Germinating rhubarb

Hello. I have harvested a lot of rhubarb seeds. Can I germinate them this year, at this time, or is it too late? I read they don’t require cold stratification, however, I’m not sure if they need a longer amount of time to establish before the zone 5-6 winter.

We can get our first snow in late October, early November and I’m located in southern Ontario but have two places I could grow them that are about a half to 3/4 hardiness zone difference.

Thanks!
