I don't know any of the parents on these. They were the result of leaving seed heads over winter.
They were coming up everywhere. I will never make that mistake again. Most I just tossed. No rhyme or reason on which got tossed and which were put into a tray. They all just looked like minute green things. I didn't even make a note on what bed and area of the bed they were coming up.
This year is the year of the sedum seedlings. Again, they are coming up everywhere.
