It's a Hibiscus moscheutos cultivar. These like full sun, regular water, fertilization during the growing season and a position located out of wind.

If those three are all supposed to be in the same series they do not have uniform foliage characters, with the first one having the undivided leaves of H. moscheutos and the other two having cut leaves that demonstrate a clearly hybrid nature.

Of course, most H. "moscheutos" cultivars may be of hybrid origin.

Thanks to all.

Popamama, I am thinking my wet area around the fountain is out. The leaves and flowers would likely fall in the water and clog the pump, we couldn't easily get around the plant to cut off spent blooms, and it is partial shade.

But now I'm in a conundrum. The other area I was considering had Chuckles roses in the spots. But these are partial shade also. Looks like I need to find another spot or take them back to Lowes.

Does anyone know how it does when it gets hit by over spray from the yard sprinklers? Does that ruin the flowers?

Sprinklers do not ruin the flowers. Keep in mind that the flowers only last one day but there are many, many buds per stalk.

And yes, these are all different hybrids. Some of them have heart-shaped leaves and others have the maple-shaped leaves. I was presenting some of the varieties I have in my yard since I live relatively close to the original poster. They are very popular here because they seem to withstand the hot, dry climate and take a lot of sun.
