Re the non-native Nazi attitude. The term "invasive" or "alien invasive" have
very specific definitions. If a person in your climatic region is concerned, all
they need do is go to the State or Provincial invasive plant folks, and look at
their list. In Canada, (BC) the agency is called the "Invasive Species Council"
and, like all these agencies, has the job to educated as well as control
invasives, be they plants, insects, and other animals. Also remember that what
is rampant -- perhaps even invasive -- is almost always climate specific. My
sister in New Mexico, babies a lovely delicate variegated vine on her portale.
It is English ivy which, in the Northwest actually twines around and kills
250-ft cedar trees.

From Michael Mace....." . If we compile a separate list and label it "invasive"
or "potentially invasive," I am afraid that it could be misused by people who
are trying to ban all cultivation of non-native plants."

Michael is absolutely correct.  Crocosmia is an excellent example.  Perhaps
there are named hybrids that don't spread as badly or don't spread at all in
hotter, drier climates.  Who am  I to deprive someone of 'Lucifer'
(Brilliant red Crocosmia hybrid) if they can barely keep it alive.  Here on the
southwest coast it is a major problem, especially because it is a bulb and is
quite capable of remaining dormant for years until uncovered.

Then there is a concern for Cyclamen coum getting out of hand on Vancouver
Island, BC.  I will tell you that mine, mature as they are, are having a very
tough time in my garden resisting the onslaught of two tennis-ball crazed dogs,
and even where I dump old potting soil, C. repandum is actually doing rather
well compared to C. coum.  Life is in the nuance and even more so in our
gardens.

And let us not forget the rumor mill among gardeners -- So and so will say "Oh,
that's on the noxious weed list."  Well, I checked the noxious weed list for
Oregon and it's not there at all in any format.  Not that it should or shouldn't
be, but word of mouth needs to be verified from various sources, i.e. history of
native habitat, climate and micro-climate, growers'
experiences, etc.  Whenever I'm reading about a plant I particularly want to
grow, I check habitat, soil and so on and run it through my mental software that
translates where it's being grown into my particular micro-growing conditions.
