Peonies Bloom

Types:

There are three types of peonies: herbaceous (bush), tree and Itoh (intersectional). Compare them in detail here: Types of Peonies.

Height/Spread:

Herbaceous and Itoh varieties grow 1 to 3 feet tall, with a similar spread, while a mature tree peony can reach 4 to 7 feet tall and 4 to 5 feet wide.

Exposure:

Most peony plants are sun-lovers. However, tree peonies prefer light shade during the heat of midday, which encourages the blossoms to last 10 to 14 days, rather than fading quickly (two to three days) in full sun. In China, parasols are enlisted to protect the delicate flowers from sun.

Bloom Time:

In most locations, flowers will bloom in April, May or June. Expect tree peonies to bloom first (around Mother’s Day), followed by herbaceous varieties (around Memorial Day) and then the intersectionals. Include all three types in the garden to enjoy blooms for up to seven weeks.

Flower color:

Colors range from white, pink and red to coral, maroon and yellow. Many peony flowers change color as they open, so make sure to check them daily to appreciate these differences.

Fragrance:

Many peony flowers are fragrant. Scents can differ—some are scented sweetly, some have enticing citrus smells, and some are described as slightly spicy.

Pests and diseases:

Fortunately, they are deer and rabbit resistant. Unfortunately, they are susceptible to botrytis blight, a fungus that can cause young shoots to rot, unsightly spots on leaves, and prevent flower buds from developing. Good air circulation around your plants will help prevent fungal diseases. Learn more about issues that can arise in the Missouri Botanical Garden’s guide to peony problems.
