A low-growing plant with true blue flowers that knits into a living carpet is a rare find. You need a plant that fills bare soil, survives the seasons, and stays low-maintenance. This guide sorts nine proven blue-flowered ground covers by what they actually do in real garden beds, so you can match one to your light, your soil, and your patience level.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The best small blue flowers ground cover depends on your sunlight, your soil, and how quickly you need the bare spots filled in and blooming.
Our Picks at a Glance
How To Choose The Best Small Blue Flowers Ground Cover
Before you pick a plant, look at your yard’s reality. The best blue ground cover matches your sunlight, soil moisture, and hardiness zone — not just the prettiest flower photo. A full-sun plant will fail in shade, and a moisture-lover will struggle in dry, sandy soil.
Match the Plant to Your Hardiness Zone
Every perennial here lists a USDA hardiness zone range, which predicts winter survival. Planting outside that range risks the plant not returning next spring. Check your zone first, then the flower color.
Decide on Live Plants vs. Seeds vs. Bare-Root Vines
Live potted plants offer instant gratification and the highest survival rate — you see exactly what you plant. Bare-root vines are cheaper per square foot but demand careful handling and patience. Seeds are the budget route but require weeks of waiting and consistent watering, and results vary wildly from packet to packet.
Think About Foot Traffic and Spacing
Some ground covers, like Mazus and Blue Star Creeper, are tough enough to handle walking on between stepping stones. Others are purely ornamental. And spacing matters: plant 6 inches apart for a fast fill, or 12 inches apart to stretch your budget while waiting longer for coverage.

In‑Depth Reviews
1. Myrtle Vinca/Periwinkle Hardy Groundcover 50 Plants 2″ Pots
Our pick — over 4★ from 50+ verified ratings; the strongest balance of quality and price.
Fifty healthy starts that turn a shady, empty bed into a green carpet of blue blooms.
The sheer value here is the headline: you get 50 individual plants in 2-inch pots for the cost of a few quarts elsewhere. That’s a six-to-one count advantage over the single quart of Mazus reptans above, which means you can cover a real area in one season rather than waiting years for a lone specimen to spread.
This is the pick for tricky shade — it’s an evergreen ground cover vine for zones 4-9 that prefers part shade to shade, which is exactly where lawns and other ground covers give up. The plants are deer resistant, so they’ll survive the rabbits and deer that browse your other perennials. Spacing is flexible: at 6-inch spacing the flat covers about 12.5 square feet, while 12-inch spacing stretches the same 50 plants to roughly 50 square feet.
The health of these vines is what wins people over — buyers report healthy, well-prepared plants that were already thriving after transplant shock, with a common refrain that not a single one was lost. An occasional shipment can arrive struggling, but for a 50-plant order the strong consensus is that these establish reliably and start sprouting new growth within weeks.
What makes it the crowd favorite
- A full 50 plants means real coverage the first season
- Thrives in part shade to shade where lawns fail
- Deer resistant for low-maintenance planting
- Buyers consistently report healthy, thriving vines
Know before you buy
- Cannot ship to California due to soil regulations
- Young 2-inch plants need care to establish
Reach for this if: you have a large shady or partly shaded area that needs economical, fast coverage this year.
Look elsewhere if: you live in California or need a walkable path filler rather than a spreading vine.
2. UtopiaSeeds Baby Blue Eyes Seeds
The thrifty seed route that asks for patience and warm soil above 68 degrees.
Baby Blue Eyes (Nemophila menziesii) is a low-growing annual that carries dainty blue-and-white flowers from late winter through late spring or early summer, depending on your region. As a seed packet, it’s the most budget-friendly way into this category — you’re paying for many potential plants instead of one live pot.
The catch with any seed-based ground cover is the wait and the gamble. The planting guidance is clear — sow in spring, early summer, or fall when temperatures stay consistently above 68 degrees — and sandy soil suits it best. But the review experience splits sharply: some saw quick germination, while several found “nothing has grown” weeks later or plants that “never bloomed.” Seeds are living things that demand the right conditions, and they don’t come with guarantees.
If you’re a seasoned seed-starter who understands germination timing and has a spot with warm, well-drained sandy soil, this is a legitimately economical way to mass wildflowers across a rock garden or border. If you want a reliable, visible ground cover this season, a live plant will serve you far better than a packet of seeds.
The honest trade-off: Seeds are the cheapest entry point, but germination results are wildly inconsistent — some packets sprout quickly, others deliver nothing after weeks of waiting. It suits patient, experienced gardeners, not anyone needing guaranteed coverage.
3. Mazus reptans (Creeping Blue) Groundcover, 1 Quart
A one-inch-tall carpet that shrugs off footsteps between stones.
If you want a plant you can actually walk on, this is it. Mazus reptans stays a maximum of 1 inch tall, rooting as it spreads to form a tight mat of light green leaves, with bright blue flowers dotting the foliage in May and June. The manufacturer describes it as a “plant you can walk on,” making it the ideal filler between stepping stones on a path.
It’s a live, fully rooted quart plant — not a plug or seed — so you get immediate presence in the garden. Plant 18 inches apart and it will knit together over time, thriving in full sun to part sun. It’s hardy in USDA zones 5-8 and prefers moist soil, so keep it away from dry, sandy spots. Owners mention the plants arrived healthy, transplanted without shock, and were “thriving in my rock garden” within days of going in the ground.
Unlike the big 50-plant vinca flat, this is a single specimen, so plan to buy several for real coverage. The low-maintenance habit and toughness underfoot are its defining strengths, and the review pages back that up — healthy arrivals and quick recovery are the recurring themes.
Best for: pathways, rock gardens, and the spaces between pavers, plus carpeting under rose bushes.
Think twice if: you need to cover a large open bed quickly — one quart plant spreads slowly, so you’ll want multiple.
4. Plumbago Ceratostigma Deep Blue Flower Groundcover
Deep blue flowers that keep coming from spring until fall.
Most blue ground covers flower for a few weeks and call it a season. Ceratostigma plumbaginoides is different — it carries deep blue flowers from spring until fall, giving you months of color rather than a brief moment. That extended bloom time is the single biggest reason to choose it over the spring-only bloomers on this list.
This lot ships six starter plants, each in a 2-inch cell with soil, and mature plants reach 8-12 inches tall with a 12-18 inch spread. It’s an excellent ground cover for sunny to partly shaded areas across zones 5 to 10, growing at a medium-to-fast rate with moderate water needs and low maintenance. Note it ships as small starters and isn’t guaranteed to arrive in bloom.
Expect small plugs (young starter plants) when they arrive — one reviewer noted plants were “very small, not leafed out when it arrived.” The same review confirms it’s “now growing satisfactorily,” and others praised the tough, healthy plants that arrived securely packaged even in Oklahoma heat. Note: it doesn’t ship to Arizona.
Why it stands apart: The spring-to-fall bloom window is class-leading in this lineup — most rivals flower for just a few weeks. Just expect small starters that need a season to establish.
5. Vinca minor ‘Bowles’ (Periwinkle) Perennial
A single, fully rooted specimen of the classic blue-violet periwinkle.
This is the plant for someone who wants a mature, ready-to-establish specimen rather than a tray of plugs. It arrives in a #1 size container, fully rooted in soil, and can go straight into the ground upon arrival, weather permitting. It matures to just 4-6 inches tall but spreads 2-3 feet wide — a substantial footprint from a single plant.
It’s a named variety — Vinca minor ‘Bowles’ — known for its blue-violet flowers, and it’s suitable for USDA zones 4-8. The heirloom, organic material features and spring bloom period make it a garden classic. It handles moderate watering and performs best planted in spring.
The honest picture is mixed on establishment. The plant’s appearance wins praise, and many owners saw it thriving and blooming beautifully. But plant health gets genuinely mixed feedback — across the reviews, a common thread is that results take time, with several owners noting that year one brought little bloom and some plants never grew. That makes it a better choice for a patient gardener adding to an established bed than someone expecting instant coverage.
Choose it for: a quality single specimen with classic blue-violet color and a 2-3 foot mature spread.
skip it if: you expect fast, guaranteed establishment — this one wants patience and your best soil.
6. Isotoma fluviatilis (Blue Star Creeper) Groundcover
Sky-blue star flowers that form a dense, walkable 2-3 inch mat.
This is the closest thing to a living lawn you’ll find in blue. Blue Star Creeper produces adorable sky-blue star-shaped flowers from late spring through summer, with medium green rounded leaves forming a dense 2-3 inch mat. It’s explicitly marketed as ideal for small-area lawn replacement, tolerating heavy foot traffic and a variety of moisture levels and soil types.
The bloom performance is the standout feature — owners consistently report plants arriving with even blooms and gorgeous flowers, often “most were blooming” straight from the start. It’s hardy in USDA zones 5-9, handles full sun to part sun, and you plant it 10 inches apart to create that walkable carpet. Unlike the 50-plant vinca flat, this arrives as a single, fully rooted quart plant.
The plant quality and health are widely praised, with healthy quart-size containers and careful packaging the norm. Growing speed is the mixed note — some owners saw quick spreading, others found it slower to take off. One rare packaging miss saw a plant arrive loose in its box, but that’s the exception rather than the pattern.
Strong suits
- Handles heavy foot traffic like a lawn
- Arrives with abundant, even blooms per owners
- Adapts to varied moisture levels and soil types
Watch points
- Growth speed varies — some wait longer for spreading
- Single quart plant, so buy multiples for area coverage
7. Phlox Subulata Emerald Blue, Creeping Phlox
A dense evergreen mat of coveted blue-purple blooms that smothers weeds.
Creeping phlox earns its keep as a living weed barrier. The dense mat of evergreen foliage is thick enough that weeds can’t penetrate, making it a flower-covered, natural way to keep weeds at bay. Owners describe using it as “green mulch” in flower beds, where it slowly creeps and fills in while flowering in spring.
Those lavender-blue blooms are genuinely in demand — the listing notes Emerald Blue is “often hard-to-find due to the demand for its color.” It’s a 4-pack of ready-to-plant perennials grown in a Wisconsin greenhouse with over 40 years in operation, standing 6 inches tall and thriving in well-draining sandy soil. It’s deer resistant and, once established, drought tolerant with low feeding needs.
Most owners rave about the healthy, outstanding-condition arrivals and the easy re-acclimation instructions. The honest caveat: transplanting isn’t simple to use, and half the plants died for one owner after going in the ground. It’s a strong, vibrant plant that rewards careful transplanting into well-draining soil, especially in rock gardens where it roams over rocks and inhospitable areas.
The defining quality: This is the weed-suppressing workhorse of the group — a dense, evergreen, deer-resistant mat that also delivers coveted blue-purple flowers, as long as you transplant it carefully into sandy, well-drained soil.
8. 50 Creeping Myrtle Periwinkle Vinca Minor Vines
Fifty fast-growing evergreen vines for budget-friendly coverage of slopes and shade.
Like the top pick, this is a 50-vine bulk order — but a different format and price point. These are bare-root vines rather than 2-inch potted plants, which is the key distinction to understand. The listing emphasizes fast establishment into a “lush, evergreen carpet” with light blue flowers in early spring, thriving in full sun, complete shade, or semi-shaded areas.
Owners who had success describe easy handling: tangling roots separate simply after soaking, and plants survived even a week-long postal delay with green growth. One buyer planted a whole hillside, watered every evening through mid-summer heat, and saw reblooming by season’s end. The response is “that’s the way vinca works” — water at planting, then it thrives in shade where nothing else will grow.
The risk is the bare-root format. One large order saw 40% arrive dead with roots “tied in knots,” and another noted minimal root systems with low survival expectations. The strongest feedback centers on the plant itself — disease resistant, drought tolerant, low maintenance, and shade resistant — so your success depends on the condition your specific shipment arrives in.
Grab it if: you’re covering shade or a slope on a budget and are comfortable with bare-root planting after a soak.
Pass if: you want guaranteed potted plants — bare-root shipments are the gamble here.
9. Blue Daze | 10 Live Plants | Evolvulus Glomerata
Ten heat-loving, drought-tolerant plants for the sunniest, driest corners.
If your problem area is a baking, full-sun spot where everything crisps by July, Blue Daze is built for it. This perennial blooms continuously from spring through fall, producing vivid sky-blue flowers that attract pollinators, and it’s explicitly drought-tolerant and low-maintenance — minimal watering is all it asks for, making it ideal for busy gardeners.
The low-growing, spreading habit suits borders, ground covers, and rock gardens, with a compact bushy growth that creates a lush green backdrop for its blue blooms. It ships as a set of 10 live plants from Florida Foliage, and the plant’s 5-pound shipping weight tells you these are substantial specimens, not tiny plugs.
Feedback splits on arrival size and value. Happy owners describe “beautiful, healthy plants” with fast delivery and packaging that exceeded expectations, even after some hesitation from earlier reviews. On the flip side, a few found the plants disappointingly small — more like young starts than established plants — and noted similar sizes cost less at local nurseries. For a sun-blasted bed that needs a tough, blue-flowering spreader, this performs; just go in expecting young plants that need a season to size up.
The honest read: This is a low-maintenance, full-sun specialist with continuous spring-to-fall blue blooms — just manage your expectations on starter size, which a few owners flagged as smaller than hoped.
Understanding the Specs
USDA Hardiness Zones
This number tells you whether a perennial will survive your winter and come back next year. Each plant carries a zone range — like 4-9 or 5-8 — and planting outside that range is a gamble. If you’re in zone 7, anything that spans your zone has a fighting chance; if you’re in zone 3, stick to plants that start at zone 4 or lower.
Spacing and Coverage
How far apart you plant determines how fast the ground fills in. Closer spacing (6 inches) gives quick coverage but costs more plants; wider spacing (12-18 inches) stretches your budget but means waiting longer for the carpet to knit together. Check each plant’s recommended spacing before you order so you buy the right count.
Mature Height and Spread
The height tells you the texture of your ground cover — a 1-inch mat of Mazus reads as a living lawn, while an 8-12 inch Plumbago is more of a low shrub layer. The spread tells you how much ground a single plant will eventually claim, which matters for ordering the right quantity.
Sunlight and Foot Traffic
Some ground covers demand full sun, others genuinely prefer shade, and a few — like Mazus and Blue Star Creeper — are tough enough to walk on. Match the plant’s light needs to your actual bed, and think about whether humans or pets will be stepping on it regularly before you commit.
