The real work of art here is the cast iron urn. It is one of my all-time favorite pieces and with it, there's not much chance I'm going to go wrong, no matter what I plant in it. Still, one has to keep in mind color and proportion so that's why I chose this Carex grass. First, the shade of green is a nice complement to the bluish hues of the urn. And second, the height and growth habit of the foliage make the whole thing work.
Carex is perennial to zone 5 and appreciates partial sun. It's a slow but steady grower and, like almost all plants, requires excellent drainage. So there you have it. Life is complicated enough, but your garden doesn't have to be.
