Peony is a perennial shrub-looking plant in the Paeoniaceae botanical family, genus Paeonia. It is frequently cultivated in gardens, courtyards, parks or other green spaces, its lush and pleasantly fragrant flowers being much loved. It blooms annually, in early spring. The large, intense green leaves are also decorative. Additionally, peony is widely grown for its flowers, which are used in various floral arrangements and bouquets.

There are numerous herbaceous species of peonies, as well as several woody species (shrubs). Most often we find the following herbaceous species:

Paeonia lactiflora (Chinese peony)

Species native to East Asia, widespread in the natural area both at low altitudes and in the mountains and Alps. It can have heights of approx. 1 m. The leaves are lobed, large, up to 16 cm long and up to 6 cm wide. One stem has 3-4 terminal flowers, each with 9-13 white or pink petals.

Varieties:
  • Paeonia peregrina var. romanica (Romanian peony) – endemic species, found in the spontaneous flora of Dobrogea, Muntenia and Moldova, with red flowers.
Paeonia tenuifolia (fernleaf peony)

Species native to southeastern Europe, which grows in the spontaneous flora at low altitudes. It has stems with heights between 20 and 60 cm, lobed leaves and flowers with 6-8 red petals.

Environmental conditions

Light. The peony prefers sunny places, but also tolerates partial shade. In the shade it grows weakly and does not bloom, sometimes it even dries.

Temperature. It is a resistant species in terms of climatic conditions. It can withstand both the negative temperatures during the winter and the very high temperatures during the summer.

Soil. In the case of peony, it is very important that the soil is well drained, because it is a species sensitive to excessive water or water stagnation in the soil. At the same time, the soil must have the capacity to retain the water. It vegetates well on fertile soils, with low alkaline, neutral or slightly acidic pH.

Care

Water. During the vegetative growth period, peonies are relatively resistant to the lack of water in the soil, but occasional watering is recommended during the dry period. More important it is to ensure a sufficient amount of water in early autumn, when the flower buds are formed for the following year. During irrigation, the water should not touch the leaves, but only be done at the ground level.

Fertilization. For vigorous growth and abundant flowering, it is recommended to apply specific fertilizers during the vegetative growth period.

Pruning. The withered stems and leaves can be removed at any time of the year, the cutting being done above a viable bud (internode) or at the soil surface. For bouquets or floral arrangements, floral stems can be cut from various heights, using a sharp cutting tool (scissors or knife). It is recommended to avoid cutting the floral stems in the first 2-3 years after planting.

Planting. The recommended period for planting peonies is from August to October, before the soil freezes. Peony is a very vigorous plant, but sensitive to transplanting, so it is recommended to ensure the necessary space at maturity from the beginning: 0.5-1 sqm / plant.

Diseases and pests. The health of the peonies can be affected by the attack of various insects (mites, thrips, aphids, larvae of moths and butterflies, etc.) or by the presence of pathogens that cause diseases (rot, stains, powdery mildew, etc.). It is recommended to carry out preventive and control treatments with specific insecticides and fungicides.

Additionally:
  • Once planted, peonies bloom annually, without requiring special care.
  • Peonies need low temperatures in winter. Otherwise, the plants vegetate poorly and do not bloom.
  • Parts of peonies are used in the pharmaceutical industry (especially the roots).
  • Peony is considered toxic, avoid consuming plant parts!
  • The mountain peony (rhododendron) is a woody, shrubby species, completely different from garden peonies, belonging to the botanical family Ericaceae, genus Rhododendron.
