Growers, breeders, technical advisors and marketers are represented by the International Protea Association (IPA) and researchers and educators by the International Protea Working Group (IPWG). The IPWG is a specialised group of the Ornamentals Section of the International Society of Horticultural Scientists (ISHS). Since this first joint meeting communication between growers and researchers has continued, with the publication of 8 Acta Horticulturae reporting proceedings of IPWG symposia.
