I chew the American Beautyberrys, the purple berries, as a fresh picked snack, but like wild black berries, there is a certain time, if too early they will be rather harsh & easily spit out. But if ya wait on them, they sometimes will ripen & taste just like a Sweetart candy. Now that isn’t always true tho,…some years they just don’t taste good no matter how long ya wait~~~just saying.
I have quite a few of the wild bushes around my place, they are easily transplanted, & some say: ‘they don’t mind being pruned hard, because they prefer to grow from new stems’. I transplanted this one a few years ago, I never did prune it & it is producing well this year also.
