&gt; Surely there are similar environments which might become home to a transplanted variety, the danger is that its no invasive or dangerous to other specie.<p>This happens all the time. For example the giant hogweed (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Heracleum_mantegazzianum" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Heracleum_mantegazzianum</a>) was introduced in Europe as an ornamental flower. It displaces native species and on top of that is highly phototoxic.
