Botanical: Rubus fruticosus 'Triple Crown'
General Characteristics: 'Triple Crown' is a semi-erect, thornless blackberry cultivar. Good freezing quality. Suited for any grower. This is a self-fruitful, free-standing, thornless shrub that produces one crop of fruit per year. 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 and it not considered appropriate for ornamental use. Blackberries fruit on two-year old canes. After they have finished fruiting, the canes should be pruned away at the base. The fruit attracts birds. The brown thrasher, gray catbird, northern cardinal, northern mockingbird, and white-eyed vireo commonly nest in blackberry and raspberry thickets. Flowers attract butterflies, notably the western tiger swallowtail. Although the flowers are attractive, this blackberry is grown primarily as a fruit crop and is not considered appropriate for ornamental use.
