Note that our camellia plants are cultivars selected/bred by humans. Camellias have been cultivated by humans for centuries in China and Japan. Also note that while the tea plant (Camellia sinensis) is a camellia, not all camellias are used to make tea. They are very distinct as far as which is used to make tea, and there are different types of tea-making camellias and different parts of the plant are used to make various types of tea. Two of the camellia flowers are pictured below.
Camellia flowers are also a common subject of art in China and other Asian counties. What a rich connection the camellia has with humans!
