Itoh peonies bring together the massive, richly colored flowers of tree peonies with the hardy, easy-care perennial habit of herbaceous peonies—a hybrid that simply outshines both parents. The real challenge isn’t finding a peony plant; it’s identifying a root with enough viable eyes to deliver those iconic, dinner-plate-sized blooms that make the entire garden stop.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time comparing bare-root specifications, studying eye counts and hardiness zone maps, and analyzing aggregated owner feedback across dozens of cultivars to pinpoint which roots actually push through the soil and produce.
This guide breaks down the concrete specs, real-eye counts, and grower-proven cultivars that separate a truly rewarding peony investment from a frustrating pile of expensive mulch. I’ve organized these picks so you can confidently select the most beautiful itoh peonies for your garden without second-guessing the root quality or bloom potential.
How To Choose The Best Most Beautiful Itoh Peonies
Itoh peonies, also known as intersectional peonies, are a deliberate cross between tree and herbaceous peonies. They produce flowers on strong, upright stems that don’t flop, bloom over a longer period, and feature foliage that stays attractive into fall. The key to success lies in selecting the right root stock from the start.
Eye Count Is Everything
The number of “eyes” (dormant buds) on a bare root directly predicts first-year performance. A 1-2 eye root often spends its first season establishing roots rather than flowering. A 3-5 eye root, by contrast, has enough stored energy to push up multiple stems and produce blooms the same spring. Always check the advertised eye count before buying—this is the single most reliable spec for predicting early show.
Hardiness Zone Matching
Itoh peonies perform best in USDA Zones 4 through 8. They require a winter chilling period to set buds, so gardeners in Zone 9 with mild winters may see reduced flowering. Conversely, in Zone 3, deep freezes can damage roots if not heavily mulched. Verify that the cultivar you choose is rated for your specific zone before ordering.
Bloom Color and Fragrance
Itoh peonies come in a narrower but more striking color range than herbaceous types, with yellows, corals, apricots, and bicolor blends being common. Many also carry a noticeable fragrance—some lightly sweet, others with a gardenia-like note. If scent matters as much as visual impact, look for reviews that specifically mention fragrance strength rather than relying on generic descriptions.

In‑Depth Reviews
1. Burpee ‘Bartzella’ Itoh Perennial Peony — 1 Bare Root 3-5 Eye Plant
The Burpee ‘Bartzella’ represents the pinnacle of Itoh breeding. This root typically ships with 3-5 eyes, giving it enough energy reserves to produce multiple stems and substantial yellow double flowers with a red center fleck in its first spring. The fragrance is present but not overpowering, fitting perfectly into a cut-flower garden where scent matters without dominating.
Owner reports consistently praise the root vigor—many note visible growth within days of planting, even when shipped internationally or delayed in customs. The few complaints center on missing items in multi-unit orders, not on root quality itself. Burpee’s organic tag and detailed soaking instructions give beginners a clear path to success.
At this eye count and cultivar reputation, this root is the strongest bet for anyone who wants a guaranteed showstopper bloom without waiting two seasons. The plant is naturally compact at around 30 inches tall, so staking is rarely needed—a significant advantage over taller, floppy herbaceous peonies.
What works
- High eye count (3-5) ensures strong first-year growth
- True Itoh genetics—strong stems, no staking needed
- Fragrant double yellow blooms with red center accents
What doesn’t
- Occasional shipping delays due to customs inspections
- Single root only; multi-unit orders may have fulfillment issues
2. Gardenia Double White Peony — Live Plant Bare Root
The Gardenia Double White Peony stands apart for one specific reason: it carries a true gardenia-like fragrance distinct from the typical sweet peony scent. Multiple verified buyers specifically call out the aromatic surprise, describing it as “amazing” and “perfect.” For anyone who prioritizes olfactory impact alongside visual beauty, this root delivers a rare combination.
The root itself ships as a bare-root plant with 3-5 eyes and pure white double blooms that reach about 3 feet tall. The mixed feedback on survival rates—some buyers report dead roots while others get vigorous growth—suggests the shipping and handling conditions matter heavily with this seller. Soaking the root overnight in warm water before planting, as Burpee recommends for its Bartzella, seems equally applicable here.
If you score a healthy root, the payoff is exceptional: white blooms that smell like gardenias. That’s a combination you simply won’t find in standard herbaceous peonies. Treat it as a premium gamble with a high ceiling rather than a guaranteed hit, and you’ll appreciate the outcome more.
What works
- Unique gardenia fragrance sets it apart from all other peonies
- Pure white double blooms add elegant contrast to gardens
- Attracts pollinators without sacrificing scent profile
What doesn’t
- Inconsistent root viability—some arrive dead or never sprout
- Higher price point per single root compared to mid-range options
3. Garden State Bulb Bartzella Yellow Itoh Peony Flower Bulbs — Bag of 2
Garden State Bulb offers what is arguably the best price-per-root ratio for a named Itoh cultivar. The bag of 2 provides two separate 3/5-eye Bartzella roots—the same prized yellow double bloomer that Burpee sells as a single root for nearly double the total cost. The roots arrive packed in temperature-controlled conditions, and buyer feedback consistently describes them as “healthy” and “very active,” sprouting within a week of planting.
The 156-year limited manufacturer warranty sounds impressive on paper, but the fine print clarifies it’s a one-year growth and flowering guarantee that requires proof of purchase and returning the plant. In practice, most owners report no need to invoke it because the roots simply grow. The heirloom material tag means this is a proven, non-patented cultivar that has produced reliably for decades.
For gardeners planting a new bed or wanting to ensure at least one survivor, the twin-pack approach reduces risk. If one root underperforms, the second likely will not. The 3-foot height and full-sun-to-partial-shade tolerance make it flexible for most garden layouts.
What works
- Two roots per pack at a price that undercuts single-root competition
- Consistent germination reports—sprouts seen within 5-7 days
- Temperature-controlled shipping reduces transit damage
What doesn’t
- Warranty process requires returning product and proof of purchase
- May not bloom in first season despite strong foliage growth
4. Sarah Bernhardt Double Pink Peony — Large 3-5 Eyes Bare Root
The Sarah Bernhardt is not technically an Itoh peony—it’s a classic herbaceous double pink peony—but its 3-5 eye count, heirloom status, and legendary fragrance make it a worthy inclusion for any garden seeking beautiful blooms. Marde Ross & Company has been a licensed California nursery for 28 years, and the bare roots they ship are consistently described as “easy to plant” by owners who saw blooms the same spring.
The division on this product is sharp: roughly half the reviews rave about immediate growth and stunning pink flowers, while the other half report small roots with little green showing. The 4.8-ounce weight suggests these are not massive roots, so careful pre-planting soaking and proper soil depth (top of root 2 inches below soil line) strongly influence outcomes. The “grows well in all climates” claim is optimistic—Zone 3 winters will require extra mulch.
If you want the most recognizable peony name in the world for cut-flower arrangements, this is the one. Just pair it with a strong Itoh cultivar if you want the hybrid’s longer bloom window and sturdier stems.
What works
- Very fragrant double pink blooms—a cut-flower favorite
- Longstanding nursery reputation (28 years in business)
- Established heirloom variety with predictable growth pattern
What doesn’t
- Variable root size—some shipments are quite small
- Herbaceous type, not a true Itoh; stems may need staking
5. Mixed Peony Jumbo Pack — 6 Paeonia Large Roots (White, Pink, Red)
The Mixed Peony Jumbo Pack from Willard & May offers the lowest per-root cost in this lineup, shipping six 2/3-eye roots in white, pink, and red. The appeal is obvious: you get instant variety across three colors for a single purchase. The roots are labeled as organic material and expected to bloom in early summer across Zones 3 to 8.
The trade-off is consistency. Multiple verified reviews report receiving 5 roots instead of 6, roots arriving with sprouts already broken from handling, and zero color identification—you plant blind and discover colors only after blooming. The 2/3-eye count also means most roots will focus on root establishment in year one rather than flowering. A few buyers report no growth at all despite following instructions.
For budget-conscious gardeners willing to accept a lottery approach—some roots thrive, some don’t—this pack fills a large bed affordably. But if you want predictable color, verified eye count, and named cultivars, the Garden State Bulb twin-pack provides better reliability per dollar spent.
What works
- Six roots at a very low per-root cost—fills large spaces
- Mixed colors (white, pink, red) create natural variety
- Many owners report strong, vigorous root systems
What doesn’t
- No color identification on individual roots—blind planting
- Frequent missing items (5 of 6 received) and broken sprouts
Hardware & Specs Guide
Eye Count
The eye count determines how many stems a bare root can produce in its first year. A 3-5 eye root typically yields 3-5 stems, each capable of holding one to three flower buds. Roots with 1-2 eyes will spend most of their energy on root expansion and may not bloom until year two. Always select 3-5 eye roots for immediate visual payoff.
Hardiness Zone
Itoh peonies are reliably perennial in USDA Zones 4 through 8, though some cultivars stretch to Zone 3 with heavy winter mulching or Zone 9 if given afternoon shade. The zone rating matters because peonies require a cold dormancy period (vernalization) to trigger bud formation. Check your zone before ordering to avoid disappointment.
