The search for a resilient, flowering ground cover that can handle foot traffic without losing its charm ends with a low-growing perennial that forms a dense, soft mat. Many options struggle under pressure or require constant maintenance, but the right choice delivers a lush, green carpet dotted with delicate blue flowers from spring through fall.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I specialize in dissecting horticultural data, analyzing owner feedback, and comparing the real-world performance of ground-cover varieties to match gardeners with the right plants for their specific conditions.
After weeks of research, I’ve narrowed the field to the five strongest contenders. This guide breaks down what makes a great option for your landscape and presents the top performers to help you choose the best blue star creeper plant for your garden or walkway project.
How To Choose The Best Blue Star Creeper Plant
Not every ground cover is created equal, especially when you need a plant that tolerates light foot traffic between pavers or creates a living carpet under taller plants. Understanding a few key factors will steer you toward the right choice.
Foot Traffic Tolerance and Mat Density
The primary use for a plant like Blue Star Creeper is covering areas that get stepped on. Look for a plant that forms a tight, low mat of foliage—typically under 3 inches tall. This structure allows the leaves to withstand pressure from footsteps without breaking or creating bare patches. The denser the mat, the better it recovers.
Sunlight and Moisture Adaptability
A versatile ground cover should thrive in both full sun and partial shade. Check the expected light requirement range. For moisture, a preference for consistently moist, well-drained soil is standard, but some varieties handle dry spells better than others after establishment. Matching these needs to your specific garden spot is critical for long-term health.
Spread Rate and Mature Coverage
Some plants spread slowly, while others can fill in a 1-foot gap in a single season. For a ground cover, a fast growth rate is generally a benefit—it means fewer plants needed and quicker coverage. Pay attention to the spread width at maturity. A plant that spreads 18 inches wide will require fewer specimens per square foot than a slower-spreading alternative.

In‑Depth Reviews
1. Greenwood Nursery Blue Star Creeper (Isotoma Fluviatilis)
This is the authentic article—live Blue Star Creeper plants shipped in pint pots. The dense mat habit reaches just 3 inches tall while spreading up to 18 inches, which is the ideal profile for filling spaces between stepping stones and rock garden crevices. Its tiny, star-shaped light blue flowers appear intermittently from spring to fall, adding color without overwhelming the foliage.
The plant is semi-evergreen, providing year-round interest in warmer zones (5 through 10) and a softer green presence in cooler climates. Greenwood Nursery packs each order with care, shipping the plants in fitted boxes with protective craft paper. They back their shipment with a 14-day guarantee, which covers transit stress if you contact them promptly.
One of the most practical features is its versatility: it thrives in full sun or partial shade and tolerates moderate foot traffic once established. If you need a reliable living carpet that establishes quickly, this is the most direct path to a mature ground cover without waiting for seeds to germinate.
What works
- Immediate, established plants rather than seeds
- Perfect 3-inch height for walkway crevices
- Tolerates both full sun and partial shade
- Blooms repeatedly from spring through fall
What doesn’t
- Premium investment for two pint pots
- 14-day guarantee window is relatively short
- Not fully evergreen in colder zones
2. HOME GROWN Wildflower Seeds Bulk Mix
This 3-ounce mix packs an impressive 47,400+ non-GMO, heirloom seeds spanning 19 wildflower varieties, including Black Eyed Susan, Purple Coneflower, and Blue Flax. It is designed for gardeners who want to create a vibrant, pollinator-friendly meadow or cottage-style bed. The included varieties are chosen for staggered bloom periods from spring through fall, ensuring continuous color and food for bees and butterflies.
Each seed type has been tested for high germination rates, and the mix is U.S.-sourced. The package includes detailed growing instructions, making it accessible for beginners. Many of the species also contribute to soil health, acting as green manure or nitrogen fixers, which benefits the overall garden ecosystem.
While this is not a single-species ground cover like the Blue Star Creeper, it is an excellent option for larger-scale projects where biodiversity is the goal. The mix reaches a mature height of about 18 inches, so it is better suited for open meadows than for tight spaces between pavers.
What works
- Exceptional seed count for the investment
- Curated for continuous bloom from spring to fall
- Includes soil-improving nitrogen fixers
- Clear instructions for successful germination
What doesn’t
- Not suitable for tight, high-traffic areas
- Requires full sun for best performance
- Annuals need reseeding for future seasons
3. Marde Ross & Company Creeping Thyme Seeds
For gardeners on a budget who are willing to invest time and patience, this seed pack offers over 8,000 seeds of Creeping Thyme—a dwarf ground cover that is well-known for its ability to handle moderate foot traffic. It grows to just 6 inches tall and produces purple blooms in the summer, making it a viable alternative for walkway borders and pathways.
Creeping Thyme is drought-tolerant once established and requires full sun to Partial Sun. The seeds are GMO-free and sourced from Marde Ross & Company, a California-based nursery since 1985. The expected planting period spans spring to fall, and the soil should be kept moist until germination occurs.
One key difference from Blue Star Creeper is that Creeping Thyme has a distinct fragrance and a slightly taller profile. While it is a resilient ground cover, it does not form as dense or low of a mat as the live Blue Star Creeper plant, and it requires more upfront effort to grow from seed.
What works
- Extremely low cost per square foot of coverage
- Drought-tolerant after establishment
- Fragrant foliage adds sensory interest
- Moderate foot traffic tolerance
What doesn’t
- Requires patience for germination and maturing
- Reaches 6 inches, not as low as Blue Star Creeper
- Does not tolerate partial shade as effectively
4. Marde Ross & Company Forget Me Not Seeds
These Forget Me Not seeds produce clusters of sky-blue flowers with bright yellow centers, adding a soft, delicate color to shaded areas. The plants grow 6-12 inches tall and bloom from spring to summer, making them an excellent option for weaving through borders or underplanting tulips and other spring bulbs. They are known for attracting early-season pollinators.
The seeds are kept in temperature-controlled storage to preserve freshness and are guaranteed to germinate. They are GMO-free and untreated. Marde Ross & Company recommends scattering the seeds in fall or early spring in moist, well-drained soil where the plant can receive partial shade or sun. Germination occurs in 10-20 days, and the plant is hardy in zones 3-9.
Unlike Blue Star Creeper, Forget Me Nots do not form a dense, foot-traffic-tolerant mat. They are better suited for bringing color to shadier spots and naturalizing among taller plants. If your goal is a low carpet for a walkway, these are not the right choice, but they excel at filling nectar gaps for early pollinators.
What works
- Thrives in partial shade where many ground covers fail
- Reliable germination with treated seeds
- Provides early spring nectar for bees
- Ideal for naturalizing around bulbs
What doesn’t
- Not suitable for areas with foot traffic
- Taller profile limits use as a true ground cover mat
- Requires reseeding for persistent growth
5. Marde Ross & Company Creeping Daisy Seeds
This seed packet contains 6,000 Creeping Daisy seeds, producing plants with white petals and yellow centers. They grow 6 to 12 inches tall and form a spreading mat approximately 18 inches wide. These daisies prefer full sun and bloom from mid-summer to fall, creating a cheerful, low-maintenance ground cover for meadows and flowerbeds.
The seeds are non-GMO and neonicotinoid-free, and the product is specifically labeled as pet-friendly. The plants are annuals, meaning they complete their life cycle in one season, but they self-sow readily in favorable conditions. Sow the seeds directly onto garden soil in spring for summer blooms.
In comparison to Blue Star Creeper, Creeping Daisy has a taller growth habit and does not tolerate foot traffic. It is best used as a visual ground cover in open spaces rather than between stepping stones. The white daisies offer a contrasting aesthetic to blue blooms, appealing to gardeners who want a classic, bright display.
What works
- Pet-friendly labeling offers peace of mind
- Forms a wide, spreading mat in full sun
- Low seed cost for a large area
- Blooms well throughout summer and into fall
What doesn’t
- Annual plant requires reseeding each year
- Does not tolerate any foot traffic
- Requires full sun, not shade-adaptable
Hardware & Specs Guide
Mature Height and Spread
For ground covers used in walkways or rock gardens, a mature height of 3 inches or less is ideal. This allows the plant to sit flush with paving stones and avoid being crushed. Spread potential—how wide a single plant will grow—determines planting density. Blue Star Creeper typically spreads 18 inches, meaning you can space plants about 12-15 inches apart for full coverage in one season.
USDA Hardiness Zones
Knowing your zone is essential for perennial survival. Blue Star Creeper is reliably hardy in zones 5 through 10. If you live in a colder zone (3 or 4), you may need to treat it as an annual or choose a hardier alternative. Always check the zone range before purchasing to avoid winter loss.
Sunlight Requirements
Most versatile ground covers perform best in full sun to partial shade. Full sun means at least 6 hours of direct sunlight daily. If your planting site is shaded by trees or buildings, you need a plant that specifically tolerates partial shade. Blue Star Creeper and Forget Me Nots both handle partial shade well, while Creeping Daisy requires full sun.
Foot Traffic Tolerance
Not all ground covers are created equal when it comes to walking on them. The key is a dense, low-growing mat with flexible stems that bounce back after pressure. Plants with upright or brittle stems will develop bare patches. Blue Star Creeper and Creeping Thyme are the two options in this list that can handle regular foot traffic without damage.
