The search for a clematis that delivers the deep, velvety red-magenta tones of ‘Ernest Markham’ without fading or flopping can feel endless. Mail-order vines often arrive as fragile plugs that spend a full season just catching up, leaving your trellis bare when you expected a cascade of flowers.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my days comparing root system maturity, grower pot sizes, and bloom-time reliability data from dozens of nurseries so you don’t have to gamble on a weak plant.
After digging through grower specs and verified owner reports on container size, hardiness zones, and first-year bloom performance, these five selections stand out as the most reliable ernest markham clematis options you can buy online today.
How To Choose The Best Ernest Markham Clematis
Buying a specific heritage cultivar like ‘Ernest Markham’ means you aren’t just shopping for a generic purple vine — you want the signature large, rich magenta-crimson blooms that define this classic. Choosing the wrong starter size or unproven seller can cost you a full growing season of disappointment.
Pot Size at Delivery: The Difference Between a Start and a Head Start
Most clematis sold online come in 2.5-inch or 4-inch starter pots. These are fine for patient gardeners, but they often require a year of root establishment before producing more than a handful of blooms. An 8-inch container or larger quart pot delivers a root mass that can support vigorous top growth and flowering in the same season you plant it.
Hardiness Zone Matching for Winter Survival
‘Ernest Markham’ is reliably hardy in USDA zones 4 through 9. If you live in zone 3 or colder, even the healthiest vine will need heavy winter mulching to survive. Always confirm the seller ships a plant grown in a zone range that matches your local climate — not just a generic “perennial” label.
Bloom Color Accuracy vs. Photos
Several reviewers report that the actual flower color can be lighter or have a central stripe compared to the stock photos. This is common with certain light conditions and soil pH. Reading recent buyer photos in the reviews section gives you a truer sense of what to expect than the nursery’s marketing images.

In‑Depth Reviews
1. Raymond Evison Clematis – Rebecca
The Raymond Evison ‘Rebecca’ arrives in a true 8-inch container with a fully rooted system that owners describe as “lush” and “quite grown up” — not a bare-root stick or a tiny plug. This is the single best way to get show-stopping red flowers in the same season you plant, especially if you want immediate vertical impact on a trellis or fence.
Multiple verified buyers report that this vine not only bloomed in its first year but returned even stronger in the second season, with buds forming early and flowers that attract hummingbirds. The brand’s reputation for breeding compact, free-flowering clematis means the genetic potential for rebloom is built in, not a gamble.
One buyer strongly objected to receiving a plant that matched a 4-inch plug inside an 8-inch pot, calling the presentation misleading. This seems to be an exception rather than the rule, but it’s worth noting the discrepancy in some shipments. For most gardeners, the vigor and flower quality justify the investment.
What works
- Large 8-inch container root mass for immediate first-year blooms
- Hummingbird-attracting red flowers with strong rebloom genetics
What doesn’t
- Inconsistent container size — some buyers report a 4-inch plug in an 8-inch pot
- Premium price tier compared to starter plugs
2. Perennial Farm Clematis Boulevard® Tranquilite™
The Perennial Farm Marketplace ‘Tranquilite’ ships in a massive 4-quart container — the largest root ball in this lineup — ensuring the plant arrives with substantial top growth and often multiple buds ready to open within days. Owners consistently describe the packaging as “excellent” and the vines as “the greenest, healthiest plants” they’ve ever had delivered.
This cultivar is a compact climber topping out at 4-5 feet, making it ideal for smaller trellises, balconies, or containers where a full-sized ‘Ernest Markham’ would be overwhelming. The pale lavender blooms offer a softer color profile, but the bloom period stretches from late spring through early fall with proper deadheading.
Because this is a hybrid series bred for compact growth and continuous flowering, it requires less aggressive pruning than species clematis. A light trim after the first flush is sufficient to encourage reblooming. The only trade-off is that the delicate lavender hue may not satisfy buyers seeking the intense magenta of true ‘Ernest Markham’.
What works
- 4-quart container provides the largest root mass for instant garden impact
- Compact 4-5 ft height perfect for patios and small trellises
What doesn’t
- Pale lavender color is far lighter than a classic magenta or red clematis
- Hybrid may not be as cold-hardy in extreme zone 4 winters
3. Easy to Grow Clematis Mrs. N Thompson
Easy to Grow’s ‘Mrs. N Thompson’ arrives in a 4-inch quart pot with an established root system that one buyer called “well-packaged and healthy.” While not as large as the 8-inch containers from premium growers, this plant is a significant step up from a 2.5-inch starter plug, offering faster establishment and a better chance of blooms in the first summer.
The deep purple and magenta blooms are classic clematis colors, and the brand explicitly notes this vine attracts pollinators and has an extended bloom time. Multiple 5-star reviews confirm the plant survived Sacramento summer heat and arrived in great condition, which speaks to the grower’s shipping and handling quality.
Buyers should note that this is a specific cultivar, not the exact ‘Ernest Markham’ — the bloom color may lean more purple-magenta than the true red-magenta of the heritage variety. Also, the 4-inch pot means you’ll still need to provide ample room and a strong support structure for the fast-growing vine to reach its full potential.
What works
- Established 4-inch pot with stronger root system than starter plugs
- Proven to handle heat in zone 8 climates like Sacramento
What doesn’t
- Not the exact ‘Ernest Markham’ cultivar — color may differ slightly
- 4-inch pot still requires a full season to reach mature size
4. YOKEBOM Burgundy Red Clematis Vine
The YOKEBOM Burgundy Red clematis is a true budget-friendly starter plant in a 2.5-inch pot. Buyers report arriving plants as “tiny but healthy” and often “doing very well” after a few weeks in the ground. One reviewer had two vines take off with “large flowers that are really impressive,” demonstrating that with care, this plug can produce stunning results.
The plant is labeled as “fragrant” and suited for sandy soil with moderate watering, making it a flexible option for less-than-perfect garden beds. The deep burgundy red color is intended to mimic classic red clematis tones, though one review noted the actual color was lighter than the listing photo with a small central stripe — a common issue with young vines that haven’t reached full genetic expression.
Two things to watch: this is a very small starter, so it will likely need a full growing season of root establishment before putting on significant top growth and heavy bloom. Additionally, one reviewer advised to “avoid any chips as possible” regarding packaging, suggesting some shipments may arrive with minor physical damage to the delicate stem.
What works
- Very affordable entry point for testing clematis in your garden
- Grows well in sandy soil with moderate water
What doesn’t
- 2.5-inch starter plug needs patience for first-season maturity
- Flower color may be lighter than the dramatic listing photos
5. YOKEBOM Purple Clematis Vine
This purple clematis from YOKEBOM is nearly identical to the burgundy red version in terms of packaging, pot size, and shipping practices. It comes as a 2.5-inch starter plant that buyers describe as “tiny but quite healthy” and “doing very well” after initial care. The vine is marketed as an heirloom variety, which suggests it retains its parent plant’s genetic purity and bloom characteristics.
The flowers are described as purple, and one buyer with multiple YOKEBOM clematis reported that this particular vine “took off” and produced impressive large flowers that brighten up a trellis. The plant prefers sandy soil and moderate watering, and it’s labeled as having a light fragrance — a nice bonus for a budget-friendly starter.
The same caveats apply as with the Burgundy Red: the 2.5-inch pot means a slow start, and the actual bloom color may diverge from the listing photo. One review noted dissatisfaction with “color not as expected,” where the flowers appeared lighter with a central stripe. For the price-conscious gardener willing to nurture a small vine, this is a solid entry-level choice.
What works
- Heirloom genetics preserve authentic clematis bloom characteristics
- Impressive large flowers reported by multiple satisfied buyers
What doesn’t
- Small 2.5-inch plug requires a full season of patience
- Bloom color may not match the promotional photos
Hardware & Specs Guide
Container Size at Delivery
The single most important spec for first-year performance is the pot size the plant ships in. A 2.5-inch starter plug holds about 0.2 quarts of soil, enough for a young root ball that needs a full season to establish. A 4-inch quart pot holds roughly 1 quart, giving you a several-month head start. The 8-inch containers and 4-quart pots from premium sellers provide a mature root system that supports immediate vigorous top growth and flowers in the same planting season.
USDA Hardiness Zone Range
All clematis in this list are rated for zones 4 through 9, meaning they can survive winter temperatures as low as -30°F in zone 4 and summer heat in zone 9. However, zone 4 gardeners should provide winter mulch around the crown after the ground freezes. Zone 9 growers need to ensure the vine gets afternoon shade to prevent flower fading and root stress.
