There’s something quietly magnificent about watching a Rockii tree peony emerge from late-winter dormancy — bare stems suddenly unfurling into one of the most dramatic blooms a garden can offer. The Radiant Rose, known in Chinese as Mei Gui Sa Jin, opens to flowers nearly 7 inches across, their silky petals catching light in a way that stops you mid-step.
You’ll receive a 2–3 year old bareroot plant with 2–3 established branches, shipped dormant in fall — the only window that gives roots time to settle into warm soil before winter. By spring, expect growth reaching around 3 feet tall.
Plant in fertile, well-drained soil with a neutral to slightly alkaline pH. Radiant Rose thrives in partial shade, prefers moderate, even moisture during establishment, and is reliably cold-hardy in USDA zones 4–9. A light layer of mulch protects roots in colder climates; avoid waterlogged soil through winter.
🍂 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.
