山茶花
One of the most important plants related to "Camellia japonica" is the "Camellia sinensis", which is the plant tea comes from. This plant is not usually grown in gardens because it has small white flowers, unlike the "Camellia japonica", which has larger, more beautiful flowers. It is not seen in art as often as the "Camellia japonica", but it is shown in a painting called the "Song Hundred Flowers" which hangs in the Palace Museum in Beijing. "Camellia sinensis" may have been used as medicine during the Shang Dynasty. It was first used for drinking during the Zhou Dynasty.
