I think Alternantheras ARE cool. A little easier to keep happy inside over winter than Coleus, but with the same ease of propagation, fast growth, and beautiful selection of leaves to brighten the landscape. From what I've read, our grandparents/great-grandparents would have referred to these as calico plants.
I wish more of them were in mass commerce.
It looks like some form of A. dentata behind, the pretty purple leaves.
