Dianthus Spotty is a low gray carnation that can fit into the rock garden as well as it does the perennial bed. These gorgeous 3/4" blooms will put on a show all spring. I love the intricate detail of the markings. Dianthus spotty grows to 18" across and only 3" tall. I have had the same plant persist for 6 years and going strong, so long as I don't let its neighbors swallow it.
