About ISHS

The world's leading independent organization of horticultural scientists


The International Society for Horticultural Science - in short ISHS – is a truly global network comprising over 60,000 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 Member Countries/Regions. It 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.

Joining ISHS

If you have not joined, now is your opportunity! More details on ISHS membership, including an online application form at www.ishs.org/members

ISHS Young Minds Award

During each ISHS Symposium two Young Mind Awards for junior scientists will be given:

one award for the best oral presentation given by a junior scientist who is in 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


We are not planning a formal pre or post tour but there is a great opportunity to combine the Symposium with the IFTA Summer Study Tour.
This and the Symposium are two separated events, but we worked with the International Fruit Tree Association to organize them consecutively so people can conveniently attend both.

IFTA Summer Study Tour

The program is not defined yet but the tour will cover the South of Washington State, while the field day of the Symposium will visit the central part of the State.

Travel Information

Below you can find some useful tips on how to reach Wenatchee and other information regarding entering the United States


Only Alaska Airline serves the Wenatchee Pangborn Memorial Airport (EAT), with three direct flights (~30min) per day to and from Seattle Sea-Tac Airport (SEA).

Buy bus

Wenatchee Valley Shuttle provides passengers van transportation from the Wenatchee train station, close to downtown, to Sea-Tac Airport. They have three roughly 3hours trips daily in a comfortable van provided with Wi-Fi internet connection.


The airport is 25-30 minutes away from Wenatchee downtown. As the hotels don’t provide shuttle service, you might want to book a taxi ride (~30US$). Taxi late in the evening need to be reserved in advance. Not all taxi service will accept card payments.
Ridesharing services such as Uber and Lyft are now an option in town too.

Travelling to the USA

A foreign national traveling to the United States to conduct temporary business, such as attending or speaking at a conference, needs a visitor visa (B-1), unless qualifying for entry under the Visa Waiver Program.
Citizens of Canada traveling to the United States generally do not require a nonimmigrant visa, except for the travel purposes described here.

The Visa Waiver Program (VWP) permits most citizens of 38 countries to travel to the United States for business or tourism for stays of up to 90 days without a visa. Travel to the US under the VWP requires Electronic System for Travel Authorization (ESTA) approval.
Upon completion of an ESTA application, a traveler is notified of his or her eligibility to travel to the United States under the VWP. See additional information.

For those visitors who will need to get a visitor visa, visa appointment wait times can vary significantly from country to country.
