But by the unwelcoming answer I'd have to guess that's a 'No, I wouldn't share my stevia plant or their seeds with you' . Know any other way I can get it here, though, without having to go through the complications of bringing the plant here anew from overseas ?

The answer was not negative.
You can have a plant or some seeds.
When the plants dry out they run to seed and so seem to reproduce easily.
