Have you been waiting to join PSI, but been frustrated by the “Suspended” notices on the joining and renewal/upgrade pages ? Then your wait is over ! They are back up and running. To make them more reliable, we have abolished the Join PSI Premium button altogether, and instead ask brand-new members to register first as Basic members and then upgrade to Premium if they wish.

To help avoid the unnecessary foreign exchange fees on both sides, we have added two additional currencies for payment – Euros and Pounds Sterling. We hope you will find this helpful.

A big thank you to the members who kindly acted as guinea-pigs during the testing period. If nonetheless you do encounter any difficulties, please use the contact form to let us know immediately. We are happy to receive compliments as well !

We hope you like the new website. The Passiflora you can see at the top of this page are newly registered cultivars. Apply now to register your new cultivar, and it will soon be here!

We are still in process of setting up the new site, having had to move it more quickly than expected, so bear with us.

If you have any comments or suggestions, please send them in – we’d be delighted to hear from you.
