North Carolina at Chapel Hill, emphasizes the conservation of native and endemic plants through education, research, and horticultural practices. NCBG partners with The Center for Plant Conservation, whose plant database incudes many of our state’s rare endemic taxon.

US Fish and Wildlife Service (USFWS) collaborates with state and local agencies to protect endangered species, including endemic plants in North Carolina.

Conservation alliances like the North Carolina Wildlife Federation and The Nature Conservancy work on broader conservation that includes endemic plants.

Citizen science initiative programs like the North Carolina Native Plant Society engage the public in monitoring and documenting plant species can help conservation practices.

Research and educational programs at universities and research institutions like Duke, the University of North Carolina, and NC State University, conduct studies focused on endemic plants and how to increase the sustainability of their ecosystems.

How You Can Help Protect NC’s Endemic Plants

To Do in the Garden: November 2024

By Gary Crispell, NC State Extension Master GardenerSM volunteer of Durham County

(Left to right) The October surprise, or should we say November surprise, of the ACG is the New England aster (Symphyotrichum novae-angliae). Do you still have pumpkins and gourds hanging around through Thanksgiving? Each year an estimated 1.3 billion pounds of pumpkins and gourds end up in landfills. Consider adding them to your compost or find a local participating municipality accepting them for donation. See below for more on Earth-friendly ways to deal with your organic decorations post-holiday.1 (Image credit: Dan Mullem CC BY-NC-ND 2.0; Melinda Heigel)

How ‘bout that October? Except for precipitation of any sort, there was something for almost everyone—a little hot, a little cool, and some stereotypical October Piedmont North Carolina, NC State Fair weather. There haven’t been very many State Fairs in my memory without some honest to goodness rain. We’ve been blessed unless, of course, you were trying to grow plants which is sort of what we’re all about here. So, mixed blessings? I mean, as fantastic as this area is, it still ain’t Camelot, Guinevere.


(Left to right) The ACG is still providing blooms this November. The drought-resistant African marigolds prove their hardiness. When planting for fall color, you can count on the New England aster and pink muhly grass to provide late-season interest. (Image credit: Gary Crispell; Jim Robbins CC BY-NC-ND 4.0)

The Accidental Cottage Garden (ACG) is too stubborn to give in to the crazy droughty up and down weather. There are some tough characters out there. The toughest of which must be the gallardia (G. pulchella). It doesn’t know quit. The African marigold (Tagetes erecta) and the zinnias (Z. elegans) are also heat and drought tolerant along with the false vervain (Glandularia bipinnatatifida). (Somebody stayed up late naming that one!)


A delightful surprise this year is a lovely New England aster (Symphotrichum novae-angliae). It isn’t as erect as I might be as it was crowded in amongst some other things, and I didn’t become aware of its existence until recently. Next year. Most of the hardy ageratum (Conoclinium coelestinum) have succumbed to the drought and the shorter days. There are a couple of late-to-the-party purple cone flowers (Echinacea purpurea) and a stray black-eyed Susan (Rudbeckia hirta). The muhly grass (Muhlenbergia capillaris) are looking a little thin and wispy, but I attribute that to it being the first year in the ground for them. Enough about my garden, let’s talk about what we can do in yours in November.

Lawn Care

Well, if your lawn has survived “No Moisture November” the main task for November is keeping it relatively leaf free. Whatever your remove from the lawn should be composted or used as mulch. The leaves do not belong in the landfill (or the ditch out front, for that matter). Cool season lawns (tall fescue, bluegrass, perennial rye) will still need mowing at the 3½” to 4” height.

The leaf admonishment pertains here, also. If you renovated/overseeded your lawn this fall it will need watering until the drought is done with us. 1” per week minimum applied in two ½” applications is necessary to keep it going.

Fertilizing

Not this month. If your (FREE until the end of November here in NC) SOIL TEST indicates a need to raise the pH, apply the appropriate the proper amount of lime and incorporate it into the soil if possible. Lime doesn’t readily move through the soil and incorporating the lime gets to the roots where it is needed.

Planting: Yes, “Fall is for Planting”

Trees, shrubs, and ground covers planted now will have all winter and early spring to put down roots in order to better withstand next year’s drought periods. (They’re coming. Trust me.) Spring flowering bulbs can still be planted until the end of the month. Year-old asparagus crowns can be transplanted now.

Pruning

So, for years (decades, centuries?) pruning all the perennials back as the blossoms faded (Grandma kept a tidy garden!) has been gardening gospel. Well, that good news is now obsolete news. It seems that solitary native bees and other pollinators lay their eggs on/in and/or nest in those stems for the winter. So, cutting them is detrimental to the pollinator population. Ergo, don’t do it anymore (unless the HOA is going to place a lien on your house for leaving them unpruned). (I don’t suppose the “It’s winter interest”, argument will get you anywhere.) Dead or diseased wood can be removed from trees and shrubs. Make any cuts at the branch collar (flared end) to promote healing of the wound.

Spraying

Any pests still hanging around can be treated with an application of a horticultural oil that will smother adults, eggs, and all phases in between.

Other Fun-filled and/or Fantastic Fall Frolics

Take a leaf hike through somebody’s neighborhood or a state or city park. There is a plethora of opportunities nearby.


Invite friends and neighbors over for an evening around the fire pit. S’mores, hot
chocolate, cider, and donuts are about mandatory. Anything else is optional.

Do anything else you can think of to get yourself outdoors to enjoy these last user-friendly days of 2024.

May you have Thanksgiving bountiful enough to share.
