What Are Plant Patents, Trademarks, and Brands?

Share the joy

A proliferation of plant patents, trademarks, and brands in recent years has turned plant shopping into a rather confusing experience. Plants now have goofy names. Have you noticed that the Knock Out rose is also called ‘Radrazz’? Or that Endless Summer hydrangea also answers to the name of ‘Bailmer’?
