Pick-your-own blackberry fields stake the canes, so that the berries are easier to pick by the bucketful, and the berry are kept fresh and clean. The ruby red berry of the Black Satin Blackberry ripens to a beautiful black color. The Black Satin blackberry was discovered as a thornless mutation in an Illinois field, and the Black Satin bushes are among the most cold hardy blackberry cultivars for commercial production.The flavor and aroma of fresh Black Satin blackberries are excellent, and Nursery grown mature plants can bear fruit the first year planted.
