Plant Breeders Rights PBR, what plants are covered?

Does anyone know whether there is a list or where I can get hold of a list of plants that are covered by PBR? I would have though that this information would be easy to find but I'm really struggling.

I recenty brought a plant from a nursery that was not a bred variety, but a species. I would have thought that species could not be covered by PBR, its not like any plant breeders have bred them.. Its seems that many plant labels state this but its not in fact true.

 

This is the organisation who you have to register new cultivars with http://www.ishs.org/sci/icra.htm I don't know much about plants breeders rights other than a species cannot be protected, now a species which has been grown on and propagated by an individual and then they select a particularly nice form then they can then register that as a cultivar

if that makes sense?

 

I have masses of surplus plants and want to sell them (to raise funds for more) but dont want to fall foul of PBR.

 

or if you are unsure then do not give a cultivar name at all just say they are genus species 'unknown cultivar' if your worried

 

I've often wondered about this as I have a Pulmonaria which said on the label when I bought it that it had PBR and could not be propagated. Has anyone ever tried stopping a Pulmonaria from propagating???? I have loads of Pulmonaria in my garden which have self seeded and crossed with each other, I have no idea whether the PBR one is now a parent but I'm sure it must be.

 

Thanks
