Few plants stop a garden in its tracks the way Crimson Dragon does. Known in Chinese as Hong Hai Qing Long, this Rockii Tree Peony unfurls blooms with the kind of depth and drama that makes you lean in closer — deep crimson petals with that signature dark flare at the base, carried on woody stems that grow more beautiful with each passing year.
You’ll receive a dormant bareroot plant, 2–3 years old with 2–3 branches, shipped 10–25 inches tall. Come spring, expect new growth to reach around 3 feet. Plant in partial shade with fertile, well-drained soil that leans neutral to slightly alkaline. Water moderately during establishment — consistently moist, never soggy. Hardy in USDA zones 4–9, it’s remarkably tough; a light layer of mulch protects roots in colder winters.
Rockii tree peonies are long-lived, cold-hardy flowering shrubs prized by collectors and heirloom garden enthusiasts alike.
Crimson Dragon ships fall only — September through November — when dormancy ensures the healthiest root establishment. 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.
