For 75 years, the International Association of Horticultural Producers (AIPH) has brought together producers of flowers, ornamental plants, and trees. AIPH advocates for the importance of plants by promoting and protecting the interests of ornamental horticulture on a global scale. 

In addition to promoting ornamental horticulture, AIPH supports international grower associations, providing them with resources, education, and networking opportunities. These associations represent growers and breeders nationally, giving them a platform to voice their concerns and work towards common goals. The Canadian Nursery Landscape Association is a Full Member of AIPH. 

AIPH has the authority to approve International Horticultural Expos as part of the International Paris Convention, which is signed by governments worldwide. The International Horticultural Expo Movement has been around for over 60 years, with a focus on creating green spaces and educating and inspiring citizens with plants and flowers. These Horticultural Expos last up to six months and are the only mega events that bring nature closer to people.
