Those are not foxgloves, FshyPlnts. They are Chelone, aka Turtle Head. I suggest you pick the pods which are brown and open, ie the lower ones, and just tip them out to extract the seeds.

Hey!
So that shows how much I deal with outdoor plants :). I got the two plants I am dealing with confused. Are foxglove ready the same time? When the fruits brown? Also, I tried the method you described. It seem like a lot of work. Is it possible to separate the fruits and plant them in their entirety? Thanks for the help!

Foxgloves were ripe a long time ago in my climate so you may have missed them. I don't really consider tipping a few pods out 'a lot of work' but I suppose you could wait until all the pods are brown and shake the whole stem to get the seeds. I can't help you with whether it's good to plant a whole pod. Some people do it but I never have. If you consider that each pod contains many, many seeds you would end up with a thick clump of seedlings which would need thinning anyway. Sprinkling them thinly onto a flat or seedbed doesn't seem too difficult to me. You don't need to sow them individually. Just take a pinch between finger and thumb and sprinkle.
