When a lily flower has extra petals stacked into a full, ruffled center, it creates a visual impact that single-petal varieties simply cannot match. That layered bloom structure is the defining trait of double bloom lilies, and finding bulbs that reliably produce those dense, show-stopping flowers is the real challenge for any gardener.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time comparing bulb sizing charts, analyzing germination reports from verified buyers, and cross-referencing USDA hardiness data to separate strong perennial performers from one-season wonders.
Whether you’re planting a new border or refreshing an existing bed, choosing the right bulbs matters. This guide focuses on the best double bloom lilies available now, based on bulb quality, fragrance, and proven garden performance.
How To Choose The Best Double Bloom Lilies
Double bloom lilies are not a single species — the term refers to any lily variety where the reproductive organs have transformed into extra petals, creating a dense, layered flower head. Choosing strong bulbs that carry this genetic trait reliably requires attention to several specific factors.
Bulb Size and Circumference Grade
Lily bulbs are graded by their circumference in centimeters. A bulb measuring 14/16 cm is the standard minimum for a mature, flowering-size bulb. Larger sizes — 16/18 cm or 18/20 cm — store more energy and typically produce more bloom stems and larger flowers in the first season. Smaller bulbs may still grow but often take an extra year to reach full flowering potential.
Hardiness Zone Matching
Most double bloom lily varieties thrive in USDA zones 3 through 9, but the microclimate in your specific garden matters. Bulbs planted in zone 5 or colder benefit from a winter mulch layer to prevent freeze-thaw cycles from heaving them out of the ground. In zones 8 and 9, choose a planting spot with afternoon shade to keep the roots cool during intense summer heat.
Fragrance and Color Consistency
Double bloom lilies range from intensely fragrant Oriental hybrids to lightly scented Asiatic types. Review buyer photos carefully — multiple verified reports show that shipped bulbs sometimes produce different colors than the listing image. Stick with reputable sellers who guarantee true-to-variety blooms, especially if you are planning a specific color scheme.

In‑Depth Reviews
1. Stargazer Oriental Lilies (12 Pack of Bulbs)
This 12-pack of Stargazer Oriental lilies sits firmly in the premium category because every bulb ships at a mature 14/16 cm circumference, which is the industry standard for guaranteed first-season flowering. Verified buyers consistently report 100 percent germination rates even under challenging conditions like Texas summer heat, and the bulbs arrive plump with 1-inch sprouts already showing.
Each bulb produces multiple huge pink-and-white blooms with that classic, heavy Oriental fragrance that carries across the garden. The stems are sturdy enough to support the dense flower heads without staking, and the plants perennialize reliably, returning larger each year. The 100 percent grow guarantee from Willard & May adds extra confidence for first-time lily growers.
One buyer received 10 bulbs instead of the advertised 12, and deer definitely find these as appealing as you do — a wire cage or repellent spray is recommended if deer frequent your area. Color accuracy is excellent for the pink variety, though a few white-flowered bulbs have been reported in mixed batches. For pure double-bloom reliability in a classic Oriental, this pack delivers the most consistent results.
What works
- Mature 14/16 cm bulbs with strong sprout development
- Intense fragrance and large pink blooms mid-summer
- 100 percent grow guarantee from a reputable brand
What doesn’t
- Some packs arrive with 10 bulbs instead of 12
- Very attractive to deer — requires protection
- Color may vary slightly from photos in rare cases
2. Complete Flower Bulb Garden (75 Bulbs)
This collection bundles 78 bulbs across five varieties — Gladiolus, Harlequin Flowers, Stargazer Lilies, Asiatic Lilies, and Calla Lilies — to create a staggered bloom sequence from July through the fall frost. The mix includes 10 Stargazer and 5 Asiatic lily bulbs, giving you a solid foundation of double-style blooms alongside complementary shapes and textures.
Each bulb is packed individually with care, and the assortment is designed for gardeners who want a full-season display without having to research and order five separate packages. The hardiness range covers zones 3 through 9, and the bulbs perform equally well in full sun or partial shade, making this a versatile option for varied garden conditions.
Some buyers report that the Stargazer bulbs in this mix produce yellow flowers rather than the pink shown on the listing, so color expectations should be managed. A small percentage of bulbs may fail to sprout — about one in five buyers notes some duds in the batch. If you prioritize sheer quantity and variety over guaranteed color matching, this kit offers an impressive volume of planting material.
What works
- Five different bulb types for continuous July–October color
- Careful packaging with individual bulb protection
- Covers a wide hardiness range from zone 3 to 9
What doesn’t
- Stargazer bulbs may bloom yellow instead of pink
- Not all bulbs germinate — some batches have duds
- Requires planning for proper spacing of four varieties
3. 3 Pack Giant Pretty Lady Tree Lily Flower Bulbs
The Giant Pretty Lady Tree Lily is marketed for its towering height — over 8 feet tall with 8-inch blooms — and verified buyers confirm it reaches at least 5 feet after three seasons, making it one of the tallest options in this list. Each bulb produces upward of 30 pure white blooms per plant when fully established, and the flowers are fragrant enough to attract butterflies and hummingbirds.
The deer-resistant claim holds up reasonably well in practice — one buyer reported that two of three bulbs survived heavy deer damage and returned healthy the following year. The bulbs prefer partial shade and well-drained soil, and they are perennial in zones 3 through 9. The white blooms add a clean, dramatic vertical accent to the back of any border.
Not every bulb in the pack germinates — at least one review notes only 2 of 3 bulbs grew, and a few buyers received yellow blooms instead of the advertised pure white. The plants can become top-heavy in windy locations without a support stake. For gardeners willing to stake and wait for maturity, the visual payoff is genuinely impressive.
What works
- Extreme height with massive 8-inch white blooms
- Better deer resistance than typical Oriental lilies
- Perennial with increasing bloom count each year
What doesn’t
- Not all bulbs germinate — some packs have 2 of 3
- Color may shift to yellow instead of pure white
- Top-heavy in wind; requires staking for stability
4. Stella D’oro Yellow Daylilies (10 Bare Root)
Stella D’oro is the most recognized reblooming daylily variety in the trade, and this 10-root pack from Willard & May delivers healthy, No. 1 grade bare roots with visible sprouts already emerging. Buyers consistently report that all 10 roots arrive in excellent condition, with large, firm root systems that establish quickly in well-drained loam soil under full sun.
The yellow blooms appear repeatedly from early summer through fall, making this one of the longest-blooming options available. Each flower opens for one day, but the plant produces so many buds that the display remains continuous for months. The compact 12-24 inch height makes it ideal for front borders and edging along walkways.
The bare roots can arrive tangled, and novice gardeners may struggle to identify which end is up without printed instructions — a common complaint that would be easy for the seller to address. A small percentage of roots fail to establish, but the vast majority of verified reviews praise the health and vigor of the plants. For foolproof yellow color and repeated flowering, these are the standard.
What works
- All 10 bare roots arrive healthy with visible sprouts
- Continuous yellow rebloom from June through frost
- Compact 12-24 inch height suits front-of-border use
What doesn’t
- No planting instructions included for beginners
- Bare roots may tangle in the package
- A small percentage of roots fail to establish
5. Mixed Oriental Lily Bulbs (Pack of 8)
This entry-level 8-pack of mixed Oriental lily bulbs from Willard & May USA gives budget-conscious gardeners a fragrant start without sacrificing bulb size — all bulbs grade at 14/16 cm, the same mature circumference as premium packs. The assortment includes multiple color varieties, all producing that signature heavy Oriental perfume that fills a patio or entryway.
The plants reach 24 to 36 inches tall and bloom in summer, making them suitable for mid-border positioning in full sun. The sandy soil preference and moderate watering needs make these straightforward for beginners, and the zone 3-9 hardiness covers most of the continental United States. Each spring-planted bulb returns as a perennial if the soil drains well through winter.
Because the pack is mixed, you get no control over the specific colors that emerge — the result is a surprise each season. A few buyers note that the bulbs are smaller than expected upon arrival, though they still fall within the 14/16 cm grade. If your goal is simply to add fragrance and color on a tight budget, this pack delivers reliably for the cost.
What works
- Mature 14/16 cm bulbs at an accessible price point
- Strong Oriental fragrance from all color varieties
- Perennial in zones 3 through 9 with good drainage
What doesn’t
- Mixed colors offer no predictability in bloom appearance
- Some bulbs arrive slightly under the expected size
- Limited to 8 bulbs for larger planting areas
Hardware & Specs Guide
Bulb Circumference Grades
Lily bulbs are measured by their widest circumference. A 14/16 cm bulb is the standard for first-year flowering bulbs. Larger grades like 16/18 cm or 18/20 cm store more carbohydrate reserves, producing thicker stems and more bloom buds per plant. Always check the listed circumference — undersized bulbs often require a full growing season before they reach bloom stage.
USDA Hardiness Zones for Lilies
Most Oriental and Asiatic lily varieties thrive in zones 3 through 9. In zones 3 through 6, apply a 4-inch winter mulch after the ground freezes to prevent frost heave. In zones 7 through 9, choose a site with morning sun and afternoon shade to keep root zone temperatures moderate during peak summer heat.
