Carex ‘Feather Falls’.
This grass has not only survived but thrived in full sun here in zone 6B New Jersey. It looks great in mass at the front of a garden bed and as you can see below, retains its color and shape into winter. You can read more about it here. As mentioned in this write-up, it kicks the ass of the Liriope and I plan to add more this spring.

Oh, I like that one! I don’t think I have enough sun for it in my garden, but it’s lovely.
I am also becoming a fan of the Carex (carices?). Received a freebie a few years ago, with narrow leaves and frosty color (forgot the name), which has survived a couple of moves in the garden.
More recently I tried “everillo”, which I’m loving – will get more this spring!
The deer love eating my liriope to nubbins. Do you experience the same with carex grasses? Thanks for these posts!
Glad you asked. The deer dug through the recent 10″ of snow to eat my liriope. I would certainly entertain the thought of a replacement, especially around my front stoop which currently has clumps of dirt frozen in the snow.
