Rubus ursinus x ideaus 'Thornless'
Pronunciation: ROO-bus ur-SEE-nus eye-DAY-us
SKU #06991
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.

WATER: Water when top 2 inches of soil is dry.
SIZE: Quickly reaches 5 to 6 ft. tall and wide.

| Companion Plants | Salvia (Salvia); Rosemary (Rosmarinus); Yarrow (Achillea); Russian Sage (Perovskia); Lavender (Lavandula) |
| Care Instructions | 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 | The genus Rubus includes many different plants collectively known as "brambles" because they share viney growth and wickedly sharp thorns. This species is native to California and Oregon, named from the Latin for bear, the local wildlife that fed most heavily on the fruit. This nearly thornless form was developed in California from the 1923 cultivar, 'Boysen'. |
| Lore | The name blackberry is a misnomer because this isn't a true berry. It's a drupe, an entirely different sort of fruit. |
