@WanderingHuman@cosocial.ca I think those are a type of dianthus (a genus that includes smaller "pinks" and larger but not Edmonton-hardy carnations). Yours look like the ones I have that were sold as annuals under the name "pinwheel dianthus", but which have been coming up vibrant for a few years now. Any chance it's the same situation for you? Perennials that you expected to be annuals only?
