There’s something almost theatrical about the moment Sugar Surprise opens — those enormous 7-inch blooms unfurl in shades that shift and layer like a watercolor painting, earning this Rockii tree peony its playful name. Run your fingers along the deeply lobed foliage and you’ll understand why gardeners seek these out for decades of garden drama.
Plant your bareroot specimen in fertile, well-drained soil with a neutral to slightly alkaline pH, in a spot with partial shade — dappled morning light suits it beautifully. Water moderately during establishment, keeping the soil evenly moist but never soggy, especially in winter when waterlogged conditions can cause real harm. A light layer of mulch protects roots in colder climates. Hardy in USDA zones 4–9, this deciduous shrub arrives dormant at 10–25 inches with 2–3 branches, reaching roughly 3 feet by its first spring flush.
Ships bare root in fall (September–November) — the proven window for strong 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.
