Great hardscape! What plants are you planning to use?
Right now, just Dwarf Hair Grass, or what I think it is. I am also trying some Helanthium tenellum to see how it works. I really don't know what I want to use, I just had the DHG so I started with that. I think it's height could make it look really good, or really bad. HC would have been my first choice but I am kind of sick of it. Outside of HC, I want to use a grassy plant.
Now, I don't know what I may add after that. I may keep it as just one plant, I may add on. Too early right now to make up my mind. I don't see much going on plant wise though.
