Ternstroemia, often called Japanese Cleyera in the Southern US nursery trade, is a handsome evergreen shrub reaching 8-12 feet with whorled leathery dark green leaves that emerge bronze-red and turn burgundy in cool weather. Small fragrant creamy flowers in summer are followed by red berries. A tough, drought-tolerant, and pest-resistant evergreen widely used as a foundation shrub or hedge throughout the Southeast US.

History
Ternstroemia gymnanthera is native to southern Japan (Kyushu and the Ryukyu Islands), southern Korea, China, Taiwan, and much of Southeast Asia. English botanist Thomas Archibald Sprague formalized the current name. The genus Ternstroemia honors Swedish naturalist Christoffer Tärnström, an 18th-century student of Linnaeus.
In the North American southeastern landscape trade the species is sold as Cleyera japonica, though taxonomically the two species are distinct and belong to different families (Ternstroemia in Pentaphylacaceae, Cleyera in Pentaphylacaceae—though these and Theaceae affinities have been long debated). True C. japonica is rarely grown commercially in the US. Ternstroemia forms a dense rounded evergreen shrub or small tree to 3-5 meters with bronzy-red new growth turning dark glossy green at maturity, small fragrant cream flowers in early summer, and red berries in fall.
The species tolerates heat, humidity, and poor soils extremely well, explaining its popularity throughout the humid southeastern United States as a foundation shrub, hedge, and small tree. A longtime Southern US landscape staple for heat and humidity tolerance, now so ubiquitous around Southern homes that it has become a regional signature foundation shrub. Native from Japan and China, it adapted superbly to Gulf Coast conditions.
Symbolism & meaning
What It Symbolizes
Japanese Ternstroemia is steadfastness through the Southern year, holding its glossy color through brutal heat and humidity that defeats softer evergreens. Each winter it transforms, burgundy tones replacing summer green in a quiet seasonal metamorphosis. In its calm, unbroken presence lies a year-round backbone for gardens that ask shrubs to work hard.
- Steadfastness — year-round color in Southern heat
- Transformation — burgundy winter foliage contrasts with green summer
Where the Name Comes From
The name Japanese Ternstroemia points to Japan. Genus honors Swedish botanist Christopher Ternstroem; 'gymnanthera' means naked anthers.
