Full sun-part shade; regualer water. Grows to 3-5ft tall and wide. Named for its three crowning attributes: flavor - productivity – vigor. Self-fruitful, free-standing, semi-erect, thornless shrub that produces one crop of fruit per year. Fruits ripen to a juicy sweet flavor; over a 5-week period you can harvest and enjoy eating the large black beauties everyday for over 30 days. Clusters of white, 5-petaled, rose-like flowers in spring give way to firm, glossy blackberries of excellent eating quality that mature in summer. Although the flowers are attractive, this blackberry is grown primarily as a food crop. Good freezing quality. Flowers attract butterflies.
