Quaking grass Briza Maxima

I’ve used some in a bunch of flowers. It looks great and I’ve bagged some of the seed heads. I really like it because it just looks like grass, then this really weird, textual but delicate thing grows out of it    .Also sown the last of the seeds from veggie and they are coming up   . No idea if sowing them now is wise. But I’ve been at the seed sowing school of veggie for far to long to be worried about the correct sowing times     .

You have to think like a Weevil grass.  "Am I ready to scatter my seed at this time of year so they grow next year in every spot that will really annoy the weevil hating gardener?"
If so,  Sow.
