An ISHS Symposium is an international scientific meeting sponsored by a Section, Commission or Working group in ISHS.
Each meeting can be supported by additional sections or commissions within ISHS, or co-sponsored in conjunction with industry groups or other scientific organizations outside of ISHS.
The proceedings of each ISHS symposium are published in a volume of the peer-reviewed series Acta Horticulturae (ISSN 0567-7572).
