BLACKBERRY Rubus Allegheniensis
Rubus allegheniensis, or common blackberry, is very common in eastern and central North America. It is also naturalized in a few locations in California and British Columbia.
Characteristics can be highly variable, typically 5 feet (150 cm) but occasionally rarely over 8 feet (240 cm) high, with single shrubs approaching 8 feet or more in breadth, although it usually forms dense thickets of many plants.

Germination: Pour boiling water over the seeds, and let sit for 24 hours. Then sow just under the surface of the soil, and place the container in the fridge for 90 days.
