There’s something quietly theatrical about a bloom that stops you mid-step — and Imperial Pavilion (Zi Gong Ge) delivers exactly that. This Rockii tree peony opens flowers nearly 8 inches across, each petal carrying the painterly depth and elegance that makes Rockii varieties so sought after by serious gardeners.
You’ll receive a dormant bareroot plant, 2–3 years old with 2–3 established branches, arriving 10–25 inches tall. Come spring, expect growth reaching around 3 feet. Plant in fertile, well-drained soil with a neutral to slightly alkaline pH, in a spot with partial shade. Water moderately during establishment — evenly moist, never waterlogged, especially through winter. Hardy in USDA zones 4–9, a light mulch in colder climates is all the winter protection it needs.
Imperial Pavilion ships dormant and bareroot in fall (September–November) — the only window Fall planting lets roots anchor before winter, setting up strong, reliable bloom cycles for years ahead. Local pickup available upon request.
🍂 Shipping & planting window
Peonies ship in fall (September–November) when fully dormant and bare root.
Fall planting gives roots a full season to establish in warm soil before winter. Cold stratification triggers strong, healthy spring growth and reliable bloom production. Spring-shipped peonies experience root damage during active growth, transplant shock during their bloom cycle, and often lose an entire growing season.
