It's Rosa moyesii, sorry about the writing .
I sowed mine in 2 batches and the over wintered ones did best. Might be worth putting some in the fridge for a while as an artificial winter. But as things are this year they'll probaly be chilled outside. Did I send you enough to do some in the fridge and some in a pot outside? There's still a few here if you need some more.
Don't sow deeply. Light may be required. I covered mine with vermiculite.
Years ago I poured boiling water on rosehips to make rose hip wine. After I strained it I tipped the remains on the garden and a rose forest germinated. Dog roses though, not rugosa but worth considering
