I'm looking for something to replace the dianthus I had growing in this bed. It was an annual and came back last year unexpectedly. I absolutely loved the pop of color and fullness, but unfortunately my luck has run out with them as they did not survive last winter. I'd like to find a perennial similar to the dianthus, but I'm not sure if one exists. Also, don't mind my dog, this is the best picture I have of them from last year :)
