It is an unusual practice that just doesn't seem proper, even if it is considered legal. So, if i understand this correctly...Black Diamond Crape Myrtles are actually the work of Dr Pounders at the USDA/ARS Thad Cochran center, but Berry Nursery can make a bunch of money by Trademarking a name and selling them for more?
Actually it is not unusual, it is very common. And you are correct about Berry Nursery making a bunch of money just by changing the name. And the fact that Berry Nursery owns a trademark doesn't matter. The names that they have applied to these Crape Myrtles is Best Red, Blush, Crimson Red, Pure White, and Red Hot.
