Highlights
Silky camellia (Stewartia malacodendron) has one of the most striking flowers of any native shrub. Each bloom is a white saucer about 3 inches across, with five crimped petals around a burst of 50-100 purple stamens with blue anthers. The Forest Service calls it one of the most beautiful native species of the south, and it’s hard to argue.
It’s also rare, slow and fussy, which is why so few people have seen one. This is a plant for a patient gardener in the coastal South with a shady, woodsy spot. If that’s you, it’s worth the hunt.
Is silky camellia a good choice for my yard?
Yes, if…
- You garden in the coastal South. It grows wild on the southeastern coastal plain, and NC State rates it for zones 7b to 9a.
- You have morning sun and afternoon shade. It thrives on early morning sun and wants shade in the heat of the day.
- Your soil is rich, moist and drains well. Think of the edge of a hardwood woods, under tall trees.
- You like a plant with a story. Very few of your neighbors will have one.
Skip it if…
- You want fast results. It’s slow growing, and young plants can take years to bloom.
- You might move it later. The roots strongly resent disturbance, and established plants rarely survive a transplant.
- You garden in the mountains or the North. Look at its cousin, mountain stewartia, which grows in the southern Appalachian Mountains and Piedmont and is hardy to zone 5.
- You need a sure thing. Even experts lose them. Plant it because you love it, not because you need a hedge.
Why silky camellia matters
In the wild, silky camellia is uncommon and shrinking. Florida lists it as state endangered. In Georgia it’s ranked S2, imperiled, with about 40 populations on record but only 9 confirmed since 2000. Alabama ranks it S2S3 and North Carolina S3. Arnoldia reports it’s imperiled by habitat destruction, mostly logging and building.
A garden plant from a nursery won’t save a wild population, but it does keep the plant in circulation and in people’s minds. Never dig one from the wild. The Alabama Plant Atlas asks gardeners to buy from nurseries that specialize in natives instead.
The flowers feed pollinators too. NC State notes they attract bees and butterflies that come to collect pollen.
Where silky camellia shines in your yard
- A woodland edge under tall oaks or pines, where the light is dappled.
- Beside a path, where people can see the flowers up close.
- A shady courtyard on the east side of the house.
- A specimen plant in a native woodland garden, with ferns below.
Beginner tip
Buy the biggest plant you can afford from a nursery that grows its own from seed. A small seedling can take many years to flower, and a bigger plant gets you there sooner.
How to grow silky camellia
Where to plant
Pick the spot carefully, because you only get one try. Morning sun and bright afternoon shade is ideal; in deep shade it flowers infrequently. Give it rich, moist, well-drained soil with plenty of leaf litter. It prefers acidic soil, though North Carolina has wild plants growing over high pH soils such as marl.
Size
Most plants stay 10 to 15 feet tall, and the Lady Bird Johnson Wildflower Center says it can reach up to about 20 feet, often much shorter. NC State gives a spread of 15 to 25 feet over many years, often as a multi-stemmed shrub.
Water and care
Keep it evenly moist through the first two summers, with a layer of shredded leaves over the roots. After that, water in long dry spells. It does not respond well to pruning, so don’t shape it. Just remove dead wood.
When it blooms
Flowers open from late spring into early summer, April to June depending on where you live. In fall the leaves turn greenish-yellow to yellow.

The trickChoose its spot once: the roots hate to be moved.
Where is silky camellia native?
Native to 11 US states
Sources: NatureServe, Royal Botanic Gardens, Kew (World Checklist of Vascular Plants) and the USDA PLANTS Database, compiled by The Plant Native. How we map native ranges
It’s one of two stewartias native to North America. Its range runs across the Gulf and Atlantic coastal plain, from Virginia to Texas, at low elevations.
Pick the spot carefully, because you only get one try.
What are good pairings for silky camellia?
Pair it with other woodland natives of the Southeast that like moist, rich soil: sweetbay magnolia, Carolina silverbell, Virginia sweetspire, oakleaf hydrangea and, underneath, Christmas fern. Its tea-family relative Franklin tree is another rare beauty for the collector.
Where can I buy silky camellia?
Look for specialty native nurseries in the Southeast, native plant society sales, and arboretum plant sales. Supply is small and sells out, so get on a waitlist if you can. Make sure the plant was nursery-propagated, never dug from the wild. Start with our list of native plant nurseries or order online.
FAQs
Is silky camellia a real camellia?
No, but it’s a cousin. It’s in the tea family with true camellias, which is why the Forest Service says its flower reminds people of the Japanese Camellia. Unlike camellias, it loses its leaves in winter.
Why is silky camellia so hard to find?
It’s slow to grow, hard to start from seed and hates being moved. The Alabama Plant Atlas calls it slow growing, difficult to transplant, and a seed company notes sporadic germination over two or three years. Expect to search, and to pay more than you would for a common shrub.
What’s the difference between silky camellia and mountain stewartia?
Look at the center of the flower. Silky camellia has purple stamens with blue anthers. Mountain stewartia has orange anthers. Mountain stewartia also grows farther north and inland, in the mountains and Piedmont.
Is silky camellia endangered?
In parts of its range, yes. Florida lists it as state endangered, and Georgia ranks it imperiled. Across its whole range it’s uncommon, and Flora of North America calls it of conservation concern in some areas.
How long until silky camellia blooms?
It can take years. At Polly Hill Arboretum, a plant grown from seed first bloomed in 1989, 27 years after sowing. A nursery-grown plant a few feet tall should bloom much sooner.
Can silky camellia grow in full sun?
Not in the South. It wants deep shade during the heat of the day. Morning sun is plenty.
Plant nerd fact
Named by mistake
The genus honors John Stuart, the Earl of Bute. In the dedication, his name was misspelled “Stewart.” A botanist tried to fix it to “Stuartia” in 1785, but botanical rules require adherence to the original spelling, so the typo stuck. Every stewartia in every garden carries it.
Silky camellia is a plant for someone who likes a challenge and a quiet reward. Give it the right shade and soil once, leave it alone, and one June morning you’ll find those purple-centered flowers open on your own shrub. For another southern native with big white flowers, see our guide to native magnolias. Happy planting!
