Nandina: South Carolina's Invasive Ornamental and How to Manage It

What Nandina Is and Why It Matters in South Carolina

Nandina domestica, commonly called heavenly bamboo or sacred bamboo, is a woody shrub originally from Asia that has become invasive across South Carolina. It is not actually bamboo—it is a member of the barberry family—but it resembles bamboo in its upright growth and feathery foliage. The plant produces small white flowers in spring and bright red berries in fall and winter, which made it popular in South Carolina landscapes for decades. Those same berries spread the plant into natural areas, where it now crowds out native understory plants and reduces habitat for wildlife.

Nandina matters to land surveyors and property owners because it spreads aggressively on disturbed land, along property lines, and in areas recovering from clearing or construction. Understanding how to identify it and what removal methods work is essential for anyone managing South Carolina land—whether for conservation, development, or restoration. The plant is now listed as a prohibited invasive species in South Carolina, meaning new sales are banned, though established plants on private property are not yet subject to removal orders.

Key Takeaways

• Nandina is a woody shrub with feathery compound leaves, small white spring flowers, and red berries that spread it into wild areas across South Carolina.
• The plant is now prohibited for sale in South Carolina because it crowds out native plants and reduces wildlife habitat in natural areas.
• Removal requires cutting stems below ground level and treating fresh cuts with herbicide, or repeated cutting over several growing seasons to exhaust the root system.
• Small infestations can be hand-pulled or dug out; larger patches need chemical treatment or professional removal to prevent regrowth.
• Prevention on your property means avoiding planting nandina and removing volunteer seedlings before they establish.

How to Identify Nandina on Your Property

Nandina grows as an upright, multi-stemmed shrub typically 4 to 8 feet tall, though it can reach 10 feet or more. The leaves are compound and feathery, arranged in a lacy pattern along the stems, and they turn reddish or bronze in fall and winter—a feature that made the plant attractive to homeowners. The stems are smooth and woody, ranging from green to reddish-brown depending on age and season.

In spring, nandina produces small white or pale pink flowers clustered at the branch tips. By late summer and fall, these flowers develop into bright red berries about the size of a pea, arranged in loose clusters. The berries persist through winter and are eaten by birds, which disperse seeds across the landscape. If you see a shrub with this combination—feathery compound leaves, woody stems, and persistent red berries—you likely have nandina.

Nandina can be confused with young bamboo or with native plants like elderberry or viburnum, so look for the distinctive feathery leaf pattern and the way the berries cluster. If you are uncertain, photograph the plant and contact your local Clemson University Cooperative Extension office, which can confirm the identification.

Why Nandina Spreads and Where It Takes Hold

Nandina spreads primarily through bird-dispersed seeds. Birds eat the red berries and deposit seeds across the landscape in their droppings, often in disturbed areas, along fence lines, and in open woodlands. The plant also spreads through underground rhizomes—horizontal root stems that send up new shoots—making it difficult to eradicate once established. A single mature plant can produce hundreds of berries in a season, and seeds can remain viable in the soil for years.

The plant thrives in South Carolina's climate and soil conditions and is particularly aggressive in areas that have been cleared, burned, or otherwise disturbed. It tolerates both sun and shade, though it grows most vigorously in partial sun. Once nandina establishes in a natural area, it forms dense thickets that shade out native understory plants, reduce food sources for wildlife, and alter the structure of the forest floor.

Removal Methods for Small and Large Infestations

For small infestations—a few scattered plants—hand removal is often effective. Dig out the entire root system, including the rhizomes, which extend horizontally underground. This works best in loose, moist soil. Wear gloves and dispose of the entire plant in a sealed bag or burn pile; do not compost it, as seeds and rhizome fragments can survive composting and spread the plant elsewhere.

For larger plants or established patches, cutting alone is not enough. Cut all stems as close to the ground as possible, then immediately paint the fresh cut surface with a brush or sponge soaked in a herbicide containing glyphosate (such as Roundup) or triclopyr (such as Garlon). Follow the product label for dilution and safety precautions. The herbicide moves through the cut stem into the root system and kills it. Repeat cutting and treatment if new shoots emerge from the roots.

For extensive infestations, repeated cutting over two to three growing seasons can exhaust the root system, though this requires persistence. Each time new shoots appear, cut them as soon as they emerge. This prevents the plant from photosynthesizing and rebuilding root reserves. Some landowners hire professional vegetation management contractors who have access to heavier equipment and more potent herbicides approved for larger-scale work.

Herbicide Options and Application Safety

Glyphosate (the active ingredient in Roundup and generic versions) is effective on nandina when applied to fresh cut surfaces. It is a non-selective herbicide, meaning it kills most plants it contacts, so apply it carefully and only to nandina stems. Triclopyr (Garlon) is another option and is sometimes preferred for woody plants because it is absorbed through foliage as well as cut surfaces. Both are available at garden centers and farm supply stores in South Carolina.

Always read and follow the product label completely before use. Wear gloves, eye protection, and long sleeves when handling herbicides. Do not apply herbicides near water sources, and be aware that drift can damage nearby plants you want to keep. If you are uncertain about herbicide use or if the infestation is large or near sensitive areas, contact a licensed pesticide applicator or your local Clemson Cooperative Extension office for guidance.

Some landowners prefer to avoid herbicides altogether and rely on repeated cutting, though this takes longer. On small properties or in areas where chemical use is restricted, this manual approach is a reasonable alternative if you are willing to commit to several seasons of follow-up work.

Preventing Nandina from Spreading on Your Property

The most effective prevention is to avoid planting nandina in the first place. If you have an established nandina in your landscape, consider removing it or managing it closely to prevent berries from maturing and spreading. Deadheading—removing flower clusters before they develop into berries—stops seed production but requires annual attention and does not address the plant's invasive root system.

Monitor your property regularly for volunteer nandina seedlings, especially in disturbed areas, along fence lines, and in open woodlands. Remove seedlings by hand-pulling or digging while they are small and before they establish a deep root system. Early removal is far easier than dealing with mature plants.

If you live near natural areas or conservation land, removing nandina from your property helps protect those areas from invasion. Talk with your neighbors about the problem; coordinated removal across multiple properties is more effective than isolated efforts.

When to Contact Professionals and Local Resources

For large infestations, steep terrain, or areas near water or sensitive habitats, professional removal is often the best choice. Licensed vegetation management contractors in South Carolina have equipment, expertise, and access to herbicides that may not be available to homeowners. They can also dispose of plant material properly and follow up to ensure regrowth is controlled.

Your local Clemson University Cooperative Extension office offers free or low-cost advice on nandina identification, removal methods, and prevention. Extension agents can also connect you with local contractors or conservation organizations working on invasive species management. The South Carolina Department of Natural Resources maintains information about invasive species and may have resources or programs related to nandina control in your area.

Frequently Asked Questions

Is nandina illegal to own in South Carolina?

Nandina is prohibited for sale in South Carolina, but existing plants on private property are not subject to removal orders. However, it is considered a prohibited invasive species, and many conservation organizations encourage removal to prevent spread into natural areas.

Can I burn nandina stems and branches?

Yes, burning is an effective disposal method if you have a safe place to do so and comply with local burn regulations. Check with your local fire department or county extension office about burn bans and permit requirements in your area before burning plant material.

How long does it take to kill nandina with herbicide?

Herbicide typically kills the root system within two to four weeks of application to a fresh cut surface, though visible above-ground death may take longer. New shoots may still emerge from the roots if the herbicide did not reach all of the root system, so monitor the site and retreat as needed.

Will nandina come back if I just cut it down?

Yes. Cutting alone stimulates the plant to send up new shoots from the roots and rhizomes. Cutting must be combined with herbicide treatment or repeated over multiple seasons to be effective.

What native plants can I plant instead of nandina?

Native alternatives include American holly, inkberry, winterberry, and native viburnums—all of which provide fall color, winter berries for wildlife, and year-round structure without the invasive spread. Your local Clemson Extension office or a native plant nursery can recommend species suited to your specific site conditions.
