Unknown Seedling ID

Since I cleared away last year's bark chippings (haven't had chance to replace it yet), I've been getting some seedlings coming up everywhere and I have no idea what they are. I assume the seeds settled on top of the chippings and when I disturbed them, they went all over the shop.


The seed casing doesn't look like anything I've grown. Any ideas what it could be?

 

Sycamore or ash is my guess.

 

My money’s on ash.

 

That looks like ash, sycamore will either still have the wing or a shorter, plumper seed.

 

I have them too: Ash tree.

Once Ash dieback has stopped, their seeds can be easily used. Every seed a tree.

 

I agree, it looks like ash. Get them out before they get any bigger. They grow tough roots remarkably quickly and while you might want one or two if you have a very large garden, you don't want a forest of them (or any at all if your garden isn't ginormous).

 

Thanks for the replies Not sure whether any of the trees in my immediate area are ash. That being said, I used to have an enormous ash tree in my back garden until it got heart rot and had to be taken down about 12/13 years ago. The only thing I remember about the shape of the seeds are that they had wings. It's more than possible that other trees down the road are also ash. I've never had a problem like this, maybe last year was windier than I remember!

@JennyJB You're not wrong about that. When these houses were built in 2001, the property developers decided not to remove the mature trees, but build around them. The ash in my garden was a good couple of storeys taller than my house and the bane of my life. The sheer volume of dead leaves in the autumn and seedlings that came up through the decking in spring, had me tearing my hair out. I was so glad when it had to come down but it took a good couple of years before the seedlings stopped popping up in unexpected places. It wasn't unusual to find one that had developed several sets of true leaves.
