I think that either he or you didn't mean to type that, unless he is
using a new and extremely bizarre meaning of the word "native"!
It is more traditionally called "of garden origin".

If he is, what his his criterion for distinguishing naturalised plants
of garden origin into "introduced" and "native", remembering that the
very concept of "species" is almost meaningless in many such cases,
and that the same cross is usually performed many times in many
countries?
