I know that liriope is evergreen in Savannah where I used to live, but is it evergreen in Northern Virginia. I'm playing with the idea of using it as ground cover for under some trees in the front of the house. There is enough shade that grass is struggling. There are also some shallow roots.
I'm thinking of the type with white flowers. I figuire I can put it in in a couple of weeks - if it is evergreen.
