Shelter for frogs sunning themselves on edge of pond?

[jay moussy]

My inherited pond has/had a thick English ivy growing on the roundish rock pond edge. I took a great deal of it down (to be replaced by TBD).

It just happens that frogs seemed to like sunning themselves, hiding among and blending in the flat part of the ivy vegetation.
Now that it is gone, what could replace it, be it vegetation, or some man made contraption?

Creeping Jenny, Sedums, Creeping Thyme, so many others just found at a garden store that like to crawl.
Creeping Jenny w/little yellow blooms(it loves to take over but easy to pull out where you don't want it:

Creeping Thyme:

Low crawling Sedums like the Stonecrop different colored blooms to choose from

Lots of other varieties of crawling sedums:

You could consider a native groundcover.

Phlox subulata (Creeping Phlox) is just outside of your native range, but it'd be a nice one.
