Thanks to Husband I now know the difference between Ash and Mountain Ash (or Rowan). At least I do in spring when the Mountain Ash has white flowers
And the difference between Horse and Sweet Chestnut. Horse has white flowers and Sweet has pink. The leaves also differ enough to be able to differentiate in the absence of flowers.
I will soon be a fully fledged Tree Woman.
The fact that Husband will suddenly point at a tree and say, 'What's that?' is doing wonders for my knowledge but playing havoc with my nerves as I stutter, 'Ash? No, sycamore? No, beech? Hazel? Birch?'
I may have a while to go to reach Expert status ...
