Many countries and regions from around the world, including the Democratic People's Republic of Korea, are attending the exposition whose theme is "Be part of theatre in nature, get closer to the quality of life".

The DPRK State Stamp Bureau issued new stamps to commemorate it.

A kind of stamp pictures tulips, with Korean and English letters "Floriade 2012 World Horticultural Expo" and the expo's emblem in its upper part.

Another three kinds of stamps depict roses of different colors.
