These are the flowers and buds of the previously described tree, unfortunately I cannot say which type of tree this is.....where is the botanist who can help me.

Hello Andreas,
I am not a botanist, but I would say that this is a young apple tree.
Greetings from Aachen,

Hello Mario, I was absolutely not sure whether it was an apple tree or a pear tree. I can already identify quite a few trees by their bark. But the trunk was completely smooth, and before I wrote something nonsensical here, I thought I’d ask if anyone has an idea or clue. If we were wrong, it doesn’t matter... thanks for your effort, Mario. Andreas
