The Black Satin Thornless Blackberry is superior to any other varieties we have seen. Hardy in the Midwest and south — even recommended for northern climate if you are careful to cover with a mulch to protect it during the winter. Thornless Blackberries are extremely vigorous and disease free. Plants will not sucker. Consistently produce a heavy crop. You’ll pick 35-40 berries on each thornless stem! Berries are large, attractive and have a luscious flavor. Ripen in early August.
