Intersectional Peony

Peony 'Scarlet Heaven' is a striking Itoh hybrid with large, 7–9 inch single-form, deep scarlet-red blooms surrounding bright golden-yellow centers. Standing 25–29 inches tall, its lightly fragrant flowers appear in late spring. Thriving in full sun with well-drained soil, this robust perennial does not require staking.

Growing and Maintenance Tips for Paeonia Itoh 'Scarlet Heaven' (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.
