The Nora Barlow columbine is a double-flowered heirloom that replaces the classic spurred petals with a layered, pom-pom-like bloom in deep rose, burgundy, and cream. Gardeners who expect ordinary singles are surprised by the intricate, almost carnation-like form this aquilegia produces. That unique flower structure makes sourcing viable, true-to-type stock critical — a seed pack that promises blue singles won’t cut it.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent three years comparing nursery stock, analyzing owner germination reports, and studying the specific stratification requirements that make or break columbine success for home gardeners.
After sorting through five real options — from bulk seed packets to bare-root pint pots — this guide narrows the field to the most reliable candidates. Find the right fit among these hand-picked nora barlow columbine plants and skip the disappointment of dormant or mislabeled stock.
How To Choose The Best Nora Barlow Columbine Plants
Nora Barlow columbines are a specific Aquilegia vulgaris variety that produces fully double, spurless flowers. Because that trait is recessive and seeds can cross-pollinate, buying from a vendor that isolates the strain matters more than with open-pollinated singles.
Seed vs. Live Plant: Which start fits your timeline?
Seeds give you a larger patch for less money, but require a 3-4 week cold stratification period followed by warm germination — typically 80°F. A live plant in a pint pot skips that entire wait and can bloom the same season, but costs more and ships with root disturbance risk. Choose seeds if you have a refrigerator or cold garage to stratify; buy a nursery pot if you want guaranteed first-year flowers.
The stratification reality
Columbine seeds contain a natural germination inhibitor that only breaks down after cold, moist treatment. Scattering seeds on the ground in fall is the lazy version; controlled indoor stratification in damp paper towels inside a sealed bag at 35-40°F for three weeks gives you a 90%+ germination rate versus maybe 10-20% from natural fall sowing.
Bloom period and height expectations
Nora Barlow typically reaches 24-30 inches tall and blooms 4-6 weeks in late spring, with deadheading sometimes extending into early summer. A vendor claiming a 12-week bloom window for a single columbine is stretching reality unless they mean staggered flushes from multiple plants.

In‑Depth Reviews
1. Sweet Caroline Columbine Flowers – 5 Bulb Collection
This is a live bulb collection, not a seed packet — you receive 5 dormant root clumps in a mix of pink, purple, red, white, and yellow. The vendor claims a 12-week bloom window, which is optimistic for a single plant but plausible if you have multiple bulbs staggered by variety. Buyers report generous root systems that transition to soil faster than grocery-store bare roots, though a few received only 4 roots instead of the advertised 5.
The 36-inch mature height is taller than most columbines, making this a better mid-border choice than a front-edge accent. The organic material claim on the listing means no synthetic treatments were used on the stock, which matters for organic garden compatibility. Deadheading spent blooms can extend the show into early summer, but the natural bloom period is 4-6 weeks starting in late spring.
Roots arrived in June for one buyer, with minimal shoots but thriving new growth after planting — indicating the bulbs were dormant but viable. The mixed color palette gives you a rainbow effect without buying separate varieties, but if you specifically want the iconic double Nora Barlow form, these produce single flowers, not the spurless double type. For gardeners prioritizing immediate bloom volume over precise cultivar identity, this collection delivers fast visual payoff.
What works
- Live bulbs skip the seed-starting wait
- Mixed colors from a single purchase
- Organic material, good for clean gardens
What doesn’t
- Some buyers report receiving fewer than 5 roots
- Roots can be small and fail to establish
- Single flowers, not the double Nora Barlow form
2. Greenwood Nursery Wild Red Columbine – Live Pint Pot
This is a nursery-grown pint pot of Aquilegia canadensis, the native wild red columbine from Greenwood Nursery — a family-owned Tennessee grower with a 14-day guarantee. The plant ships in its pot, sleeved in craft paper to protect foliage and keep soil contained, then stabilized in a corrugated box with crunched paper and air pillows. Buyers consistently praise the packaging quality, with one calling it the best mail-order plant experience they’ve had.
At 12 inches mature height, this is a compact grower ideal for woodland gardens, rock walls, or front-of-border placement where taller hybrids would overwhelm. The red-and-yellow flowers are classic spurred singles, not the double form, but native pollinators — bumblebees and hummingbirds — prefer this species over hybrids. Greenwood’s guarantee requires contacting them within 14 days with evidence, so inspect immediately upon arrival.
One reviewer noted that the pot arrived with soil displaced for one of two plants, giving that plant only a 25% survival chance. That risk is inherent to live shipping, but the majority of feedback confirms healthy, vibrant arrivals. The bare-root option from the same store uses hydrating gel and moist paper wrapping, though the pint pot format is less prone to drying out than bare roots.
What works
- Nursery-quality packaging with a guarantee
- Compact 12-inch height fits small gardens
- Native species ideal for local pollinators
What doesn’t
- Not the double flower form
- Some plants arrive with disturbed soil
- 14-day inspection window is short
3. McKana Giant Hybrid Columbine Seeds – 600 Seeds
This is a 600-seed packet of McKana Giant Hybrid columbine from Marde Ross & Company, a licensed California nursery operating since 1985. The seeds are non-GMO and neonicotinoid-free. The real selling point is the color payoff: McKana hybrids produce large, multi-colored blooms (pink, purple, yellow, white, lavender) on stalks that can reach 32 inches — taller than most standard columbines. The mix is excellent for cutting gardens.
Germination success hinges entirely on stratification. One buyer reported a 96% germination rate after following a specific protocol: 4 weeks at 72-80°F in a pot covered with plastic, then 2-3 weeks in the fridge, then back to warm. Gardeners who scatter seeds in fall or skip the cold period frequently report zero sprouts. The seeds themselves are tiny and require surface sowing — do not bury them.
Several experienced gardeners reported no germination at all, suggesting that inconsistent handling during shipping — heat spikes or dry storage — can kill viability. The 600-count gives you enough volume to compensate for some loss, but if you need 100% certainty, buy two packets and start a controlled stratification batch first. Bloom time starts in late spring and can stretch into early summer with deadheading.
What works
- Large flower size on tall 32-inch stalks
- Non-GMO and neonicotinoid-free
- High volume for mass planting
What doesn’t
- Requires precise stratification to germinate
- Zero germination if cold period is skipped
- Some batches appear to have low viability
4. Blue Dream Columbine Seeds – 2800 Seeds
This is a 2800-seed packet of Western Blue Dream columbine from the same vendor as the McKana mix. The sheer volume is the draw — enough to cover a large border or meadow area without buying multiple packets. The blue color is the state flower of Colorado, producing classic spurred single blooms at 18 inches tall, zones 3-8. The seed is GMO-free, and the vendor claims fall-to-spring planting windows.
Buyer experiences are split: several report smooth arrivals and trust the vendor after multiple orders, but one repeated customer tried twice with zero germination, even using potting soil instead of direct ground sowing. That pattern suggests the same stratification dependency as other columbine seeds. The packets arrive with sowing instructions, but those instructions may not emphasize the cold pretreatment that experienced growers use.
One buyer used the seeds for wedding gift bags, noting the tiny seed size required ordering plenty for visual presence. That confirms the 2800 count is realistic for bulk projects, but each seed is dust-like and easily lost if not handled carefully. For gardeners who want a true-to-type blue patch without waiting for a nursery plant, this packet offers the best cost-per-seed ratio available.
What works
- Massive 2800-seed count for large areas
- Classic blue columbine color
- Vendor is established since 1985
What doesn’t
- Zero germination without proper stratification
- Tiny seeds are easy to lose
- Not the double flower form
5. Southern Living Obsession Nandina Shrub – 2 Gallon
This is not a columbine — it’s a 2-gallon nandina shrub from the Southern Living plant collection. It appears in the search results because columbine and nandina are sometimes grouped under “perennial wildflower” or “woodland plant” categories. It produces no blossoms and instead features bright red foliage that transitions from green to red/green by fall. The 48-inch mature height makes it a far bigger plant than any columbine.
USDA zones 6-10 suit this nandina; it is not cold-hardy below zone 6. It requires watering twice weekly until established, then once weekly. Buyers consistently praise the packaging quality and the vibrant, healthy condition of the shipped plants, though one noted that delivery handlers can tear the box and spill soil. The shrub is low-maintenance after establishment and provides year-round color where columbines go dormant in winter.
If you are specifically looking for Nora Barlow columbine, this product does not match. But if a delivery mishap or search algorithm dropped it into your list and you’re open to a non-flowering, foliage-forward alternative that blooms with color instead of petals, this nandina offers a different kind of visual punch. Just know it’s a completely different plant category — more akin to a compact hedge than a garden border flower.
What works
- Vibrant red foliage in all seasons
- Excellent packaging and plant health
- Low maintenance after establishment
What doesn’t
- Not a columbine — no blooms ever
- Only hardy to zone 6
- Taller than most columbine gardeners expect
Hardware & Specs Guide
Cold Stratification — The Make or Break Step
Columbine seeds contain natural germination inhibitors that only break down with 3-4 weeks of moist cold (35-45°F). Refrigerator stratification in damp paper towels inside a sealed bag is the most reliable method. Fall sowing outdoors works only if soil temperatures stay cold long enough — a warm winter means zero germination.
Plant Type vs. Bloom Form
Not all columbines are alike. Single-flowered varieties (like Blue Dream or McKana Giants) produce the classic spurred shape. Double-flowered varieties (like true Nora Barlow) are a different Aquilegia vulgaris subspecies that lacks spurs and forms showy pom-poms. Seed packets from outdoor-nursery bulk vendors are almost never the Norton Barlow type unless explicitly labeled.
