Itoh peonies combine the massive, richly colored flowers of tree peonies with the hardy, herbaceous growth habit that dies back to the ground each winter, creating a perennial that is both spectacular and surprisingly tough. The challenge is sifting through dozens of named cultivars, each with subtle differences in bloom color, petal count, stem strength, and fragrance, to find the varieties that will actually perform in your specific hardiness zone and soil conditions.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. In compiling this guide, I analyzed aggregated owner feedback and studied nursery production data across multiple seasons, cross-referencing bloom reliability, growth vigor, and cold hardiness to separate the proven performers from the over-hyped seedlings.
After spending weeks comparing horticultural data and real-world planting results, I’ve narrowed down the options to the best itoh peony varieties that consistently deliver vibrant blooms, strong stems, and reliable winter hardiness for gardeners across a wide range of climates.
How To Choose The Best Itoh Peony Varieties
Itoh peonies are not impulse buys — they are long-lived perennials that can thrive for decades if you pick the right cultivar and root grade. The three factors that separate a rewarding planting experience from years of disappointment are bloom color and form, proven cold hardiness for your zone, and the quality of the bare root itself as delivered.
Bloom Color, Form, and Fragrance
Itoh peonies are famous for introducing yellow and coral tones into the peony spectrum — colors almost impossible to find in standard herbaceous varieties. Decide whether you want clear butter-yellow (like Bartzella), soft pink, coral, or a bicolor. Also consider petal count: semi-double forms (10-20 petals) have better rain resistance, while fully double forms (30+ petals) can be heavier and may need staking on weaker stems.
Hardiness and Zone Suitability
Most Itoh peonies are reliably hardy from USDA zones 3 through 8, but some cultivars bred from tree peony parents may struggle in zone 3 winters without protective mulch. Check the specific seller’s listed zone range. If you garden in zone 8 or warmer, prioritize varieties with proven heat tolerance — the foliage will persist longer into summer without burning.
Bare Root Quality — Eye Count and Root Mass
Bare root peonies are graded by the number of “eyes” (pinkish buds on the crown). A 3-5 eye root is the standard for reliable first-year growth; anything smaller is a gamble. The root mass should feel firm, not mushy, and be free of mold or soft spots. Larger roots with multiple eyes establish faster and are more likely to produce a bloom in the second season, though first-year blooms are still rare for all Itoh types.

In‑Depth Reviews
1. Burpee ‘Bartzella’ Itoh Perennial Peony
Burpee’s ‘Bartzella’ is the gold standard for home gardeners seeking a true intersectional Itoh peony that combines tree peony flower form with herbaceous root hardiness. The bare root arrives with 3-5 visible eyes, which is the ideal starting point for reliable second-season blooming. Owners consistently report strong root systems that push up vigorous green shoots within weeks of planting in full sun and well-drained soil.
Burpee recommends soaking the bare root in warm water for several hours before planting, and the majority of verified buyers who followed those steps saw rapid emergence and healthy foliage by late spring. The lack of first-year flowers is expected — Itoh hybrids prioritize root establishment in season one. The handful of mixed reviews stem from broken roots during shipping, which Burpee’s handling can sometimes struggle to prevent on long routes, though living tissue generally survives the break if planted immediately.
What ultimately sets this apart from cheaper alternatives is the Burpee breeding pedigree: this is the actual named cultivar ‘Bartzella’, not a generic yellow peony sold under a vague label. The flowers are fully double, bright yellow with a red central flare, and carry a mild sweet fragrance. For anyone serious about adding a proven Itoh to their garden, this is the most reliable path to success.
What works
- True ‘Bartzella’ cultivar with documented parentage
- Large 3-5 eye root establishes quickly
- Fragrant bright yellow double flowers with red flares
What doesn’t
- Root may arrive in two pieces from shipping breakage
- No bloom in first season as expected
2. Hazzard’s Bulbs Peony Itoh Bartzella
Hazzard’s version of the Bartzella Itoh peony offers an entry-level price point for gardeners who want to experience the large yellow blooms without committing to a premium nursery label. The bare root arrives neatly packaged, and multiple reviewers noted that it sprouted rapidly after planting in late summer. The one-root unit is smaller than the Burpee 3-5 eye grade, but the growth vigor reported in reviews — “grew immediately” and “deepest green plant” — suggests decent root viability for the price.
Like all Itoh hybrids, this peony will not bloom in its first season, and buyers should set expectations accordingly. One reviewer reported that when the plant finally flowered after two seasons, the blooms appeared pink rather than yellow, which raises a question about color fidelity on this particular lot. However, the majority of feedback describes the plant as healthy, hardy, and well worth the cost compared to expensive alternatives from specialty growers.
The real appeal here is gambling a smaller investment on a cultivar that, when it performs, produces the same large, fragrant yellow flowers that make Bartzella famous. If you have a spot in the garden where you are willing to wait two seasons for a payoff, this is a low-risk way to test whether Itoh peonies suit your soil and microclimate before spending more on a graded root.
What works
- Very affordable for the Bartzella cultivar
- Shipped well-packaged and alive
- Grows rapidly if planted immediately
What doesn’t
- Single bare root with smaller eye count
- Some reports of pink blooms instead of yellow
3. Marde Ross Sarah Bernhardt Double Pink Peony
Sarah Bernhardt is not strictly an Itoh hybrid — it is a classic herbaceous peony — but the double pink blooms are so universally desired by gardeners shopping for Itoh-like flower form that it earns its place here for comparison. The 3-5 eye bare root from Marde Ross arrives as a premium heirloom strain, and many buyers saw it bloom in the very first spring after fall planting, which is faster than most true Itoh hybrids will perform.
The root size is generous relative to the mid-range cost, and the plant grows to a manageable 3 feet tall, making it suitable for mixed borders without staking. The fragrance is strong and sweet, and the flowers are large enough to attract pollinators. The few negative reviews describe roots that arrived too small to produce blooms, or roots that rotted in the soil shortly after planting, which can happen with any bare root if the soil drainage is poor or if the root was stored improperly before shipping.
For gardeners in zones 3-8 who want that classic peony look — big, pink, fragrant, and reliable — without waiting three seasons for an Itoh to mature, this is the safer play. Pair it with a true Itoh like Bartzella to get both immediate gratification and long-term hybrid performance in the same garden bed.
What works
- Blooms sooner than true Itoh hybrids
- Strong root with 3-5 eyes in good condition
- Highly fragrant heirloom variety
What doesn’t
- Not an intersectional Itoh hybrid
- Some roots were too small to bloom first year
4. Pilestone Itoh Perennial Peony (Pink)
Pilestone’s offering is marketed as an Itoh perennial peony with a mature height of 5 feet, which is substantially taller than typical herbaceous peonies and closer to tree peony stature. The pink blooms are described as large and showy, and the plant is listed as GMO-free with partial shade tolerance. The premium price point suggests the grower is charging for the novelty of a tall, tree-like habit in a plant that dies back to the ground each winter.
Owner experiences are sharply divided. Several purchasers reported that the plant arrived well-packaged and survived for multiple seasons, growing into a beautiful specimen. However, a significant number of reviews describe rotten roots upon arrival, broken branches, dry leaves, and — most critically — a complete failure to bloom after years of growth. One verified buyer explicitly stated the plant “never bloomed,” which is the worst outcome for a peony purchase since the entire value proposition is the flower.
The variability in quality suggests inconsistent stock or handling. If you are willing to take a gamble on a tall pink Itoh-type peony that may arrive in good shape or may arrive compromised, the positive outcomes show the potential exists. For risk-averse buyers, the Burpee Bartzella is a much safer bet for a proven premium result.
What works
- Tall 5-foot mature height for dramatic presence
- Well-packaged when shipped properly
What doesn’t
- High failure-to-bloom rate reported
- Some roots arrived rotten or damaged
5. Willard & May Mixed Peony Jumbo Pack
This jumbo pack includes six bare-root peonies in white, pink, and red — a mix that allows you to fill a large border or create a cutting garden for a fraction of the cost of buying individually potted plants. The roots are graded at 2-3 eyes each, which is the minimum threshold for reliable growth, and the package is marketed as organic with fragrant flowers suited to full sun and well-drained soil in zones 3-8.
Customer feedback is polarized. On the positive side, several buyers received all six roots with sprouts already emerging, and those who planted immediately saw the peonies break through soil within 2-3 weeks. One reviewer even reported that all six blossomed in the first season, which is unusually fast for bare-root peonies. On the negative side, multiple buyers received only 5 roots instead of 6, or found the roots small and unlabeled, making it impossible to know which color was planted where.
The biggest risk with bulk packs is consistency: the labor cost of packing 6 individual roots means quality control sometimes slips, resulting in mix-ups, damaged buds, or missing pieces. If you are okay with the possibility of getting 5 good roots instead of 6, and you don’t mind not knowing which color is which until they bloom, the per-root cost is unbeatable for filling space quickly.
What works
- Very low cost per root for a mixed planting
- Some lots arrived already sprouting
What doesn’t
- Frequent short-shipping — 5 roots instead of 6
- Roots not labeled by color; mix unknown
6. Blooming & Beautiful Happy Birthday Camellia
The Happy Birthday Camellia produces large, deep pink blooms that are strikingly similar to a fully double peony in form, but it is an evergreen shrub that thrives in the warmer zones 7-10 where true peonies often struggle with heat. The 3-gallon pot size means you are getting a well-rooted plant with immediate presence — not a bare root that requires years to establish. Verified buyers universally praised the packaging speed and the health of the foliage upon arrival.
This Camellia japonica cultivar requires partial shade, well-drained acidic soil, and protection from hot afternoon sun, which is a different care profile than the full-sun, alkaline-soil-tolerant Itoh peony. The reward is a shrub that blooms in early to mid-spring with candy-striped pink petals and a long flowering window. The plants that were planted in the ground after shipping showed thriving new growth within months.
Shipping restrictions are significant: cannot be shipped to AK, AZ, CA, CO, HI, ID, MT, NM, NV, OR, UT, WA, or WY due to agricultural regulations. For gardeners in eligible states who want peony-shaped blooms without battling peony-specific diseases like botrytis blight, this Camellia is an elegant alternative that delivers immediate visual impact.
What works
- Large 3-gallon pot gives instant garden presence
- Peony-shaped blooms on an evergreen shrub
- Excellent packaging and shipping speed
What doesn’t
- Restricted shipping to many western states
- Requires acidic soil and partial shade
7. Stargazer Perennials Earth Angel Parfuma Rose
Earth Angel Parfuma is a modern rose bred specifically to produce large, peony-shaped blooms in cream and blush pink with a high petal count and a strong, sweet fragrance. It is grown on its own root, which increases hardiness and allows the plant to survive colder winters than grafted roses. The 1.5-gallon peat pot includes slow-release fertilizer and is designed to be planted directly without root disturbance, a major advantage over bare root plants.
The bloom performance is exceptional for a rose that mimics peony flower form: owners in zone 8b reported fragrant flowers by late May after a March planting, and the plant proved hardy enough to survive hailstorm damage and continue blooming. The mature size of 4-5 feet tall and 4 feet wide makes it suitable both for garden beds and large containers. The three-year update from one buyer confirms the rose reaches full size quickly and is often the first among dozens of roses to produce buds each season.
This is not a peony, but if your goal is peony-shaped flowers with a longer bloom season (April through September) and you have the full sun and regular watering this rose demands, the Earth Angel delivers a more consistent show over more months than any true Itoh peony can match. It is ideal for gardeners who want the peony aesthetic but need a plant that blooms reliably on first-year growth.
What works
- Blooms repeatedly April through September
- Own-root stock increases cold hardiness
- Intense sweet fragrance with high petal count
What doesn’t
- Requires regular watering and full sun
- Not a true peony — must be pruned as a rose
Hardware & Specs Guide
Eye Count and Root Size
The number of pinkish buds (eyes) on a bare root peony directly correlates with first-season growth vigor and the likelihood of second-season blooms. A 3-5 eye root is the industry standard for premium plants, while 2/3 eye roots are considered economy grade. Larger roots with more eyes also have greater stored energy reserves, making them more forgiving of imperfect planting depth or brief dry spells after installation.
Planting Depth for Itoh Hybrids
Unlike herbaceous peonies that require eyes 1-2 inches below the soil surface, Itoh peonies should be planted 2-3 inches deep to protect the graft union and encourage strong root development. Planting too shallow exposes the crown to frost heave in cold zones, while planting too deep prevents the eyes from breaking through at all. A layer of organic mulch after winter dormancy helps retain consistent soil moisture.
