Professional Growing Information 
Contributes such a unique color to the flower bed. Fills in a space nicely. My only criticism is that it is the first to wilt when it goes more than two days without water, but bounces back quickly once watered. Looks nice paired with chartreuse foliage, pink or orange flowers, and red or bronze coleus.

This was my first time for alternanthera I have the purple Leaf and it did great during the North Texas summer. I had it in my yard in a container but it was to hot and had to be watered twice a day.
