Im unsure of what it is, but whatever it is...its sure hardy! Some plantlets that dropped from the leaves are trying to sprout in the sidewalk! I'll get pics up soon for an ID.
Anyway, I've got tons of seeds and quite a few baby plants. 2 baby plants are larger(several lanceolate leaves), if that matters.
I would really like S. leucophylla with a location attached. But you could try with something else if you wish.
