Offering a germination guarantee while calling feminized seeds souvenirs looks like a contradiction, and newcomers often point it out. The explanation is that one shop serves many jurisdictions, so the guarantee speaks to buyers who may lawfully grow and the souvenir wording covers those who may not. Both elements appear at https://queenfeminizedseeds.com where the footer warns that sprouting seeds is illegal in many places even if owning them is not. It is awkward but honest, and the part that applies to you depends entirely on where you live.
