Finding true Phlox Sherwood Purple stock, with its iconic low-growing mat and vivid lavender-purple blooms, often means navigating a market flooded with look-alike seed mixes and unlabeled bare roots. The wrong choice leads to a season of unwanted heights or colors that clash with your design.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years analyzing nursery catalogs, comparing hardiness data across suppliers, and cross-referencing verified buyer feedback to identify which phlox offerings actually match their descriptions.
This guide cuts through the confusion to help you select the best phlox sherwood purple options available, ensuring your garden gets the vigorous, true-to-type ground cover it deserves.
How To Choose The Best Phlox Sherwood Purple
Sherwood Purple is a specific cultivar of moss phlox (Phlox subulata), prized for its dense, evergreen mat and prolific violet-blue flowers. Unlike annual phlox or tall garden phlox, this is a low-growing perennial that spreads slowly. The biggest mistake buyers make is assuming any purple phlox seed is the same — it simply isn’t.
Start with Live Plants, Not Seeds
Phlox Sherwood Purple does not come true from seed. If you want the exact color, habit, and hardiness of this named cultivar, you must purchase rooted starts or container-grown plants. Seed packets labeled “purple phlox” will almost always yield a different plant, often taller and less compact.
Check the Rootstock Quality
A premium nursery start arrives with a fully developed root system in a #1 container or a well-packed root mass. Dry, brittle roots or pot-bound specimens are signs of poor handling. Look for material that feels heavy for its size — light pots often mean dried-out soil and stressed roots.
Verify Hardiness and Regional Fit
Phlox Sherwood Purple performs best in USDA zones 4-9. If you live in a hot, humid region (zone 9 or above), or in an arid zone, pay close attention to moisture needs and sun exposure. A plant that thrives in Wisconsin may struggle in Oklahoma without extra care during shipping and establishment.

In‑Depth Reviews
1. Volcano Phlox Purple w/ White Eye (Green Promise Farms)
This premium nursery start from Green Promise Farms delivers a fully rooted plant in a #1 container — no germination guesswork, no bare-root gamble. The Volcano series is bred for sturdy, compact growth, reaching 18-24 inches tall with a strong 12-15 inch spread. The purple flowers with white eye are a classic combination that matches the visual intent of a Sherwood Purple style ground cover or border accent.
Buyer reports confirm the plant arrives large and well-packed, with several reviewers noting it survived shipping stress and returned even larger the following spring. The sweet fragrance is an added bonus for patio or deck placement. However, summer shipping to hot climates like Oklahoma has resulted in dried-out or DOA specimens — timing your order for spring or fall is critical.
One verified buyer described a pot-bound, broken plant on arrival, though this appears isolated. The overwhelming majority (4-5 star) cite excellent health, fast shipping, and vigorous regrowth. For a true, named phlox variety with predictable color and habit, this is the strongest option in the lineup.
What works
- True-to-name purple/white blooms, not a mix
- Fully rooted #1 container for immediate planting
- Proven hardiness in zones 4-8 with strong regrowth
What doesn’t
- Summer shipping risk in hot regions
- Potential for pot-bound roots if stored too long
2. Phlox Subulata Emerald Blue (Winter Greenhouse) 4pk
This 4-pack of Phlox subulata ‘Emerald Blue’ from Winter Greenhouse is the closest match to the true Sherwood Purple ground-cover habit. It forms a dense, evergreen mat just 6 inches tall, smothering weeds and covering rocks with a carpet of blue-lavender flowers in spring. Unlike tall garden phlox, this stays low and spreads — exactly what a moss phlox buyer expects.
Grown in a Wisconsin greenhouse with over 40 years of nursery experience, these are U.S.-grown live plants, not imported seed. Reviewers consistently praise the health of the plants upon arrival, with one buyer calling them “phloxnomenal” and reporting vigorous creeping and spring flowering. The natural weed-suppression and drought-tolerance once established are major selling points for ground cover use.
The main caveat: about half the plants died during transplanting for one reviewer, suggesting sensitivity to abrupt environmental change. The shipping box is packed with care, but the plants need gradual acclimation (as the included instructions recommend). For a reliable, low-growing purple-blue ground cover, this pack delivers premium performance.
What works
- Low matting habit (6 inches) ideal for ground cover
- Evergreen foliage with profuse spring bloom
- U.S. grown nursery stock, well-packaged
What doesn’t
- Transplant shock possible in some conditions
- Not a named Sherwood Purple cultivar — close color match
3. Perennial Farm Marketplace Phlox paniculata ‘Jeana’
‘Jeana’ is a standout tall garden phlox (Phlox paniculata), not a ground cover, but its exceptional mildew resistance and floriferous lavender-pink blooms make it a must-mention for anyone wanting a reliable, fragrant phlox. It reaches 3-4 feet tall, producing smaller-than-usual flower clusters in remarkable quantity. Cutting back halfway in June encourages even more stems.
Buyers rave about the packaging — a sturdy box with minimal plant stress. One reviewer noted a slightly wilted top that revived fully after watering. Multiple 5-star ratings call the plants “healthy as can be” and better than expected. This is a strong mid-range option for the back of a border or a pollinator garden where Sherwood Purple’s low habit isn’t the goal.
Note: ‘Jeana’ does not ship to AK, AZ, CA, CO, ID, MT, NV, OR, UT, WA, or HI due to agricultural regulations. Its height and upright growth are entirely different from a creeping phlox — make sure your garden design needs a 48-inch vertical accent, not a 6-inch carpet.
What works
- Superior powdery mildew resistance among tall phlox
- Fragrant, pollinator-attracting blooms
- Excellent packaging and healthy live plants
What doesn’t
- Upright habit, not a ground cover
- Restricted shipping to several western states
4. Willard & May Tall Phlox Mix — 6 Roots
This budget-friendly bare root bundle from Willard & May offers six roots in a mix of Blue Boy (blue), David (white), Peppermint Twist (white/pink), and Star Fire (pink). It’s an economical way to fill a border with tall phlox, but there’s no named Sherwood Purple here — the colors are a gamble, and the plants are upright, not creeping. The value is in quantity, not predictability.
Buyer experiences split sharply: some reviewers report nearly all roots sprouted into healthy, tall plants by the second year (one noting they exceeded 5 feet tall). Others report zero growth after following the instructions exactly, with no way to contact the seller. The root-soaking step (warm water before planting) appears critical — several failures skipped it.
For a budget-conscious gardener who wants a mass of tall phlox in multiple colors and is willing to accept some loss, this is a reasonable gamble. But if you need a specific low-growing purple ground cover, these roots will not deliver Sherwood Purple. The inconsistency in viability makes it a risk, not a reliable choice.
What works
- Six roots for a low price, good for filling space
- Second-year plants can become very tall and vigorous
- Mix provides color variety
What doesn’t
- High failure rate — some roots never sprout
- Bare roots require precise pre-soaking and timing
5. Outsidepride Scarlet Phlox Seeds — 1/8 lb
This bulk seed pack from Outsidepride is an annual Phlox drummondii in scarlet red — not perennial, not purple, not creeping. It grows 8-20 inches tall and self-seeds, meaning it may return year after year if conditions are right, but it’s a completely different plant from Sherwood Purple. The rose-red blooms are striking in containers and borders, but they won’t form a low mat.
Germination results are mixed: some buyers in Florida report excellent sprouting and floriferous blooms in sun and shade, while others saw only weeds after a month, with only 20 of 100 seeds emerging. The label advises sowing at 70°F with 1/16 inch depth and 12-inch spacing, but real-world conditions vary widely. The seed is GMO-free and adaptable to zones 3-10.
This is a budget option for someone who wants to experiment with phlox seeds, not a substitute for a named perennial cultivar. If you specifically need Sherwood Purple’s habit and color, skip this. But if you’re open to a cheerful self-seeding annual with deer-proof qualities, it’s a low-risk entry point.
What works
- Extremely low cost for a large quantity of seed
- Self-seeding annual can naturalize in the right spot
- Deer resistant and pollinator friendly
What doesn’t
- Not Phlox subulata — annual, upright, scarlet red
- Inconsistent germination rates reported
Hardware & Specs Guide
Plant Type & Habit
Phlox Sherwood Purple is a creeping moss phlox (Phlox subulata) — a low-growing, evergreen perennial that forms a dense mat 4-6 inches tall. It spreads by rooting along the stems, making it ideal for rock gardens, slopes, and border edges. By contrast, tall garden phlox (Phlox paniculata) stands 3-5 feet tall and does not creep. Always confirm the subulata species designation if you want a ground cover.
Hardiness & Sun Requirements
Phlox subulata is hardy in USDA zones 3-9, though Sherwood Purple performs best in zones 4-8. It requires full sun (at least 6 hours daily) for optimal flowering and mat density. In partial shade, it will still grow but may bloom less profusely. Well-drained soil with moderate moisture is ideal; waterlogged clay can cause root rot.
