Remains bushy even without pruning and will not grow taller than about 3 to 4 meters. The leaves are lancet-shaped, and rarely longer than 12 cm or broader than 3 cm. This plant is more suited to moderate climates; it is little frost resistant and has limited resistance against diseases.
  Die Camellia assamica
can grow into a sizeable tree of 8 to 15 metres in height (in rare cases even up to 25 or 30 meters). The leaves are oval and grow to a length of 15 to 25 cm at a width of around 10 cm.

The assamica is particularly suited to tropical climates with high air humidity.

They are the result of various crossbreeding of the two species. The aim was to develop a cultured species producing particularly high yield that is robust and of delicate taste. They form the basis of modern tea plantations and are continually improved.
