On second thought, maybe I will take some columbine seeds. Columbines do very well here, but I mostly have blue and yellow.
The penstemons self seed so I would think you could sew them now. In the past I've grown P. strictus by collecting the seed in the fall, storing it in a baggie in the fridge all winter, and then sewing it in flats that were outside in March so they got good and stratified. On the other hand, the P. strictus self seeds really well too, so I probably didn't need to go to all that trouble.
