Negative coriaceous On Feb 21, 2014, coriaceous from ROSLINDALE, MA wrote:

Trade, transport, and planting this shrub is illegal in my state and two others, because it invades and destroys natural areas. I've seen state woodland turned into impenetrable thorny thickets of this species, where nothing else in the understory layer survives. It has naturalized across North America north of a line running from Georgia to Wyoming, and also in Washington.
