Cultural significance and symbolism

In Chinese culture, the azalea is known as "thinking of home bush" (sixiang shu), and is immortalized in the poetry of Du Fu.

The azalea is also one of the symbols of the city of São Paulo, Brazil.

Azaleas and rhododendrons were once so infamous for their toxicity that to receive a bouquet of their flowers in a black vase was a well-known death threat.
