(paghat) expounded:
B. davidii is in the top-20 invasive pest-plants in England. It has never
been given such a high pest status in the USA, as it is believed to share
the environment rather than displace native species, a debatable premise.
There is no question but that it is long naturalized on both coasts.
It is only marginally hardy here, and I've never seen one reseed. But
that's just this area, I can't speak for others.
