whats a soil basket.. and why do you get soil from your neighbor ...

Looks like one of the long stemmed/trailing petunia varieties, likely a seedling from something like a Wave petunia.

The flower certainly looks like a petunia, but the alternating leaves don't look like the leaves on the pots of petunias I have.

Petunias can have alternating leaves. They have them in the lower parts of the stem and they change to opposite as they get smaller nearer the tips. I think Petunia x hybrida has entirely alternating leaves. Petunia x hybrids.
