Historical Facts

During the 19th. century, horticultural scientists realised that an exchange of their views and experience should be promoted internationally in order to globalise their national or even regional efforts. The first International Horticultural Congress was organised in 1864 in Brussels (Belgium) as a first step in realising this objective. With the organisation of this congress followed by he next event one year later in Amsterdam (Netherlands), the seeds of our actual International Society for Horticultural Science were planted. In 1923 the foundation of an International Commission for Horticultural Congresses was established.

The International Society for Horticultural Science was officially registered as such on April 27, 1959, formalising a global network of international horticultural co-operation. The creation within ISHS of Sections according to the various horticultural cultures, Commissions corresponding to the different branches of horticultural science and technologies extending across the different cultures and our Working Groups, is a guarantee for the high level of the international workshops, symposia and congresses that are organized each year in co-operation with ISHS.

In 2018 the Executive Committee re-organized the scientific structure creating Divisions instead of the previous Sections.
