The Montana Rubens Clematis is the undisputed queen of fast-growing flowering vines, capable of smothering a fence, arbor, or wall in delicate pink blooms by late spring. But buying a live vine online is a gamble — the difference between a plant that thrives and one that arrives dead in the box comes down to knowing which nurseries ship a mature, healthy root system, not a fragile cutting.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent seasons comparing the actual shipped condition, bloom performance, and hardiness of dozens of clematis suppliers by studying verified buyer feedback and cross-referencing USDA zone claims against real grower reports.
After analyzing hundreds of user experiences, I’ve identified the five live clematis vines that reliably deliver on their promise. The list below is your shortcut to the best montana rubens clematis options available online — each one vetted for root quality, bloom color accuracy, and survivability in your specific growing zone.
How To Choose The Best Clematis Vine
Choosing a clematis vine online is fundamentally different from picking a hand tool. You are selecting a dormant or actively growing organism that must survive shipping stress and adapt to your microclimate. Three factors separate a thriving vine from a disappointment.
Container Size and Root Maturity
A plant shipped in a 2-inch pot is a seedling — it may take 2 to 3 years to reach bloom size. Vines sold in 4-inch or 8-inch containers have a developed root ball that establishes faster and flowers the first season. The “8’’ Size Container” listings from Green Promise Farms consistently arrive with roots fully filling the pot, minimizing transplant shock.
Pruning Group Compatibility
Montana clematis belongs to Pruning Group 1 — it blooms on old wood from the previous season. If you prune in spring, you cut off all the flower buds. Group 2 varieties like ‘Asao’ bloom on both old and new wood, giving you a second flush if you prune lightly after the first bloom. Group 3 types like Sweet Autumn bloom on new growth and can be cut to the ground in winter. Mixing pruning groups on the same trellis creates maintenance confusion.
Bloom Color and Fragrance Claims
Several verified reviews report receiving a white clematis when a pink variety was ordered. This is the most common complaint in this category. Look for sellers like Wekiva Foliage who include multiple photos showing the bloom at different maturity stages. Fragrance is another variable — ‘Asao’ is one of the few scented clematis, while most Montana hybrids have no noticeable smell.

In‑Depth Reviews
1. Asao Clematis – Wekiva Foliage
The Asao from Wekiva Foliage offers the best compromise between mature starter size and price — it ships in a 4-inch pot rather than the tiny 2-inch containers common at this price point. The deep pink petals with pale yellow centers produce the classic large single blooms, but the real differentiator is fragrance, which is unusual for a clematis. Several buyers confirm the flowers attract butterflies and that the vine reaches 8 to 10 feet in the first full season with proper support.
It belongs to Pruning Group 2, meaning it blooms on old wood in late spring and may produce a second flush on new growth in early fall. This gives you two windows of color per year rather than a single burst. The compact growth habit works well on a patio trellis or in a mixed container, and the deer resistance eliminates a common source of frustration for suburban gardeners.
The most frequent complaint involves color confusion — several reviews report a white bloom instead of pink. This is a known issue with Wekiva Foliage stock; if exact pink color matters more than vine health, consider paying more for a premium grower. A smaller group of buyers report the plant dying within weeks of arrival, though the majority of those cases involve improper watering or planting in full shade.
What works
- Fragrant flowers attract butterflies, rare for this category
- Larger 4-inch pot reduces time to first bloom
- Deer resistant, ideal for suburban fence lines
What doesn’t
- Color accuracy inconsistent — some arrive white instead of pink
- Higher mortality rate reported than premium 8-inch plants
2. Clematis Taiga – Wekiva Foliage
Taiga stands out for its semi-double and double blooms in a deep purple with yellow centers, a rare flower form in the clematis world. Some individual flowers approach 10 inches across — nearly dinner-plate size. This is a collector-grade plant for gardeners who want something beyond the standard single-petal look. Wekiva Foliage ships it as a 2-inch starter, so you are buying potential rather than immediate impact.
The vine grows vigorously once established, with the same basic care requirements as most large-flowered hybrids — full sun on the foliage, shaded cool roots, and a thick organic mulch layer. It fits best in USDA zones 4 through 8. Buyers report that the blooms attract hummingbirds and bees consistently, making it a strong choice for pollinator-focused gardens. The trailing growth habit also works as a ground cover if you lack vertical structure.
The small pot size is the main disadvantage. Several buyers received plants that appeared half-dead or extremely young, and recovery took a full growing season. One review notes that packaging was poor and the plant arrived damaged. The seller’s customer service responded quickly to cold-weather shipping issues, but the variable plant condition makes this a riskier purchase than a premium 8-inch container plant.
What works
- Exceptional double blooms up to 10 inches across
- Attracts hummingbirds and bees consistently
- Responsive seller support for damaged arrivals
What doesn’t
- Very small 2-inch pot delays bloom for 1-2 years
- Packaging complaints and variable plant condition
3. Sweet Autumn Clematis – Green Promise Farms
Green Promise Farms ships the Sweet Autumn Clematis in an 8-inch container, which is the largest pot size in this lineup. Multiple verified reviewers describe arriving plants as “lush,” “mature,” and “nearly doubled in size” within weeks. This is not a starter — it is a fully rooted vine ready to climb the first season. The white flowers appear in September and create a dense cloud effect that attracts bees heavily.
It belongs to Pruning Group 3, which is the easiest to manage: cut the entire vine back to 6 inches in late winter, and it regrows 10 to 15 feet by autumn. This makes it ideal for covering large pergolas or arches quickly. The hardiness extends to zone 4, and the plant tolerates sandy soil better than most clematis, which prefer loamy conditions. One buyer calls it “hard to find” in this size, confirming the scarcity of mature Sweet Autumn vines online.
The single bloom period is the main limitation. Unlike Group 2 varieties that flower in spring and again in fall, Sweet Autumn offers one late-season display. Some gardeners find the fragrant white flowers overwhelming in quantity — the vine can become a solid wall of white. If you want a spring pink Montana, this is not the right plant. But for sheer coverage speed and reliability, it outperforms every other option here.
What works
- Mature 8-inch container blooms first season reliably
- Fast growth to 15 feet, ideal for large structures
- Thrives in sandy soil where other clematis struggle
What doesn’t
- Single late-season bloom period only
- White flowers only — no color variation
4. Clematis Hyde Hall – Green Promise Farms
Hyde Hall from Raymond Evison is a compact clematis bred specifically for small-space gardens and partial shade positions. The mature height caps at 5 to 6 feet with a spread of 2 to 3 feet, making it one of the few clematis that fits comfortably in a container without overwhelming a balcony or patio. The white flowers are delicately scented, and the plant ships in an 8-inch container with a fully established root system.
Its partial shade tolerance is the standout feature. Most large-flowered clematis refuse to bloom with fewer than 6 hours of direct sun, but Hyde Hall performs well on north-facing walls or under a deciduous tree canopy. The USDA hardiness range extends to zone 9, which is wider than most Montana types. Buyers consistently report healthy arrivals with strong stem structure and minimal dieback after transplanting.
The 5- to 6-foot maximum height means Hyde Hall cannot cover a tall arch or fence the way a Montana or Sweet Autumn can. If your goal is rapid vertical coverage beyond 8 feet, this vine will disappoint. Also, the white flower color is less dramatic than pink or purple options. It works best as an accent plant near an entryway where its scent and tidy habit are appreciated up close.
What works
- Partial shade tolerant, rare for clematis
- Compact 5-6 ft habit fits containers perfectly
- Mature 8-inch container blooms first year
What doesn’t
- Limited height unsuitable for large structures
- White blooms lack the dramatic color impact
5. Clematis Edda – Green Promise Farms
Clematis Edda by Raymond Evison delivers the most dramatic flower color in this list — a deep purple petal with a distinct dark red bar down the center, resembling a velvet stripe. The 4-foot mature height is deliberately compact, designed for container growing on a patio or small balcony trellis. The blooming period spans from spring to fall, which is longer than most Group 2 varieties, giving you color for nearly three seasons.
Ships in the same 8-inch container format as other Green Promise Farms offerings, which means you get a plant that is ready to establish immediately. Multiple reviewers describe receiving a lush, green vine that doubled in size within weeks and outperformed competitors’ plants side by side. The regular watering requirement is slightly higher than average for clematis — Edda does not tolerate dry spells as well as the Sweet Autumn variety.
The 4-foot ceiling limits its use to small trellises or mixed containers. If you need a vine for a tall fence or pergola, this is not the right pick. The dark red bar color pattern is somewhat subtle from a distance and shows best when viewed up close.
What works
- Long bloom window from spring to fall
- Unique dark red bar on purple petals
- Mature 8-inch container for instant establishment
What doesn’t
- Only reaches 4 feet, not suitable for tall structures
- Requires more consistent watering than average clematis
Hardware & Specs Guide
Container Size vs. Root Maturity
Plants shipped in 2-inch pots are unrooted cuttings about 3 to 6 months old. They require a full growing season to develop a root system capable of supporting flowering. Four-inch pots contain a rooted plant that is 8 to 12 months old and may bloom in the first year if planted early. Eight-inch containers hold a plant that is 18 to 24 months old with a fully established root ball — these bloom reliably the first season and recover from transplant shock within days. When ordering a vine like the Montana Rubens, always check the pot diameter listed in the “Unit Count” or “Item Dimensions” section of the listing.
Pruning Groups Explained
Group 1 (blooms on old wood) includes Montana varieties. Prune immediately after flowering in late spring — never in winter or early spring. Group 2 (blooms on old and new wood) includes ‘Asao’ and large-flowered hybrids. Prune lightly after the first flush for a second bloom. Group 3 (blooms on new wood) includes Sweet Autumn and viticella types. Cut the entire vine to 6 inches in late winter. Misidentifying your clematis’s pruning group is the single fastest way to lose an entire season of flowers.

Final Thoughts: The Verdict
For most gardeners, the best montana rubens clematis winner is the Asao Clematis because it offers the best maturity-to-price ratio in a 4-inch pot with the rare addition of fragrant blooms. If you want a mature plant that blooms the first season in partial shade, grab the Hyde Hall Clematis. And for maximum vertical coverage with minimal maintenance, nothing beats the Sweet Autumn Clematis from Green Promise Farms.
