Modern research on a substance from this and Paeonia alba (1,2,3,4,6-Penta-O-Galloyl-β-D-Glucopyranose, abbreviated PGG) has shown significant medicinal effects against prostate cancer, and more recently has been shown to inhibit formation of Staphalococcus aureus biofilm formation. This is apparently significant because these biofilms can form on hospital equipment, are extremely difficult to remove, and can be a source of infection.

What a wonder, exotic shrub for my garden. I would encourage everyone to try to grow one of these extremely beautiful plant in their gardens. The shape of the shrub is small, about 4 feet when mature, and the leaves combine with the wood structure to make it a regal and dignified specimen. The flowers...of course, have no rivals in the gardening world.

My favorite plants in my garden, alongside my great magnolias.

Living in the extreme weather of the Berkshires in CT, winter can be a matter of endurance. The tree peony endures the winter and usually within two years of planting even a small bare root plant, the gardener is rewarded with a bloom that looks like silk. Tree peonies last a lifetime or more. They are not hardy shrubs in the sense of a lilac's tough bark and wood stems, but more delicate. Someone walking over one, could easily destroy decades worth of growth. Ours are put on the pedestal of a raised bed. The deer have never eaten them. They need little care except weeding and proper spacing. They can be expensive, if you don't want to wait there are nurseries who can ship large plants ready to bloom the following year. Japanese tree peonies are usually grafted to a hardy root stock and c... read more

Flowers are exquisite-huge with a silk like texture. Foliage remains presentable throughout the season. Woody plant that adds structure to the garden at the 3-4 ft. height. Not bothered by disease or pests to any great degree.Long-lived-A good investment for the garden.
