Seven pounds of berries were picked from these two thornless blackberry plants in their third year, and the first year of production. The berries ripen over a period of time. Quality is excellent. All the berries have a slight tart taste. This depends on the degree of ripeness. If the berry is fully ripe, determined by it falling off the stem when touched, the berry will be sweet with almost no tart taste.
