Hello to you Patty! We are limited in our zone but certain Miscanthus sinensis cvs. and Carex muskingumensis are a couple of other options.

M. s. 'Sarabande', 'Strictus' (could be too tall) and 'Morning Light' are very hardy.

I grow C. m. 'Oehme'

I am a fan of Panicum and my favorite is 'Shenandoah' but it does require full sun.

How wet and for how long? A great many OG's are just as intolerant of overly wet soils as are most other plants. I would stick to sedges, Carex species, if consistently wet. But Calamagrostis, Molinia and Deschampsia will tolerate periodic wetness.

You might want to Google rain garden grasses for your area to get other possibilities.

I recommend Switchgrass. It likes wet, tolerates standing water and is recommended as a stabilizer in wet areas. Its also native. Besides tolerating standing water it also tolerates heat & drought, is very cold hardy & easy to cut back in late winter because it doesn't have sharp leaves like Miscanthus. My favorites are Northwind and Heavy Metal, both are very vertical.

Avoid 'Prairie Sky'. It tends to flop when too wet.
