Whats the MOST cold hardy grass avlbl?
I need ideas for 4 season planter setup.
I have a big pot 2'wx2'h and round in full sun. Right now has 2 Osteospermum(white,pink), 2 Sweet potato vines in front trailing(one green,one black).
I need to put some kinda tall grassy spikes in back. Is there an evergreen for that?
If none, then is there a very (most)cold hardy Tall grass that stays intact in winter and comes again in spring ..inspite of being in a pot in s.e.PA?
