Welcome to Passiflora Society International (PSI)

Our Mission

PSI is dedicated to the conservation of the genus Passiflora through

  • the sharing of knowledge of the genus, its species and cultivars throughout the world
  • the promotion of cultivation and propagation of living collections
  • encouraging the creation and registration of cultivars for their flowers, fruit and other characteristics
  • seeking ways to ensure the survival of endangered species and cultivars.

Our Activities

Our activities and services include:


New members are always welcome. Choose from two levels:


PSI is run by an elected Management Committee elected by premium members and chosen from them, with Officers appointed by the committee.

Volunteers are always welcome, especially with specific expertise – cultivation, taxonomy, plants, IT, publishing – tell us how you can help!
