Safety

People: The plant is considered mildly toxic if ingested in large amounts.
Pets: Peonies can cause mild to moderate digestive upset if ingested by cats or dogs.
Children: Keep children away from the roots as they are the most concentrated source of toxins.
Contact allergens: The sap may cause mild skin irritation in sensitive individuals.
Airborne allergens: The heavy pollen can trigger hay fever during the peak bloom period.
Edibility: While some petals are used in tea, the plant contains paeonol which can cause digestive distress if consumed in quantity.

Growing it

Propagation: division, seed
When to plant: fall, early spring
Overwintering: Cut the foliage back to the ground after it yellows in autumn. Apply a light layer of mulch if you live in a very cold region to protect the crown.
In containers: Peonies grow best in the ground, but can be kept in very large pots for a few years.

Division

1. Dig up the clump in early autumn.
2. Wash soil away to see the eyes.
3. Cut the root mass into sections with at least 3 eyes each.
4. Replant with eyes no more than 5cm deep.

Plant peonies near spring bulbs to hide the fading foliage of the bulbs as the peonies grow.
