The unique foliage of Paeonia suffruticosa is leathery and gray-green, forming a mound of foliage which generally turns yellow in fall. The plant is fragrant with a sweet, pleasant scent and prefers semi-shade and regular water, often reaching maturity in 4-5 years if healthy.

Pruning of the Paeonia suffruticosa can begin in late fall or early winter, although flowering may be reduced in the first few years. When pruning, the basal growth should remain untouched and any dead or diseased material should be removed.

Care of the Paeonia suffruticosa is dependent on your climate. It is hardy to USDA zones 5-9. In warmer regions, the plant is quite hardy and can survive with minimal water and protection, while in colder climates it will require more attention. In cold areas it is best to grow the plant in a pot and bring it indoors during the winter. potted plants should be placed in a bright, cool spot and watered regularly. If possible, the pot should be positioned so that it is sheltered from extreme conditions like wind and sun. The soil should also be well-draining, as the roots of the Paeonia suffruticosa can rot in overly damp soil.

Overall, Paeonia suffruticosa is an attractive and rewarding plant to grow, offering a wide range of flower forms and fragrances. With regular pruning and plenty of sun and water, it can provide many years of enjoyment for your garden.
