Was anyone suggesting it would?

No, but somehow we should encourage all flowers to grow, a variety of
plants to support a wider range of insects and not stick to 'native'
only. The example I give breaks my heart when I see it.

I don't know what EN are recommending or why. Stace describes V
officinalis as native and I have seen it growing in the wild. I have not
seen V bonariensis in the wild. Stace describes it as introduced-casual,
on tips and waste ground.

Introduced-casual is something I haven't heard off. It's interesting.

It's flawed in that most of our flora and fauna probably came from
elsewhere, if you go far back enough in time (the alternative is that
the species differentiated enough to become a true species actually
within what is now the UK), but for practical purposes there is a
distinction between species which have been growing wild for long enough
for their origins to be uncertain and species which are known to have
been introduced.

Sounds like the grey squirel V the red one ) I understand the dangers
of loosing a plant and even more an animal specie. Though I wouldn't
worry planting V. bonariensis and marguerite in a garden.

As I said elsewhere, if the species in question is one that originated
in a similar habitat, with similar flora and fauna to ours, then it will
support our species. But if it is from somewhere entirely different,
then, while it may support some of our generalist species, it is
unlikely to support our specialists.

I understand and agree.

There are a large number of people who think that our native flora are
worth preserving, and that one should not plant introduced species in
the wild. The ill effects of planting introduced species in the wild
range from pure competition ousting native plants from the area
(Rhododendron ponticum, Himalayan balsam, parrot feather for example) to
cross breeding with natives (eg spanish bluebell) with effects that we
do not fully understand.

I understand. Thank you for taking the time with this. It's very much
what I thought - I feel however our main problems are pollutions and
chemicals, monoculture and the weird weather we're experiencing. I do
think Spanish Bluebells are pretty, but I am a firm beleiver that the
more flowers I plant in my garden, the more prolific my garden becomes
in insects and birds, and I am not really found of R. ponticum,
himalyan balsam nor parrot feather ))) So the UK wilderness is quite
safe whilst I'm around.
