The ISHS is the world's leading independent organization of horticulturists acting as a globally recognized and sought-after platform for research, science-based information exchange and collaboration in support of sustainable innovation in horticulture.
Membership is open to all interested researchers, educators, students and horticultural industry professionals.
The International Society for Horticultural Science - in short ISHS – is a truly global network comprising over 70,000 individuals, universities, governments, institutions, libraries and commercial companies, thousands of whom joined as Individual Members, in addition to a substantial number of Institutional Members and some 50 Country/Region Members. ISHS is a major source of up-to-date information on global horticultural research.
ISHS aims to promote research in all branches of horticulture. It encourages the development of international co-operation, bringing together scientific and technical professionals to stimulate, facilitate and co-ordinate research and scientific activities on a global scale.

To nurture and deploy scientific growing knowledge for creating a better world The Council, which meets annually, is made up of delegates representing the interests of countries/regions, which have contributed a membership fee. Directors are elected by Council at the International Horticultural Congress which is held every fourth year. The Society's policies are guided by the Board of Directors.
In addition to the Council, an Executive Committee manages the scientific program. It is composed of the Chairs of the Divisions. It is via these bodies that ISHS communicates with members who have specific research interests covering the full range of horticultural science.
Divisions establish Working Groups that focus on specialized subject areas. Working Groups have an elected Chair and membership comprised of eminent horticulturists/horticultural scientists. Currently there are around 100 such Working Groups and others are formed when a need is identified.
The success of the ISHS, in relation to its effective communication and leadership of international co-operation, is largely through the 30+ specialized symposia held annually. These are organised locally in a country, each with a convener, an organising committee, a scientific committee and an editorial board. Designed to be self-financing, these symposia normally concentrate on a technical subject – a crop or research area. Invited speakers present papers, research findings are debated, discussions held, visits arranged and the editor compiles a monograph published as a volume of Acta Horticulturae. Acta Horticulturae is available to all registered participants attending symposia. Acta Horticulturae is archived in many academic/research libraries. The entire Acta Horticulturae library is available online and services the needs of thousands of researchers worldwide who use the www.actahort.org site.
The European Journal of Horticultural Science (eJHS) is the official journal of the ISHS. eJHS is an open access journal publishing significant plant science discoveries and new or modified methodologies and technologies with a broad international and cross-disciplinary interest in the scope of global horticulture. The journal scope covers both applied and fundamental aspects of the entire food value chain, including breeding, production, processing, trading and retailing of horticultural crops and commodities grown in temperate, Mediterranean, tropical and subtropical climates. Additional information can be found at www.ishs.org/ejhs
The other avenue for regular communication is Chronica Horticulturae, the quarterly publication of ISHS. In addition to containing a calendar of events, announcements, news items and details of forthcoming events, Chronica reports on the activities of Divisions and Working Groups, and publishes horticultural articles of interest to a broad audience.
A major benefit of ISHS membership is the privilege of attending the International Horticultural Congress every four years at discounted rates. Congresses are attended by 3,000 or more delegates. They are carefully planned over many years to address all areas of horticultural science of interest to members.
The Congress provides opportunities for individuals to present posters or make oral presentations of their current research work. Thus, information is shared with a wide audience.
There are numerous social gatherings, sight-seeing opportunities, and the chance to see local horticultural industries during specialized field trips.

All abstracts and manuscripts must be submitted through the following ROSA(Responsive Online System for Acta Horticulturae submission and review) link

ROSA user manual for authors
Acta Horticulturae guidelines:https://www.ishs.org/authors
- Only abstracts submitted in English will be reviewed.
- Abstracts must not exceed 300 words.
- Abstracts must not contain tables, pictures or graphs.
- All abbreviations must be spelled out on first use.
- Abstracts should be thoroughly checked for spelling and grammar.
- An abstract submission charge is due upon submission of an abstract and applies to the presenting author only. For ISHS Individual members, the abstract submission charge is fully waived. Those who do not hold a user account with ISHS yet: create an ISHS user account first at https://www.actahort.org/members/newmember?asc=1 . After payment and activation of your user account, you can start your abstract submission.
- Abstracts must always be submitted by the presenting author, using their own personal ISHS user account. Submitting an abstract on behalf of, or using the ISHS user account of another author is strictly prohibited.
- Abstracts must be submitted by 15 November 2026 for consideration by the Scientific Committee. Authors will be notified of provisional acceptance of abstracts by 31 January 2027 and will also be notified if the abstract has been selected for an oral or poster presentation.
- All oral presenters, including invited and keynote speakers, must submit a manuscript for Acta Horticulturae according to the Acta Horticulturae guidelines (https://www.ishs.org/authors) by 04 April 2027. (Alternatively, presenters have the option to submit a full scientific manuscript on the topic presented at the symposium, for publication in the ISHS Scientific Journal eJHS in lieu of submitting a manuscript for Acta Horticulturae. Papers submitted in this manner will go through the standard procedures for peer-reviewed journal papers.) Oral presenters who fail to submit a manuscript for publication in Acta Horticulturae or the ISHS Scientific Journal may be refused the floor for making their oral presentation. Authors of posters are strongly encouraged to prepare and submit a manuscript for Acta Horticulturae.
- Presenting authors of abstracts accepted for presentation (both oral/poster) must register for the symposium by 25 February 2027. Failing to register for the symposium will result in your abstract being withdrawn from the symposium program and your manuscript being withdrawn from the Acta Horticulturae symposium proceedings.
- Failing to present (oral/poster) at the symposium will result in your manuscript being withdrawn from the Acta Horticulturae symposium proceedings.

ISHS Young Minds Awards

During each ISHS Symposium two ISHS Young Minds Awards for junior scientists will be given:
- one award for the best oral presentation given by a junior scientist who is at the same time the presenter and first author of the submitted manuscript
- one award for the best poster presented by a junior scientist who is first author of the work
