I have never planted these but they were on a very small list of dog safe plants that I can put in my backyard where the dogs play. I bought 20, different types but I don't recall the names at the moment, I can get them if it makes a difference.

Some are heucherella.

I am south east coastal NC and my backyard faces East I believe. It gets morning sun, until noon and then my house shades a small portion by the deck. Could these take morning sun until noon? I have another spot in the back area that gets even less sun if they need it they can go there.

Do they like a lot of water? I have astilbe planted back there and it does well would they be about equal with that?

For comparison i had ferns where the astilbe is and the ferns did not like it and needed to be moved to more shade and damp area where my hostas are. I think the hostas would do fine there but can't go there because of the dogs.
