International Plant Propagators’ Society

  1. IPPS is an international association of plant production professionals, including those involved in horticultural research and education. 
  2. During 1951 a group of about 70 plant propagators met in Cleveland, Ohio, and formed the IPPS with the aim to share their knowledge. 
  3. Their motto ‘to seek and to share’ remains the core value guiding the Societies' activities. IPPS has since broadened into an international forum for sharing plant production knowledge and skills.
