You’re looking at something rare — a Rockii tree peony with centuries of cultivation history behind it. Rose Diamond (Hong Guan Yu Zhu) arrives as a dormant bareroot plant, 2–3 years old with 2–3 sturdy branches, and that quiet, bare-root stillness is exactly what makes fall planting so powerful. Cold stratification signals the roots to settle in and prepare for vigorous spring awakening.
Tuck it into fertile, well-drained soil with a neutral to slightly alkaline pH, in a spot with partial shade — the kind of dappled morning light that protects those blooms without dimming them. Water moderately, keeping soil evenly moist but never waterlogged, especially through winter. Hardy in USDA zones 4–9, this deciduous woody peony appreciates a light mulch layer in colder gardens. Expect plants to reach roughly 3 feet tall by their first full growing season.
Ships September through November only, bareroot and dormant. 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.
