poisondartfrog said:Maybe stratification for this species is over-rated? When I checked my pots on heat mats this morning looking for germinators, the only one of this group I placed on heat had germinated. It is Calycanthus floridus #2 on my log; a seed from one of the two that are of uncertain parentage. That is 34 days since I scarified and put them in a hot water soak.
Later today or tomorrow when some of the soil falls away from the seed capsule as the cotyledon continues to emerge I will take a photo and post it.
There is no sign of activity among the wintersown examples. I am wondering, JB, if they could have been pre-stratified naturally if you left them on the bush well into cold temperatures for your area?

You might be right Alana. Really looking forward to your experiences.
But anyway, it's much too early to expect any germination in the winter sown containers here. Too cold.
If the Sweet shrub is really hardy to zone 6, it's not a problem to winter sow them.
I'm curious about how the seedlings will survive and grow further in different circumstances.
Which ones will grow better: the ones who were grown on heat or the ones who were winter sowed?
Very exciting to follow this experience
