I bought those awkward named plants from Parks Seeds last year. They arrived late in the season, and didn't flower at all until late August, They need to be deadheaded in order to produce more flowers, and I did that for a while, but I don't notice any seed production on the few flowers that I let go to seed. I will overwinter them inside (they are tender biannual) and propagate them from cuttings as I think that can be done, but I would love to get seeds. The bees and butterflies don't seem to visit them. Is that doable ?
