narrow leaved echinacea, a native species

narrow leaved echinacea, a native species. I divided these small trays of starts and transplanted into large plug trays, will see how they do. echinacea is a perennial wildflower, so I'm thinking they'll be trimmed and offered as dormant plug in the fall or next spring. just getting into more herbaceous perennials and sorting out the best way to grow them and send out to people.
