Peony, also known as the "King of Flowers" or "Luoyang Flower," is a deciduous shrub belonging to the Ranunculaceae family. It typically grows to a height of 1-2 meters, with some varieties reaching up to 3 meters. The plant has thick, fleshy roots and multiple branches. Its leaves are broad, compound, and usually have two to three pinnate divisions, with long petioles and 3 to 5 lobes at the tip. The flowers appear singly at the top of the annual shoots, with diameters ranging from 15 to 30 centimeters. They come in a wide range of colors, including deep reds, pinks, yellows, whites, greens, purples, and even blues. The blooms can be single or double, and they generally flower between April and May.
As one of China's most famous flowers, peony is celebrated for its vibrant colors, rich fragrance, and elegant appearance. It has earned the titles of "The National Flower" and "The King of Flowers." In gardens, it can be planted alone, in groups, or as part of larger arrangements, making it a versatile and popular choice.
Propagation of peony can be done through seeds, cuttings, grafting, or layering. However, the most common and effective method is using cuttings. Since peonies are bushy shrubs, they are well-suited for this technique. The best time for cutting propagation is from late September to mid-October. During this period, the roots heal more easily, and new roots begin to grow quickly.
If the cuttings are done too late, the root wounds may not heal properly, and no new roots will form that year. This can lead to poor growth in the following spring, as the plant requires a lot of water and nutrients for flowering. Without sufficient root development, the plant may wilt and die.
On the other hand, doing cuttings too early, especially in late summer, can cause premature growth of the top buds, often referred to as "autumn shoots." This consumes valuable nutrients and negatively affects the plant’s growth and flowering in the next season. If cuttings are done in spring, the plant starts growing rapidly, which demands a lot of water and nutrients. But if the root system hasn't healed yet, the plant may suffer from malnutrition, fail to bloom, and become weaker, impacting future flowering.
To ensure successful propagation, choose a strong, four- to five-year-old plant as the mother plant. Carefully dig up the entire clump, gently remove excess soil, and let the roots dry in a cool place for 2–3 days until they are slightly softened. Then, divide the clump by hand or with a clean knife into several sections, each containing 3–4 shoots and 2–3 healthy roots. After dividing, apply charcoal powder to the cut surfaces to prevent infection before planting.
When planting, maintain the same depth as the original planting level. Planting too deep can cause yellowing leaves and root rot, while planting too shallow exposes the roots and stem, weakening the plant’s ability to withstand drought and cold. After planting, water thoroughly and provide shade if needed. In colder northern regions of China, it’s advisable to protect the plants during winter by covering the root neck or packing straw around them to prevent frost damage.
