What we do

IPPS Regions coordinate and organize various forums and activities where members can learn and share plant production knowledge.

Annual Conferences:

Regional Annual Conferences are the highlight on every IPPS members’ calendar. These annual meetings are usually combined with a pre- and post-conference tour, visiting nurseries and other places of horticultural interest.

Combined Proceedings:

The papers presented at the annual conferences are available to all IPPS members. Professionally edited papers and presentations can be accessed on the PROCEEDINGS page. There are currently 68 Combined Proceeding volumes available.

Field Days & Workshops:

IPPS Regions regularly organize field days, nursery visits and workshops throughout the year.

Scholarships & Exchange Programs:

Various scholarships and exchange programs exist to encourage young members to travel and learn from others. Please visit the STUDENT SCHOLARSHIPS pages for more information


IPPS was founded by Jim Wells in Cleveland in 1951, with 70 other propagators. Jim Wells was an Englishman with a nursery in NJ, who went against the culture of keeping propagation information, or trade secrets, to himself and his business. Jim believed that the only way to improve is by sharing and exchanging information, hence our motto: "To Seek and To Share." Wells not only founded the first IPPS Region, the Eastern Region of North America, but later helped organize the British-Irish region and spread the seeds for new international regions to be formed.

Today the IPPS is truly international — 8 regions around the world, 3 regions in US and over 2,200 members world-wide.

Who may become a member?

Membership is for individuals only. Any professionals in all fields of plant production, including horticultural research and education, students in horticulture, botanists and allied suppliers to the plant production industry, may apply for membership.

IPPS Membership is organized and administered on a Regional level. Each Region is a defined geographical area. The current Regions are: Australia, Europe, Eastern Region of North America, Southern Region of North America, Western Region of North America & Canada, Japan, New Zealand and Southern Africa.

Anyone not residing in any of the current geographical regions may apply for an International membership, administered by the IPPS International Office.
