The International Association of Horticultural Producers (AIPH / IAHP) is an international organisation dedicated to promoting horticultural producers and held the international garden / flora festivals or expositions worldwide.


The organisation was formed in 1948 in Switzerland for the international marketing purposes and now supports breeders' rights, the environment and international exhibitions.

International festivals have been recognised by the AIPH since 1960 at a Floriade in Rotterdam.[1]


At least 4 events were held including the 1999 World Horticultural Exposition in Kunming, China and Expo '90 in Osaka, Japan.[1]


15 events were held in the 2000s including Floriade 2002 in Haarlemmermeer, Netherlands and an exhibition in Shenyang, China in 2006


Taipei 2010/2011[edit]

The 2010 Taipei International Gardening and Horticulture Exposition was held in Taiwan from November 6, 2010 to April 25, 2011 hosted by the Taipei City Government and the Taiwan Floriculture Development Association (TFDA). This event offered an opportunity to inspire people’s concern for their living environment around the world, and aimed to stir them to make their homes, neighborhoods and communities more green, more energy efficient, and sustainable. This was an A2/B1 classification event[2]

Venlo 2012[edit]

In 2012 the Floriade 2012 was held in Venlo. As with other Floriades this was an A1 classification event.[2]

Grade of AIPH Exposition[edit]

  • A1: International exhibition of long duration (at least 3 months, 6 months at most)
  • A2: International exhibition of short duration (at least 8 days, 20 days at most)
  • B1: National exhibition of long duration (including foreign participations, if so desired)
