For those interested in unusual planted trees, here is one at Centre Vale park Todmorden.

It is about 25 years old and was sent from the nursery as a Red Oak.
I had walked past it all that time until about 3 years ago I realised it was actually a Hungarian Oak (Quercus frainetto).

My photo is of a dead leaf but shows it to be much larger than a native Oak leaf and has deep square shaped lobes, which are divided into sub-lobes.
The tree has not yet produced any acorns.

The native range is the Balkans and the tree was introduced to Britain by Charles Lawson, an Edinburgh nurseryman, about 1835.

A very unusual characteristic is the lovely sweet balsam smell from the autumn leaves which lasts for months if they are put in a bowl as a pot-pourri (the living leaves on the tree don’t smell).
This attribute is not mentioned in any account I have come across and may be a good way to confirm the identity of the tree.

The books say Hungarian Oak is planted in parks and large gardens but I have never seen another one, except in the arboretum at Thorpe Perrow in North York
—incidentally this also had the balsam smell on its dead leaves.

I would be interested to know if anyone knows of another growing in Calderdale.
If not, visit Tod Park and tick it off your list.
