Bob Holzinger will open the Fall 2026 American Seedbank Sale to Premium Members on Friday, October 23rd, and then to Basic Members on Saturday, October 31st. Those who have donated seeds will be able to access the sale a few days earlier. Additional details, including a list of seeds that will be available on the sale, can be found on the preview page HERE.
Members living outside the United States are also welcome to order from this sale, but please understand that we are unable to guarantee delivery. To ensure seeds arrive in the best possible condition, Bob will box up all orders.
If you are a Basic Member and want to take advantage of this low price (instead of the standard $5), as well as priority access to the sale and other benefits, it is not too late to upgrade your membership.
Premium membership starts at just $20 per year, during which there will typically be 2 American and 2 European sales – so do the math! More details on the Renew / Upgrade page.
As previously announced, the AGM will be held in Palermo in the Sala Lanza in the Botanical Garden at 9.45 am on Friday 25th September and the presentations afterwards from 10.45 to 13:30. We believe now that we will have wifi laid on and that it should therefore be possible for Members who wish to do so to join the meeting remotely. If that applies to you please send a contact form stating your membership level so that we can inform you of the arrangements once we have worked them out.
Once you have logged in, the Agenda for the AGM will be found here.

We are pleased to announce that Yero Kuethe’s long-awaited monograph on the genus Passiflora is expected to be published in about 18 months’ time
It will be in full colour and contain some 1500 pages around A4 in size, in 2 hardback volumes.
As you know, this is the first monograph on Passiflora since Killip, whose work was published almost 100 years ago, had no illustrations and was restricted to American species.
In contrast, Yero’s work will have worldwide coverage and be fully illustrated. It will be indispensable to any Passiflora enthusiast.
To assist their pricing and planning generally, the publishers need an idea of how many individuals and others are likely to buy a copy.
To help answer this question, please could you let PSI know how likely YOU are to buy a copy by completing the simple form here, where you will also find more information about the monograph.
The form is just for guidance and won’t commit you.
Thanks to all who have registered, and apologies to any who have left it too late ! That said, cancellations occasionally happen, so do submit a contact form if you’d like to be put on the waiting list.
