I have germinted sintenisii, but can't say what did the job. I planted
seeds, chiilled them, but no germination. Seeds were dumped (after
second winter and no germination)
, along with a bunch of others. The
next year some of these seeds germinated. They went through a second
winter, with freze thaw etc.
But, they are a spuria species, and often the spuris seeds germinate in
early fall. I didn't note when the seeds germinated, but some in that
batch did germinate in the fall, and there were a number of
differerent spuria seeds in that patch of ground.

Most of us haven't had such easy germination with sintenisii. Are
you starting with fresh seed, or has it dried for a while? And when
does it go outside, & for how long? Is it subject to freeze & thaw, or
cool temps gradually warming up until summer?
