Mystery plant but looking great - Any name please!

LToby

Last Spring I found this small plant underneath my other plants. I potted it with a petunia (the red flower on the image is petunia). It grew very well with beautiful leaves. The foliage changed colours during Autumn, then it will lost its leaves for the Winter. Its coming back again, so  I thought I would ask your expertise in identifying it. Thanks you very much. Images are below ...




Thank you once again for all your insights. More power to the Gardeners Forum.

Could be Rhus typhina (Staghorn Sumac).
It may have been a runner from a tree nearby,maybe from a neighbours garden?

Thank you madpenguin for your immediate response. It looks like a big tree :-)

Looks like a rowan [mountain ash] to me
Birds spread them easily by seed.

As always, Thank you so much for the responses from Madpenguin and Fairygirl; greatly appreciated indeed. It is something that is unique in this group, a very constructive insights of gardening enthusiasts and experts. 

Today, I looked around at our neighbour's gardens and found that there is one Rowan tree (Mountain Ash) around and nothing to be found a Rhus typhina (Staghorn Sumac), even called a neighbor to see if they have a tree of that kind. I was told never have of that type in their garden. 

I did my research, and found that the closest ID based on the characteristics of the leaves, the bark, roots, and seasonal foliage, it is indeed, Rowan (Mountain Ash) Tree. And must have been planted for me by one among our friendly birds that frequent our garden, of which I picked and potted it. 

I like the plant (Rowan - Mountain Ash), and thanks again for the insight of Fairygirl. Cheers!
