Hello Doris, According to the article (link below) that the following quote comes from, yes, phlox do reseed each year, but ... " ... Phlox are very easy to increase by simple division, in late summer or early spring. Commercial growers tend to propagate them using root cuttings taken in late summer. Stem cuttings can be taken in early midsummer, but only do well if kept in very humid conditions, such as in a mist bench, or at least enclosed in a plastic bag. The success of the bag method depends on close attention to cleanliness in avoiding fungal rots, and ensuring the light conditions are neither too dark nor too sunny. While phlox start easily from seed, and often self-sow into the garden, it is rare for the seedlings to have the same coloring and habit as their parent. In fact it is good policy to deadhead your phlox before they go to seed, as those little self-sown seedlings tend to grow up into vigorous plants of a decided magenta hue and can, in a few years, crowd out the mother plant. In our fields we will go through every year looking to uproot these rogues, and we find new ones every year. (Of course once in a while these seedlings create exciting new plants, so we like to pay attention before we pull, and so should you!) ..."

phlox is a perennial that often sends seedlings elsewhere in the garden
they come back each year. They do reseed but not very fast to spread
The only thing I know about public is it's a perennial, and ours came back every year without any problem. It does spread!
Yes, they are a Perennial.
