Last year I grew Rudbeckia from seed, can't remember the variety, and they came up fine.
I started the seed in coir in a propagator with a plastic lid, on a table in the house near a window. I think I had a heat mat under them until they germinated.
Hardened off then moved outside eventually into pots.
I sowed them sometime in March, this was them end of March
Not sure that will be practical help for you but maybe some hope
That looks like Rudbeckia hirta, which is probably easier by seed.
You might improve germination if you cold stratify, Simone. I am trying Rudbeckia triloba this year, and although it is supposed to be quite easy and should flower well from an early sowing, cold stratifying was recommended.
BTW my local GC had 5 x 9cm pots of Goldsturm for £10. Or you could buy a 3L plant and divide it. If you aren't wedded to the variety, Special Plants have 10 divisions of Rudbeckia missourensis for £10 (+£4.50 P&P)

Hello Rose, I will give it try it at the end of March again.
Purplerose, the Echinacea from the GW issue took 10 days before they came out.
Dirty Harry and Loxley, the reason why I want to grow partly my plants from seeds is that I have so many plastic pots collected over the years that I thought there must be more efficient way. Good news is that garden centres start now to use other type of pots, for example the Rudbeckia Goldsturm that I bought as a young plant last weekend came in a compostable pot.
I've also struggled with Rudbeckia 'Goldsturm' from seed. They are slow to germinate, mine took about 5 weeks, and not all germinate at once. Sowed them in the last 2 years, first year managed to get 6 seeds to germinate, of which only 1 made it through. Last year 9 germinated, of which 6 made seedlings. Looks like I might be getting more successful at least. I planted out late summer and the seedling from year one flowered last year, I am therefore hoping that the 6 from year 2 will do so this year, and hope that I now have 7 mature plants. Not bad out of 200 seeds! I find them a challenge to say the least.

I am a newbie gardener to seed sewing.
