Most cause no problem at all, but some thrive in our climate
and soil and become invasive. Together with habitat
destruction, invasive species are the major cause of extinction
in our world today.
In Kew the Yellow Perfoliate Alexander (Smyrnium
perfoliatum) seen in May, is an example of a species that
has become naturalised in this area and does rather too well!
