Hi, I'm doing some 3 ft. long low containers on a terrace in NYC- it's a north facing garden- only gets a few hours of sun a day and it's very windy (25th floor). I just bought some dwarf mondo grass (see image) for the containers and I want to plant some flowers in between for color. Does anyone have any ideas of what would be good? It's going to have to be a shade loving, low-growing type of flower. Thanks for any suggestions!
