Peony ‘Amabilis’ is a cherished garden perennial, known for its elegant, fragrant blooms. Its classic appeal and robust nature make it a popular choice for creating a visually striking display in various garden styles.
Key Characteristics of Peony Amabilis
Peony ‘Amabilis’ is distinguished by its large, double flowers, presenting in shades of fuchsia-pink, sometimes with paler pink petaloids towards the center. These blooms can reach a diameter of up to 5-6 inches (12-16 cm) and emit a sweet fragrance.
This herbaceous peony has an erect, clump-forming growth habit. It blooms in mid to late spring, from May to June depending on the horticultural zone. The plant reaches a height of 25-36 inches (60-90 cm) and can spread about 20-30 inches (50-70 cm). Its dark green foliage provides a lush backdrop for the vibrant blossoms.
Planting and Care for Peony Amabilis
Site Selection and Sunlight
Successful growth and abundant flowering of Peony ‘Amabilis’ require the right location. Peonies thrive in full sun, requiring at least six hours of direct sunlight daily. While they tolerate some partial shade, especially in hotter climates where afternoon shade is beneficial, ample sunlight promotes vigorous growth and better flower production. Good air circulation is important to prevent diseases; space plants 2-4 feet apart to allow for mature growth.
Soil Requirements
Peony ‘Amabilis’ prefers well-drained soil rich in nutrients. A loamy or sandy loam soil type is suitable, with a neutral to slightly alkaline pH. Peonies do not tolerate waterlogged conditions, which leads to root rot. Improving heavy clay soils with compost and grit enhances drainage. Work the soil to a depth of 18 inches to create a loose, well-conditioned bed for the roots.
Watering Needs
Consistent moisture is important for ‘Amabilis’ peonies, especially during establishment and dry periods. Newly planted peonies require regular watering. Established plants need about 1 inch of water per week, particularly if rainfall is low. Water deeply every 10 to 14 days for mature plants, ensuring the soil is moist to the second knuckle of a finger.
Water at the base of the plant to avoid wetting foliage, as this encourages fungal diseases. Applying organic mulch helps retain soil moisture and regulate temperature.
Fertilization
Peonies do not require heavy fertilization, especially if planted in rich, well-amended soil. Excessive nitrogen promotes lush foliage at the expense of flowers. If the soil is poor or plants appear to be struggling, apply a balanced, slow-release fertilizer in early spring as new growth emerges or after blooming. Avoid applying soil amendments, such as manure, directly to the peony crown area after planting, as this causes crown rot.
Pruning and Support
Minimal pruning is needed for Peony ‘Amabilis’. Deadheading, which involves removing spent flowers, helps tidy the plant and redirect energy. Do not cut back the foliage prematurely, as the leaves gather energy for the following year’s blooms. The foliage should remain on the plant until it naturally yellows or dies back in the fall, after the first frost; then it can be cut to the ground.
Due to their large, heavy blooms, ‘Amabilis’ peonies benefit from support to prevent stems from flopping, especially after rain or in windy conditions. Peony rings or staking provide support.
Addressing Common Peony Issues
Peonies are robust plants, but they can encounter issues affecting their health and blooming. A frequent concern is the lack of blooms, which stems from several factors. Improper planting depth is a primary cause; planting too deeply inhibits flower production, while planting too shallowly exposes the “eyes” to freezing or drying. Peonies require winter cold to set buds, so insufficient chilling in warmer climates prevents flowering.
Insufficient sunlight is another common reason for non-flowering, as peonies need at least six hours of direct sun for optimal blooming. Newly planted peonies can take a few years to establish and bloom. Over-fertilization with nitrogen leads to abundant foliage but few flowers. Peonies also dislike being moved, and transplanting delays blooming for several years.
Fungal diseases can affect peonies, particularly in cool, moist conditions. Botrytis blight, also known as gray mold or peony wilt, causes brown or black spots on leaves and stems, wilting, and rotting of buds. Powdery mildew appears as a white, dusty coating on leaves. Good air circulation, proper spacing, and promptly removing and disposing of infected plant material are effective preventative measures.
For pests, ants are seen on peony buds, attracted to a sugary sap, but they are harmless to the plant. Other pests like aphids are managed with a strong spray of water or neem oil.
