Boysenberry Floricane ( Blackberry/Raspberry Hybrid) Thorny 12 cm Zones 4-9
Boysenberry Floricane Thorny (Rubus ursinus x idaeus) is actually a hybrid of several species of blackberry (Rubus fruticosus). Boysenberry is named after the person who popularized the plant, Rudolf Boysen, a Swedish berry breeder who lived in California in the 1920s. The Thorny, Trailing canes of what came to be called "boysenberries" are thought to have descended from a cross between the Loganberry (Rubus x loganobaccus) and Dewberry (Rubus ursinus). Black, large, delicious, sweet fruit is very attractive and popular. Boysenberries grow best in moist soil enriched with plenty of decomposed organic matter, and they perform best during a long, temperate growing season. Boysenberries have thin, trailing runners that must be trained to an upright support structure or they creep along the ground and form impenetrable thickets. They bear fruits about July on 1-year-old FLORICANE canes that afterward need to be cut to the ground. After pruned, each plant should have eight to 12 newly sprouted canes, each cut back to 6 to 8 feet long and left to mature for next year’s crop of berries. Zones 4-9 12 cm pot.
