The International Plant Propagators’ Society (IPPS) is an international association of plant production professionals. The Society provides a forum for sharing plant production knowledge with the aim to improve the professionalism, knowledge and skills of its members.

IPPS has since its inception in 1951 developed into the leading global plant production knowledge network. It has a worldwide membership of over 1600 members who have the opportunity to meet regularly on a regional and international level by attending educational conferences, tours, field days and workshops. The Society offers various scholarships, research grants and exchange programs.

A unique benefit IPPS members enjoy is access to the vast library of horticultural knowledge, the Combined Proceedings of annual IPPS conferences.


There are now 65 volumes of professionally edited papers and presentations available online. The Combined Proceedings are also available as a hardcover book.

IPPS membership is organized and administered on a regional level. These regions are currently spread over eight geographically defined areas: Australia, New Zealand, Japan, Europe, Southern Africa and in the USA: the Eastern Region, Western Region & Southern Region.

Are you a professional involved in ornamental plant production, horticultural research and education or any other allied field? Do you wish to learn more and are you willing to share your knowledge? Then join now, you would certainly benefit from IPPS and its members from you!
