Three different camellia species are most often grown: Camellia japonica, C. reticulata, and C. sasanqua. You may also find a fourth species, C. hiemalis, which is similar to and was once sold as a variety of C. sasanqua. Hybrids that combine desired characteristics of different species, such as abundant foliage and large flowers, are also gaining in popularity. And although it's not grown in gardens, another camellia, C. sinensis, is cultivated for its leaves, which are harvested for tea.
Camellia japonica is what most people think of when they think of a camellia. It's prized for its abundant, glossy foliage, its flowers ranging from 2 to 7 inches across in shades of white to pink to red, and its long bloom period. While it's considered a spring-blooming camellia, the earliest japonicas begin blooming in October, and the late-blooming ones finish blooming in May. Alba Plena was the first camellia introduced to the West from Asia in the 1700s, and it's still one of the most widely sold varieties.
The Camellia reticulata varieties are known for their large flowers, which may reach up to 9 inches across. The plants themselves tend to be open and rangy with dull green leaves. They look best underneath garden trees that provide light shade, and they don't like to be crowded. Though flowers are usually red or pink, you can also find blooms that are white or variegated. Popular reticulatas include Buddha and Shot Silk.
Camellia sasanqua and its close relative C. hiemalis are early bloomers. Some varieties begin flowering as early as September; the late bloomers are finished in January. Sasanquas make up for their relatively short blooming season by producing masses of flowers. They also can take more sun than other camellias. Among the most well-known sasanquas are Apple Blossom, Mine-No-Yuki, and Yuletide.
Flower color is the first priority when choosing a camellia, so buy when plants are in bloom in fall and winter. Also check the blooming period; with smart planning, you can have flowers from September through May. As always, look for a healthy plant with a good overall form.
