These phlox grow wild all around. The purple is the easiest one to get seeds from if you want to try to naturalize some in your flowerbeds. I do have a small amount of pink and white ones growing in the fields this year so I may venture out to try to get seed once they are ready. I love the way they look for a background for some other early bloomers. Seeing as I haven't had much time lately to work in my gardens I thank you for posting pics here chico. They look nice there.
Of course those black and white flowers are a couple of my favourite ones around.
