Fruit tree & flowers mixed

[new gardener 1052]

Good evening all... Has anyone tried and had success with growing a fruit tree in a container & planted various flowers in the container too?

Was a idea I had might have a go over the weekend, I would like to hear your experiences
I was thinking of a patio james grieves apple not sure what other flowers to put into the container.

I think the flowers would take all of the nutrients away from the tree.
