There’s something quietly extraordinary about watching a Sonoma Ye Do Itoh Peony open its enormous blooms in late spring — petals layered like silk, colors deepening at the center, fragrance drifting across a warm afternoon garden.
This intersectional peony crosses the dramatic flower power of tree peonies with the reliable, cold-hardy nature of herbaceous types. The result: spectacular dinner-plate blooms on naturally sturdy stems that rarely need staking, making it a genuine standout in borders and cutting gardens alike.
Grow it in full sun to part sun, in rich, well-drained soil with regular moisture during active growth. It reaches 24–36 inches tall and 30–48 inches wide, thriving in USDA Zones 3–8. After frost, cut stems to the ground and let it rest.
Sonoma Ye Do ships bare root in fall — the window when peonies establish best and bloom most reliably come spring.
🍂 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.
