Royal Queen Seeds is a breeder rather than a reseller: every strain on their site is their own, which is why the same plants turn up in half the shops in this index under their name. 164 of the 169 products read here are strains another shop already sells, so their prices land as a comparison rather than as new pages.
They put the emphasis on discretion and delivery: seeds leave a warehouse in Spain, they deliver only to private addresses, and they refuse responsibility for parcels sent to post boxes, pack stations or forwarding companies. Track and trace follows once the parcel is on its way, though they warn that nothing updates until it reaches the destination country.
Their site claims 4.7 out of 5 over more than sixty thousand reviews and a 99 percent germination rate. Those are their own figures about themselves and are not checked here.
