My sunflower also arrived today, well packed and in good condition. I got the 4" pot. 6 healthy leaves (although a scratch across the width of one of the lower leaves) and a 3/4 inch new root sprouting, plus a new baby leaf. Spagnum was pretty moist. In light of your experience, I'll have to pull it out of the pot later, when I have time, and check the roots. Those I can see near the surface look healthy.
