Tree Peony 'High Noon' with 2 Kinds of Foliage - 3/27
Have you ever noticed your tree peony have 2 kinds of foliage? If so, you really need to remove one of them. Which one? The one that's not growing from the woody stems. You see, tree peonies are mostly grafted plants, meaning they take a branch from a very large and mature tree peony and graft or meld it to the root of an herbaceous peony. Usually those herbaceous peony roots are grown from some random no-good herbaceous peony seed. They just grow lots of those herbaceous peony seeds to get a large crop of very young (and hopefully vigorous) peony roots on which to graft their tree peony stems.

Still not sure which foliage to remove? Take a look at the photos. The herbaceous peony foliage is very shiny and slick. The tree peony foliage is more dull and softer. Also take a look at the leaves on each branch of the foliage. The herbaceous peony leaves are more pointed and usually come to a defined tip. The tree peony leaves are more spreading and usually have small cuts in them. Hopefully you've been able to identify which foliage is herbaceous and which foliage is tree peony now. So now all you need to do is cut the herbaceous peony stem or stems all the way down, right at or just below the soil surface.

If you're curious to see just what kind of flower that herbaceous peony nurse root might make, I have saved you the trouble. I decided to let the herbaceous nurse root bloom this year since it had an obvious bud on it that looked like it would mature. As you can see the flower is nothing to speak of at all. It is very small, very tiny, with very short petals, kind of sad actually. If you think about it, no one is going to graft a beautiful herbaceous peony (and valuable - that they could otherwise sell) to the bottom of a tree peony. So it is really best to remove this herbaceous peony foliage from your tree peony as soon as you notice it, so that any energy stored in that herbaceous root is not lost to the herbaceous foliage, flower, or seed development. You really want that herbaceous nurse root to use all of its energy to help the tree peony grow and become established. Happy Growing!!
