Grim the collier. Pilosella aurantiaca. A seed and creeping thug of the first order.

Another common name, Fox and Cubs.

I agree with the id's given.

Many thanks and this is interesting.

I most certainly have not grown this and doubt that my neighbours have. However.......... having bought seed online in the past few years, I have often been annoyed at the poor germination or the results of the germination. I remember sowing some primrose and they most definitely were not primroses when they germinated. Same goes for a few other plants. So, I am wondering now if they are selling 'weed' seeds.

It's a weed in my garden but it is pretty so I leave it alone.

'Fraid it's gone now! I am sure this may have been a freebie when I bought some seeds online. They occasionally send things like Californian poppies, etc. Easy germinators but pretty much weeds.

I can't possibly think of californian poppies as weeds!¬ They are a childhhod favourite. I used to so enjoy visiting my neighbour's garden and ]being allowed to take the nightcaps off the ones that were ready to open...

Steragram, they are pretty. But when they are growing out of every possible crack in the patio and under every shrub they become a bit of a nuisance. :)
