Paeonia Itoh 'Bartzella' (Ships in Spring)

Intersectional Peony

Peony 'Bartzella' is an award-winning Itoh hybrid with large, 6–8 inch semi-double to fully double, golden yellow blooms delicately flushed with scarlet at the center. Standing 30–36 inches tall, it blooms in late spring to early summer, producing an abundance of flowers on strong, upright stems that do not require staking. Lightly fragrant with a lemon scent, this vigorous perennial thrives in full sun to part shade with rich, well-drained soil. Its lush, dark green foliage remains attractive throughout summer and into fall, making it ideal for borders and cut flower arrangements.

Growing and Maintenance Tips for Paeonia Itoh 'Bartzella' (Ships in Spring)

Planting: Soak roots in water for 1–2 hours before planting to rehydrate them. Plant as early in spring as the soil is workable—ideally before daytime temperatures consistently exceed 70°F. Dig a hole twice as wide as the root system. Position the crown so the pink “eyes” (buds) sit just below the soil surface: Zones 2–4: 2 inches deep, Zones 5–6: 1 inch deep, Zones 7–8: ½ inch deep.
Spacing: Space plants 3 feet apart to allow for mature spread and airflow.
Light: Full sun (6+ hours daily) is ideal. In hot climates, morning sun with light afternoon shade helps preserve blooms.
Soil: Well-drained, fertile soil with a neutral pH (6.5–7.0). Amend with compost and grit if needed to improve drainage.
Watering: Water deeply after planting and keep soil evenly moist (not soggy) through the first growing season.
Temperature & Humidity: Hardy in USDA zones 4–9. Spring-planted Itohs may take longer to establish and bloom but will thrive long-term.
Fertilization: Hold off on fertilizing until the second year. In year one, focus on root development.
Staking: Itohs have sturdy stems but may benefit from support in windy sites.
Pruning: Cut stems to the ground in late fall after frost. Unlike tree peonies, Itohs die back completely.
Propagation: Divide only if necessary, and only in fall—these long-lived plants resent disturbance.
Pest & Disease: Generally pest-free. Good air circulation helps prevent botrytis blight. Avoid overhead watering.
