The message on the rooting hormone applies to trademarked plants. For example, if you buy 'Wave' petunias those are trademarked by the company. In fact, Wave is the brand name just like Kraft is the brand name of many food products. You can sell petunias that spread like that, but you cannot call them 'wave petunias'. Think of it like the labels you see on generic or store brand products; compare to 'name brand'.
