It a Rudbeckia aka Coneflower. Lots of different varieties.
Pretty flowers - Must be very unsettling for you!

Thanks and yes, first urge is to get the weedkiller out!
But as they are not in my garden I sort of refrained.

Looks like
Rudbeckia fulgida 'Goldsturm'
Do they last ?
Thanks

Never grow them myself, but I think they're longlivers.

Fantastic as a cut flower and should come up every year...mine self seed.

Years ago I went to a stately home that had very little funding to pay for all the gardeners it needed to maintain the gardens as the Victorians had planned them.
There was a splendid bed full of Rudbeckia - really eyecatching. The gardener told me that they just scattered the seeds on the soil and let them get on with it as it was a cheap, easy way to fill a bed and needed little maintenance.
I've tried this several times and can't get them to grow

The gardens look a bit better now - https://www.nationaltrust.org.uk/dyf...es/the-gardens

Last year a neighbour had a nice display of these next to the footpath. In Autumn I "acquired" a couple of seed heads and kept them in an envelope over Winter. Last weekend I sowed them in a heated propagator.
I shook them out there were hundreds of seeds.
But none have appeared as yet. Do you think the should work ?

Thanks

I have Rudbekia Cherry Brandy, grown from seed, in a pot which I bung in the greenhouse over winter. It's been coming back for 4 years now, and at first I thought it must be a tender perennial til I realised it was self-seeding

So yes, I find them easy from seed but I've never worried about how long they take to germinate. Google says they can take up to 3 weeks

OK Thanks , patience is a virtue, which I have little of !

I grew rudbeckia ‘green eyes’ from seed last year. Due to neglect I only got two plants. But my goodness they bloomed and bloomed. Cut loads for house. Definitely growing again this year. Very fiddly wee seedlings though.

Still no show after 3 weeks at 20-25 deg C
I saw this line which suggests a period of cold.

As per
If there is no germination in 3 to 4 weeks remove to a cold area for 4 weeks, -4 to 4�C (24 to 39�F) then place back in the warmth, this should trigger germination.
Any one else heard this ??

Yes Jimmy, quite a lot of annuals need a period of cold to trigger germination. Stratification is the term for breaking dormancy artificially by cold. It's quite common treatment for seeds as many seeds require a period of cold (winter) before being able to germinate. If you have gathered the seed in autumn and then kept it somewhere indoors the seeds may not germinate. This is often why things seem to self seed well but are difficult to grow by growers.

**Jimmy** · 17-04-2018, 01:24 PM

Yes I nicked the seed heads last Autumn and kept them in an envelope in the front room.
There were a few left, so in the fridge for a spell and try again !
Thanks
Jimmy
