Don't you mean that the habitat was ideal for the species? Generally, invasive species tend to alter habitats beyond recognition, which is why organizations like the Department of Water Affairs have conservation programmes they call 'alien invasive species eradication programmes'.
Yes, if the exotic species is introduced into a habitat that suits it, it could become invasive. With the protea variants, that would not be the case, because there already is a better adapted variant.

The Water Affairs conservation programme is to a large extent focused on water conservation, so they target invasive species that are aquaphilic. Promoting indigenous flora is a secondary effect.

Very nice, Hermes.
Belatedly, thank you!
Compliments embarrass me. :-[
