Plants that thrive in Charlotte, NC
Charlotte landscapes work best on Piedmont natives that accept acidic red clay, humid summers, and a zone 8a winter. Oakleaf hydrangea, inkberry holly, Virginia sweetspire, dwarf fothergilla, muhly grass, little bluestem, Christmas fern, Carolina jessamine, and Eastern redbud are the dependable core. The failure mode here is rarely heat or cold, it is a plant sitting in a hole dug into compacted clay that holds water for days after rain.
Charlotte growing conditions at a glance
- USDA hardiness zone
- 8a
- Region
- the Carolina Piedmont
- Rainfall
- about 43 inches a year, fairly evenly spread
- Soil
- acidic red Piedmont clay, usually compacted and stripped of topsoil on newer lots
- Hardest condition to design around
- compacted construction clay. On most Charlotte subdivisions the topsoil was scraped off, so the first design problem is soil structure rather than climate
Shrubs and small trees
Structure that establishes in red clay without heavy amendment, and does not need a spray program.
Eastern Redbud
Cercis canadensis
- Sun
- Full sun to part shade
- Water
- Moderate
- Mature size
- 20 to 30 ft
Caveat: Native, early flowering, and relatively short lived at 25 to 30 years. It also does not like having its roots disturbed, so plant it young and leave it alone.
Oakleaf Hydrangea
Hydrangea quercifolia
- Sun
- Part shade, morning sun
- Water
- Moderate
- Mature size
- 6 to 8 ft, dwarf forms 3 to 4 ft
Caveat: The straight species outgrows most foundation beds, so use 'Ruby Slippers' or 'Munchkin' close to the house. It flowers on old wood, so a spring pruning removes the blooms.
Inkberry Holly
Ilex glabra
- Sun
- Part shade to full sun
- Water
- Moderate, tolerates wet
- Mature size
- 3 to 5 ft
Caveat: The native evergreen substitute for boxwood, which matters in a region where boxwood blight is now established. Older inkberry goes leggy and bare at the base, so choose a dense cultivar and renewal-prune it.
Dwarf Fothergilla
Fothergilla gardenii
- Sun
- Part shade to full sun
- Water
- Moderate
- Mature size
- 2 to 3 ft
Caveat: Bottlebrush spring flowers and excellent fall color in a genuinely small package. It is slow, and it will not tolerate a dry, root-competitive spot under a shallow-rooted maple.
Grasses and ferns
Texture that survives both a wet Piedmont spring and a dry August.
Muhly Grass
Muhlenbergia capillaris
- Sun
- Full sun
- Water
- Low to moderate
- Mature size
- 2 to 3 ft, taller in fall bloom
Caveat: The pink fall cloud only happens in full sun. It is also late to green up, so do not replace it in April thinking it died.
Little Bluestem
Schizachyrium scoparium
- Sun
- Full sun
- Water
- Low
- Mature size
- 2 to 3 ft
Caveat: Great copper winter color, and the wild form falls over in rich or irrigated clay. Use an upright cultivar and keep it out of the lawn irrigation pattern.
Christmas Fern
Polystichum acrostichoides
- Sun
- Part to full shade
- Water
- Moderate
- Mature size
- 1 to 2 ft
Caveat: Evergreen and deer resistant, and it clumps rather than spreading. Plant in drifts on 18 inch centers if you want it to read as a groundcover.
Perennials and vines
Color and vertical interest without an invasive habit.
Carolina Jessamine
Gelsemium sempervirens
- Sun
- Full sun to part shade
- Water
- Low to moderate
- Mature size
- 10 to 20 ft vine
Caveat: The North Carolina state flower and a reliable evergreen vine, and every part of it is toxic if eaten. Keep it off fences that border a play area or a pasture.
Purple Coneflower
Echinacea purpurea
- Sun
- Full sun
- Water
- Low to moderate
- Mature size
- 2 to 3 ft
Caveat: The plain purple species persists for years in the Piedmont; the novelty-colored cultivars often do not survive a second winter in clay.
Threadleaf Bluestar
Amsonia hubrichtii
- Sun
- Full sun to part shade
- Water
- Low to moderate
- Mature size
- 2 to 3 ft tall and wide
Caveat: Gold fall color that rivals a shrub, and it takes about three years to fill in. In too much shade it leans and opens up.
What should you not plant in Charlotte?
Skip Chinese privet, nandina, English ivy, autumn olive, and Bradford pear, all invasive in the Carolinas. Also reconsider Leyland cypress for screening; it is planted in nearly every Charlotte subdivision and dies out in patches from canker and bagworm once it reaches full size.
What are the watering rules in Charlotte?
Charlotte Water does not run routine day-of-week watering restrictions, but tightens them in drought stages, and Charlotte's tree ordinance protects existing canopy on many lots. Check tree protection requirements before regrading or trenching irrigation near a mature tree.
Water rules and rebate programs change. Confirm the current stage and schedule with your local water provider before relying on it.
Questions
What plants grow best in Charlotte's red clay?
Carolina Piedmont natives handle acidic red clay without amendment: oakleaf hydrangea, inkberry holly, Virginia sweetspire, dwarf fothergilla, Eastern redbud, little bluestem, muhly grass, Christmas fern, Amsonia, and purple coneflower. The important technique is to loosen a wide area rather than digging a small hole and backfilling with rich soil, which traps water around the roots.
What should I plant instead of Leyland cypress in Charlotte?
Leyland cypress fails in patches from canker and bagworm once it matures, and a single-species hedge means one disease takes the whole screen. A mixed screen of inkberry holly, wax myrtle, and a native holly such as 'Nellie Stevens' gives the same privacy with far less risk of losing the entire planting at once.
Is Charlotte a good climate for hydrangeas?
Yes, with the right species. Oakleaf hydrangea is native to the Southeast and handles Piedmont clay and humidity well. Bigleaf hydrangea also grows here but scorches in afternoon sun and needs consistent moisture, so give it morning sun and shade after noon.
What invasive plants are a problem in Charlotte yards?
Chinese privet, nandina, English ivy, autumn olive, and Bradford pear are the main offenders in the Carolina Piedmont. All are still sold or already established in older landscapes, and privet and ivy in particular spread from residential yards into nearby woodland.
