Anyway, in the vernacular, 'wild' includes 'naturalised'. Let's ignore
the detail that the difference between 'naturalised' and 'native' is
more a matter of religion than science, for reasons we have discussed
before.

Stace includes native, naturalised and casual species. I didn't go to
the trouble of separating out the native from the naturalised roses, so
the 20 wild species includes both native and naturalised.
