PLEASE be sure you are a Member of the PSI on the website if you wish to participate in the sale: www.passiflorasociety.org/join/

** The Fall 2012 Newsletter will be sent to the printers next week. If you are a Premium Member, expect it in your mailbox in May! We may be still playing “catch-up”, but the Spring 2013 newsletter is nearly complete as well, and should be shipping this summer, as well as our Fall issue getting close to completion.

** We have a new hybrid/cultivar Registrar.  Please help me welcome Shawn Mattison to the team!  He is diligently learning the regulations and stipulations so that every current and future registration put through the PSI is done so with the utmost confidence that proper nomenclature and ICRA/ISHS allowances are followed for all posterity. Besides all that, he’s a nice guy to work with. If all goes as planned, we will begin to accept new hybrid registrations in June or July.
