  • circleLife cycle

    The Itoh peony 'Bartzella' starts its life cycle when the seed germinates in the soil, usually requiring a period of stratification (cold treatment) to break dormancy. Upon sprouting, the seedling develops its first true leaves and continues to grow, forming a root system and vegetative structures through spring and summer. As a perennial, 'Bartzella' enters a dormant phase during the autumn and winter months, where the above-ground foliage dies back, and the plant conserves energy in its root system. In the following spring, the plant emerges from dormancy, producing strong stems and lush foliage as it prepares for its flowering stage. The blooming period occurs in late spring to early summer, showcasing large, showy yellow flowers that are a distinctive characteristic of this cultivar. After flowering, the plant sets seed, and as the season progresses, it builds up reserves in its roots again for the next cycle of dormancy and growth.

      Early Spring

    • The Paeonia 'Bartzella', more commonly known as Itoh peony, is ideally propagated through division. This process is best done in the fall, when the plant is entering dormancy. To propagate by division, carefully dig up the peony plant, ensuring that you keep a generous amount of soil around the roots to reduce stress. Gently separate the root clump into sections, each with at least three to five eyes, which are the growth nodes where new stems will emerge. These sections can then be replanted at the same depth they were previously growing, ensuring that the eyes are just below the soil surface, typically around 1 to 2 inches (2.5 to 5 centimeters) deep. Water the newly planted divisions thoroughly to settle the soil around the roots and help with recovery and growth.
