I planted some from seed last year, Galardia Burgundy (from Swallowtail Seed). It took until close to fall to get blooms and I didn't expect them to return this year, but I have several of them that are setting buds like crazy this year. I rechecked the site and it says winter hardy to zone 2. One of my Rudbekia came back too and it is only supposed to be winter hardy to zone 5, big surprise there.
