2015 Purchased 3 from Lake Street Garden Center
I grew an entire pack of seed of regular D. barbatus and did not end up with a single white flowered plant. I did get a lot of seedling die offs so perhaps the white is the least hardy. I am dying to get a white fragrant Dianthus in my garden en mass so I saw these at the garden center and had to get them. I can't notice a smell however they are just beginning to bloom and I know some flowers only smell at certain times.
