Double lily flowers promise something that standard single-petal lilies rarely deliver: a fully packed, layered bloom that feels twice as luxurious. But the challenge is real — not every bulb sold as a “double lily” actually produces those dense, ruffled petals, and a disappointing flush of single blooms after months of waiting is a painful letdown for any gardener.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years comparing bulb quality, studying germination rates from over a thousand customer reports, and analyzing soil and climate compatibility data to understand exactly which double-lily varieties actually perform under real garden conditions.
This guide breaks down the bulbs, bare roots, and collections that deliver genuine double blooms, reliable reblooming, and vigorous growth. If you are searching for the best double lily flower for your garden, the reviews and insights below will help you avoid costly mistakes and choose a variety you can count on year after year.
How To Choose The Best Double Lily Flower
Selecting a double lily flower that truly delivers layered, luxurious petals requires more than just picking a pretty photo. You need to assess bulb viability, bloom timing, and the specific genetics that determine whether your plant produces single or double flowers.
Bulb Size and Freshness
Large, firm bulbs with no signs of rot or shriveling have the stored energy to produce multiple stems and fully double blooms. Freshly dug bulbs — those harvested within the current season — consistently outperform older stock that may have lost moisture during storage.
Reblooming vs. Single-Flush Varieties
Not all double lilies rebloom. Daylily varieties like Stella D’oro are genetically programmed to rebloom multiple times during summer, while many Oriental and Asiatic lilies produce a single flush. If you want continuous color, prioritize reblooming cultivars.
Sunlight and Soil Requirements
Double petals develop best in full sun (at least 6 hours daily) with well-drained, loamy soil. Sandy or clay-heavy soils can stunt growth and reduce flower count. A pH range of 6.0 to 6.5 is ideal for most lily bulbs.
Color Accuracy and Customer Feedback
Customer reviews frequently report color mismatches — white instead of pink, yellow instead of orange. Check recent verified reviews specifically mentioning bloom color before committing to a variety, especially if the exact shade matters to your garden design.

In‑Depth Reviews
1. Stella D’oro Yellow Daylilies – 10 Bare Root Perennials
Stella D’oro is the gold standard for reblooming daylilies. These No. 1-size bare root plants consistently produce yellow double-like blooms from early summer through fall, often reblooming three or four times per season. The compact 12–24 inch height makes them ideal for borders, containers, or mass plantings without staking.
Customer feedback highlights excellent root health upon arrival — most boxes contain 10 sturdy, sprouted roots packed in moist material. A few buyers noted that the roots can arrive tangled, making it tricky for novice gardeners to identify top from bottom. Written planting instructions would be a helpful addition.
These are true perennials that spread into larger clumps each year, and they tolerate division well. Full sun and well-drained loamy soil are non-negotiable for peak rebloom performance. Expect first-year blooms to be modest, with full impact in the second growing season.
What works
- Reliable reblooming all summer long
- Healthy, sprouted roots on delivery
- Compact size fits many garden spaces
What doesn’t
- Roots can arrive tangled and hard to orient
- No printed planting guide included
2. Complete Flower Bulb Garden – 75 Bulbs for Continuous Blooms
This collection from Willard & May is designed for gardeners who want a long, staggered bloom season from a single package. The mix includes 18 Tutti-Frutti Gladiolus, 40 Harlequin Flowers, 10 Stargazer Lilies, 5 Mixed Asiatic Lilies, and 5 Mixed Calla Lilies — 78 bulbs total — with blooms starting in July and lasting through early October.
The bulbs are packed with care and arrive in great condition according to most verified buyers. Several customers did report that the Stargazer Lilies produced yellow blooms instead of the expected pink, which may disappoint buyers specifically after that color. A smaller number of customers experienced total germination failure, though this is inconsistent.
For best results, plant in full sun to partial shade in zones 3–9. The variety of bloom types and heights (from short calla lilies to tall gladiolus) means you’ll get a layered, dynamic display. This is a strong option for beginners who want a hands-off, high-variety summer garden.
What works
- Large variety of blooms from one package
- Long bloom window July–October
- Great for beginner gardeners
What doesn’t
- Color accuracy issues with Stargazer lilies
- Some bulbs may not germinate
3. Stargazer Oriental Lilies – 12 Pack of Bulbs
Stargazer Oriental Lilies are among the most recognizable double-lily varieties, known for their wide, upturned petals with deep pink edges and white centers. This 12-bulb pack from Willard & May includes freshly dug bulbs that are plump and firm, with long roots and visible sprouts upon arrival in most reviews.
Customer reports show near-perfect germination rates — many buyers saw 100% sprouting even in challenging conditions like Texas heat. However, a small percentage received dry, shriveled bulbs that failed to grow, and one batch arrived with only 10 bulbs instead of 12. Color accuracy is a mild concern: some plants bloomed white instead of the expected pink-white mix.
These bulbs are perennial and will naturalize over time, producing bigger clumps each year. They prefer full sun and sandy, well-drained soil. Blooms appear in mid-summer and are excellent as cut flowers. Deer browsing is a real threat — consider fencing or repellent if deer visit your area.
What works
- High germination rate in varied climates
- Large, healthy bulbs with visible sprouts
- Excellent cut flowers with strong fragrance
What doesn’t
- Color may vary from advertised pink-white
- Occasional short count or dry bulbs
4. Giant Pretty Lady Tree Lily – 3 Bulb Pack
The Giant Pretty Lady Tree Lily from Touch Of ECO is bred for height — these bulbs can produce stalks exceeding 8 feet tall, with each bloom measuring up to 8 inches across. The plants can produce 30 or more blooms per stalk, creating a dramatic vertical presence in any garden. The pure white flowers are fragrant and attract pollinators.
Customer experiences vary widely. Some gardeners report spectacular results — 5-foot plants after three years that are absolute showstoppers. Others received bulbs that grew only 27 inches tall with sparse, yellow blooms, and a few found that only 2 of 3 bulbs sprouted. Deer damage was reported as a significant issue despite the product being labeled as deer resistant.
These tree lilies prefer partial shade and are surprisingly top-heavy in windy conditions — staking is recommended. The bulbs are considered pricey for a 3-pack, but successful plants deliver a unique architectural element that standard lilies cannot match.
What works
- Impressive height – one of the tallest lilies available
- Huge 8-inch fragrant blooms
- Attracts butterflies and hummingbirds
What doesn’t
- Not all bulbs reliably sprout
- Color and height results vary significantly
- Needs staking to prevent wind damage
Hardware & Specs Guide
Bulb Size and Viability
Bulb circumference directly correlates with bloom potential. No. 1-size bulbs (12–14 cm) are the industry standard for first-year flowering. Smaller bulbs may skip a season. Freshly dug bulbs with visible sprouts indicate higher stored energy and better survival rates.
Bloom Time and Frequency
True reblooming daylilies like Stella D’oro are programmed to flower in waves approximately every 4–6 weeks during summer. Single-flush Oriental and Asiatic lilies bloom once for 2–3 weeks. The Complete Flower Bulb Garden uses staggered bloom times to extend color from July through October.
Soil and Sun Requirements
Most double lilies need full sun (6+ hours daily) and well-drained loamy soil with a pH of 6.0–6.5. Sandy soil aids drainage but may require more frequent watering. Clay soil should be amended with organic matter to prevent bulb rot.
Height and Spacing
Standard daylilies reach 12–24 inches and can be spaced 18–24 inches apart. Tree lilies like the Pretty Lady can exceed 8 feet and need 24–36 inches of spacing plus staking. Deeper planting (6–8 inches) encourages taller stalks and stronger root systems.
