OVERVIEW
Description A prolific producer of sweet-tart, large, reddish black fruit in midsummer on second year growth. Small white flowers precede the fruit in spring. Unfortunately, despite it's given name, it is not truly thornless, but the size and number of thorns is less than the thorny variety. Thorny canes may emerge from the ground, depending on conditions. The fruit can be eaten fresh, cooked, or frozen. Deciduous.

Foliage Color Green
Companion Plants Salvia (Salvia); Rosemary (Rosmarinus); Yarrow (Achillea); Russian Sage (Perovskia); Lavender (Lavandula)
CARE
Care Provide fertile, mildly acidic, well-drained soil. In hot summer regions, shelter from harsh sun, and mulch to keep roots cool. Water deeply, regularly in first growing season to establish extensive root system. Feed in early spring. After harvest, remove canes that have fruited. Leave newer canes to produce next season's crop; train on a trellis.
HISTORY
Lore The name blackberry is a misnomer because this isn't a true berry. It's a drupe, an entirely different sort of fruit.
