There’s something quietly theatrical about a tree peony that opens blooms the size of a salad plate — and Snowfield Glow (Xue Yuan Yu Hui) delivers exactly that. Each flower stretches to 17 cm across, its petals carrying that luminous, silk-like quality that makes Rockii tree peonies (*Paeonia rockii*) so coveted among serious gardeners.
You’ll receive a dormant bareroot plant, 2–3 years old with 2–3 established branches, shipped at 10–25 inches tall. By its first full spring, expect plants to reach roughly 3 feet. Hardy in USDA zones 4–9, this deciduous beauty handles cold remarkably well — just mulch lightly in harsher winters and ensure soil never sits waterlogged. Give it partial shade, fertile and well-drained soil with a neutral to slightly alkaline pH, and moderate, consistent moisture during establishment.
Rockii tree peonies ship dormant and bareroot each fall (September–November) — the only window that sets roots up for reliable, long-term bloom. 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.
