There’s something quietly dramatic about a bloom that stops people mid-step — and Crimson Crown (Hong Guan Yin Xian) does exactly that. Unfurling in deep, jewel-toned layers, this Rockii tree peony (*Paeonia rockii*) produces flowers up to 7.9 inches across, with that distinctive dark flare at the petal base that makes Rockii varieties so prized among peony enthusiasts.
You’ll receive a dormant bareroot plant, 2–3 years old with 2–3 branches. It arrives 10–25 inches tall and will reach about 3 feet with new spring growth. Plant it 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. In colder climates, a light layer of mulch after planting goes a long way. Hardy in USDA zones 4–9, this deciduous beauty is built for Pacific Northwest winters.
Fall is the ideal planting window. Roots settle into warm soil before the cold arrives, and spring growth emerges strong and bloom-ready. 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.
