Hong Kong's national flower is a Bauhinia Blakeana flower. The Hong Kong flag consists of a stylised, white, five-petal Bauhinia Blakeana flower sitting in the centre of a red background.
The red and white on the flag symbolises the 'one country two system' political alliance between Hong Kong and China, while the Bauhinia Blakeana flower, a flower native to Hong Kong, is a symbol of harmony.
