Possibly Crataegus laciniata.
You are very close Jeanne. The clue is it has no thorns. Try again, I am dying for someone to win!
Oh in that case it must be crataegus laevigata, the flowers are very similar on both.
Still close but that one has thorns too! Look up thornless Hawthorn.
It might be the Crataegus crus-galli var. inermis
The flowers look similar
The leaves are not the same Hermann. The shape and colour are different but I agree, the flowers are very similar.
