I'm sure your hostas will need more shade and more water than they do up north so plant them where they will be convenient to water without dragging a hose around to all four corners of your yard. If I remember right, heucherella can't take the heat as well as heuchera. Maybe someone else could comment on that. I'm in southwest Missouri and heuchera has been hit and miss for me but most have done pretty well. How far south will you be in Arkansas? What kind of trees are you planting them under.

The new fancy heuchera tend to do poorly here (at least for me). Hostas can do quite well, but they can also be under siege from voles, and many have never seemed as lush as I've seen farther north.

Hydrangeas grow like weeds, and you can expand your types, consider H quercifolia, it's lovely in pretty much all season.

And remember, your palette will be wider with cannas that overwinter in ground, crinums, sabal palms, lantana, winter-hardy cacti if in well drained SW Arkansas, etc. Don't just stay stuck in the northern mind set, we have more to offer. The last few years, bananas are appearing heavily in the local urban landscape....

Thank you for the replies. I will be around the Batesville area. I'm moving my hostas into a holding bed getting ready for next spring. I'm getting older and need to downsize anyway. It's just hard to decide what to give up. I'm sure the hydrangeas will make up for other things. I do plan on placing water on all corners of the yard. I hate dragging a hose around. God has blessed us with enough rain this year that I've only had to water once. I will have to look up some of the plants mentioned. Looking forward to new adventures and thank you again.
