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. I moved it closer to the patio where it wasn't in the direct heat and it did much better. This will be a regular in my garden its stunning...Delores Chambers, Texas, United States, 2 years ago
