Flemish Perennial Association, VVPV vzw, is an association of and for lovers of perennials (and more generally: of gardens and gardening), founded in 1992.
It currently has approximately 1500 members, spread throughout Flanders, including a hundred members from neighboring countries, mainly Dutch. The aim of the association is to introduce as many people as possible to the possibilities of perennials in the garden.
This is of course not only about edible perennials, but with their membership card you get a discount on many places. That’s always a good thing.
