Noble flowers: The four noble plants of the ancient Chinese were the Chrysanthemum, the Orchid, the bamboo, and the plum, and therefore only the upper class Chinese were permitted to grow them in their gardens.

Orchids are popular: The orchid is the most popular houseplant probably because it is more easily available than in the past and it is very easy to care for.
