The peony is a perennial flower with the scientific name Paeonia lactiflora. The peony has large, fragrant flowers that come in nearly every color except blue. Peonies can grow up to 4 feet tall, and even staking for support. If you want to add a few peony plants to your garden, you will want to plant them in late fall or early spring.
Choose a spot in your garden for your peony plant. According to the Garden Helper, you need to dig a hole that is 18 inches deep, and 18 inches in diameter.
Place 4 inches of organic material in the bottom of the hole you just made. This can be anything from horse manure to pine bark.
Add a 10-6-4 (nitrogen-phosphorus-potassium) fertilizer to the 4 inches of organic materials and mix them together.
Mix together some garden soil and compost and then add 7 inches of it to the hole.
Examine the peony for two eyes. These are small, red buds. They must be facing upward. Place the peony in the hole and cover it up the rest of the way with soil.
Water your peony until the soil is moist.
