I am curious if anyone who has gotten S. rosea seeds from the seed bank to germinate? I did my usual stratification process, but I have gotten zero germination. Is it me or the seeds?

I got great germination, probably 80% or better. However, they grew to about 1/2 inch and all seemed to dry up.
Maybe I got an invasion of fungus gnats, because a couple other Sarr pots did the same to an extent, but not all of them in those pots. Whole other Sarr seedling pots in the same tray, right next to those afflicted, had no issues.
They're outside, so I'm going to leave them be and monitor for any changes, but I'm almost positive they're done.

I got about the same germination rate as Chef. They have been outside since I took them out of stratification, on a covered back porch getting morning sun until about noon or so. I'll try to get a picture tomorrow if I remember.

As usual, my photography stinks, but here's what they look like today.

I think i remember the short tubby sarrs need a longer stratification.

It was probably around 5 or 6 weeks, but if I read at the time what optique says, I might have left them in for longer. It is likely to be longer anyway because I tend to forget them behind all the junk in my refrigerator.
