Tree ID needed :)

Had this self seeder in my garden for about 10 years now and it's been slowly growing uninterrupted by my various plans. Always produces good sized leaves so is in keeping and is nicely tucked away. Seems to like the extra light its getting following a chop down in my shady jungle.

I have the name of it on the tip of my tongue but I am failing to convert this to an actual name :D

It's not an ash, sycamore, prunus etc and may even be a stow away on one of my exotics as I have had a few cool plants emerge from the bark of my tree ferns

Any help appreciated

 

Is it a Rowan/Mountain Ash?

 

No defo not a Rowan...

I am thinking something along the lines of Bombax ellipticum, which would be mental for a self seeder ?

 

Walnut or Ailanthus???

 

Walnut is a good call actually as there is a walnut tree a hundred yards away and could have been a squirrel planting

 

Walnut alright, glad to see the squirrels are still doing their part

 

There's a large Walnut tree about 200 yards from our back garden and I've watched the squirrels burying walnuts in the autumn/winter all over our garden. There are also young walnut trees growing here there and everywhere around the close vacinity from ones that have obviously grown after being forgotten by the squirrels :thumb:

 

Juglans regia gets my vote too.
