Perhaps the issue is that the spanish bluebell is aggressive and could
probably satisfy the definition of invasive before too long. Foreign

grey squirrel's killing off the red, well at least the virus it
carries is.

Er, no. *It isn't significantly more invasive than the native one.
It is a bit, but not enough to get excited about.

Let's not forget that gardeners introduced Japanese Knotweed,
Hilalayan Balsam, the so-called "OxfordRagwort" and others. OK, maybe
the last was introduced by botanists not gardeners.

Only the first is a serious problem. *Himalayan balsam is very
invasive, but does not form monocultures by excluding all other
plants. *And Oxford ragwort isn't a problem at all.


I do wonder if the comment about Oxford Ragwort is motivated by the
general hysteria about ragwort that is prevalent. Often stirred up by
by those with a financial interest. Common ragwort is not the problem
that it is often portrayed to be. See. http://www.ragwortfacts.com
