Can anyone tell me how to grow herbstonne from seed.
I've tried many times with no luck.
It's very difficult for me too. I got one germination last year out of hundreds, but the squirrel destroyed it when I set the little pot out in the garden. Poofed!
I dont know how you tried to germinate but I have success with.... lightly cover the seed SOIL TEMP 70-75F took 4 to 45 days to germinate & 10-14 weeks to set out green.
Pretty much do that.
Good to know soemone's had success.
Don't have problem with others in rudbeckia family
Guess I'll keep trying.
