Rudbeckia not germinating

I planted Rudbeckia Gstrom seeds in Feb and end of March - both batches have not germinated.  I covered the seeds with a fine thin layer of seed compost - does anyone know why I have no plants this year please?

    Do you mean R.goldsturm
    He calls her the chocolate girl
    Cause he thinks she melts when he touches her
    She knows she's the chocolate girl
    Cause she's broken up and swallowed
    And wrapped in bits of silver

    Sowed way to early and did you have them heated.

    Hi Andy this is my first year of owning a greenhouse so apologies for asking what do you mean did I heat them?

    I sowed some rubekia and the germination rate was low plus the seedlings seem slow to get a move on but I'm hoping they will get there. 

    I used a propagator with bottom heat and they are now in a mini greenhouse. Have you got some more seed to have another go now it's warmed up?

    Hi deb no problem we are all still learning everyday in life. Seeds can be a hit or miss sometimes as everyone has experienced in gardening. Don't let it put you off its great growing things from seed instead of buying you appreciate it more good luck.

    Thanks Andy, I'll keep trying - really enjoying it at the moment (even the failures!) Good to know it's not just me.

    February is very early to be starting seeds, they may have rotted if they were too cold and damp.  Now is a great time to resow if you have more seeds......

    I find Rudbekia sometimes ‘iffy’ to germinate too, like last year. This year 50% germinated. So don’t worry but agree don’t start sowing so early...March is fine for them.
