sorry I dont recognise it but isnt it pretty?

A young Ligularia przewalski - they have serrated leaves like that.

I don't believe that is a ligularia................. I think it is Sinacalia tangutica. A plant with very 'architectural' leaves. horrid yellow flowers, and I bought one for my woodland. It behaved itself for the first couple of years, so I transplanted a small section to my garden. BIG MISTAKE. It's a thug, the roots are tuberous, they go down a good foot in some sections. I removed it from the border a couple of years ago, but I am still digging out sections. It even manages to come up in the lawn about 4' away.
To see my plant check out the link..... by copy and paste.

Actually I agree with 2ndhand. Ligularia has spikes of yellow flowers and the photo has multiple ones that just does not look right - and it does look like Sinacalia tangutica!

Geoff Hamilton grew this with other thugs in an island bed so they just battled it out with each other and any that strayed out of the bed got mown off.

Thank you, 2ndhand. I think you're right! My friend told me it might 'take over' which is not like Lig. behaviour.

Well, it's next to a patch of Lysimachia punctata, so they can battle it out between them. ;-) Actually, I quite like it - at the moment.

Mmm, well it got ousted from my garden borders as it is yellow. Had it been a nice purple or pink it would have been allowed to wander. :-)

It's on the stream bank with the amber, gold, purple and yellow toned plants - so it looks fine there. :-) It isn't in any shade, so maybe that will have an effect on its growth.

I think you will find that the light levels will have no effect on its growth rate. My Om finds it absolutely fascinating. When the sun hits it the leaves droop, I was initially told I'd planted it in the wrong place it was dying. But as soon as the sun moved off it, it stood up all perky again. I very nearly got an apology. :-)

We haven't had a lot of sun for me to take time out to observe it, but now you've said that, I shall take a look. :-)
