Questions tagged [peonies]

Plants, genus Paeonia, grown for their flowers.

Peony (or paeony) are plants of genus Paeonia, the only genus in the Paeoniaceae family. There are between 25 and 40 species, although species definitions are not distinct.

Peonies are native to Asia, southern Europe, and western North America. Most are herbaceous perennials although some resemble small trees. Leaves are compound and deeply lobed. They are grown for their large, usually fragrant flowers. Flower colors range from red to pink to white to yellow, and are typically in late spring or early summer.

Herbaceous peonies are propagated by root division or seed. Tree peonies can also be divided by grafting and cuttings.

Is it possible to keep peonies standing upright?

My peonies quickly drooped over and became quite unattractive. Is there a way to keep them upright? I'm not thrilled about the idea of putting in stakes for each plant if that's my only option.

What is this plant and how do I care for it?

It's very fragrant. As you can hopefully see in the second photo, there are no thorns. The plant itself is looking a little out of control, like it could use some pruning. I'm just not sure how or when to go about it.

Does anyone know what this peony is suffering from? The leaves aren't wilted, they are rigid and rubbery and have twisted themselves into tight, deformed shapes. The neighbouring peonies appear healthy and in fact the same peony was healthy last…
