Which peony do you have many of the tree peonies developed by a Prof Saunders either hide the flowers or have them just in the leaves. It is a matter of taste and that was his taste. If it is one of his you may want to find a site that you can look directly eye level at the foliage such as along an entry way or some garage entrances have a raised area.

I have the same yellow peony covered with massive double bloom most facing down and hidden in the leaves. These I often cut and challenge my wife to make a suitable arrangement of them. For viewing in the garden I have not found a way. Al

The one you have is probably Chromatella. I had one that bloomed in the foliage like that and I dug it out and gave it away. The flowers were so big and heavy they nearly touched the ground.
