Howdy Maxyck!

I can't comment on the baggie method personally...but I have read it works fine for R. hirta. This website talks about it: Rob's Plants. Looks like it requires quite warm baggie temps to germinate.

Ps.
I've started that Rudbeckia via the winter sowing method some years ago and it worked well. I believe a GW bud of mine usually starts hers under a grow light early spring with beautiful results...

Like CMK, I too have had success growing Rudbeckia hirta cultivars via the winter sowing method, among them Cappucino, Cherry Brandy, Autumn Colors & Irish Eyes, as well as a number of others. I find recycled milk jugs to be more effective protection against the ravages of winter storms--ice, snow, & wind.

Winter sown plants are much more robust than their nursery-grown counterparts--many of my seed-grown R. hirta cultivars have returned every year since they were first planted in 2010. Since I mulch heavily over corrugated cardboard, I'm assuming the plants return rather than self-seed.

Not sure what the baggie method is....?

I do winter sow, and I have very successfully winter-sown many varieties of rudbeckia hirta. Personally I would most likely not use any kind of baggie method but only because I prefer not to buy plastic to use if I can re-use (and then recycle) other containers. But if by baggie method you mean some kind of winter-sowing, I would think it should work for you.

-Dee, this is what the 'baggie method' is: info here ;-)

I've had good germination of numerous types of Rudbeckias through routine planting in sterile grow-mix - no need for baggies, filters etc.

Oh my goodness, lol - too much work for me! And too much waste. I suppose for some hard-to-germinate seeds, something like this is good, but I just most likely wouldn't grow those things! Not knocking it for others; it's just not for me.

Thanks, CMK, for the link. I was thinking of something a bit different.

-Dee, ha! Me too. I've tried it a couple times and ended up forgetting them in the back of the fridge for four months, LOL!!!

R. hirta is easily grown in the baggy, or out of the baggy. No need to mess around on the easy things. Look how eager the species is to multiply in the garden.

"I've had good germination of numerous types of Rudbeckias through routine planting in sterile grow-mix - no need for baggies, filters etc." ... indeed, just surface sow these upon a good quality starting mixture and keep covered to maintain moisture until seedlings are up and running ... they're sooo easy!
