This is a good time to have a tree peony discussion among the members growing them. I am sure there are others who would like to grow them but, like myself, have no idea of how to go about it. Usually, mixing all the different types of peonies together results in important tips and demonstrations being lost in the clutter. I love the pictures in catalogs featuring tree peonies because they are different from the regular peonies. Same thing applies to other peonies such as fern leaf and species type.
