This sterile barberry is not invasive!

Finally - a colorful, care-free barberry that won't make a nuisance of itself: Sunjoy Mini Maroon^®. It took Dr. Tom Ranney over ten years to develop, but the results were worth it. Sunjoy Mini Maroon barberry offers sumptuously deep purple-red foliage on a dense, nicely shaped mound. It needs no pruning to stay small and lush, and like all barberry, it is highly resistant to damage from deer and rabbits. And it does it all without producing the seeds which have made other varieties so problematic

- Deep purple-red foliage from spring through frost
