A:  Hi Fiona! There's definitely a noticeable difference between grafted and own-root Koko Loko roses, and in my experience, grafted plants perform much better. Four seasons ago, I added both types to my bare-root rose collection (I now only offer grafted), and about seven years ago, I set up a trial section in my field to compare their performance side by side. Today, the grafted Koko Loko roses consistently outshine the own-root ones in my commercial cut flower production field, producing nearly twice as many blooms throughout the growing season. The grafted plants are also hardier and more vigorous overall.
