Bare, muddy patches in your landscape aren’t just an eyesore—they invite weeds and erosion. The right low-growing perennial solves this by knitting together a dense, flowering mat that smothers competition and stabilizes the soil beneath. But with seed counts, bloom periods, and sun requirements varying wildly, choosing the wrong creeper can leave you waiting an entire season for results that never come.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent countless hours cross-referencing germination data, growth rates, and owner-reported establishment success for dozens of creeping perennials to isolate the varieties that deliver the fastest, most reliable coverage.
Whether you need to fill a slope, edge a pathway, or replace thirsty turf, this guide breaks down the top contenders for the best fast growing ground covers based on spread rate, bloom density, and real-world hardiness across diverse growing zones.
How To Choose The Best Fast Growing Ground Covers
Not all fast-spreading ground covers are created equal. A seed packet boasting 8,000 seeds might be coated in a slow-release formula that delays germination, while a live plant plug can quadruple in size in a single season. Your choice hinges on three variables: establishment method, sun exposure, and traffic tolerance.
Seed vs. Live Plant: The Speed Trade-off
Seeds are cheap and you get thousands for the price of a coffee, but germination and early growth can take weeks or months depending on soil temperature and moisture. Live plants, like bare-root plugs or potted starts, cost more upfront but establish roots immediately and often produce visible spread within 30 days. If you need erosion control on a slope by next month, go live. If you have a large area and can wait, seeds win on value.
Sunlight and Soil Moisture Matching
Full-sun varieties like Creeping Thyme or Creeping Daisy scorch in deep shade, while Forget Me Nots bolt in harsh afternoon heat. Check your site’s daily sun hours and match the ground cover’s listed requirement. Equally critical is drainage: most fast-spreading perennials rot in soggy clay, while moisture-loving Creeping Jenny thrives in low, wet spots where other creepers fail.
Traffic Tolerance: The Forgotten Spec
If your ground cover runs between pavers or edges a play area, it needs to handle occasional footfall. Creeping Thyme releases fragrance when stepped on and recovers quickly, while Creeping Daisy stems snap under heavy pressure. For pathways, prioritize varieties with woody stems or a naturally compact growth habit that can rebound from trampling.

In‑Depth Reviews
1. UtopiaSeeds Creeping Thyme Seeds
This variety of creeping thyme (Thymus serpyllum) forms a dense, aromatic mat just 2–4 inches tall, making it the gold standard for between-paver plantings and living lawn alternatives. The packet delivers approximately 8,000 seeds, but what sets this offering apart is the stated USDA zone 4 hardiness—meaning it survives winters that kill lesser creeping perennials. Established plants bloom with clusters of tiny purple flowers from late spring through fall, attracting pollinators throughout the season.
The seeds are uncoated and ready for direct sowing after the last frost, and the brand reports strong germination rates in sandy, well-drained soil with full sun. Owner feedback consistently highlights how quickly this thyme fills gaps once the seedlings establish a secondary root network, typically within 8–10 weeks under consistent moisture.
One trade-off: expect a slower start in heavy clay soil or partial shade, where the mat may remain patchy. For sunny, dry sites with moderate foot traffic, this is the most reliable fast-spreading performer at this price tier.
What works
- Fragrant foliage that releases scent when stepped on
- Exceptional cold hardiness rated to zone 4
- Dense mat suppresses weeds effectively by year two
What doesn’t
- Requires full sun for optimal spread and bloom density
- Struggles in heavy clay without soil amendment
2. Creeping Jenny Live Plant (2-Pack)
Creeping Jenny (Lysimachia nummularia) is the closest thing to instant ground cover you can get from a mail-order plant. This listing ships two live plants in 1-pint pots, each already 4 inches tall with an established root system. Once planted in moist soil, the chartreuse-green foliage spreads aggressively, reaching 18 inches wide per plant by mid-summer.
Unlike seed-based options, there is zero germination lag. Owners report visible runners extending 4–6 inches within the first two weeks in consistently damp soil. This makes it a standout for erosion control on creek banks or rain garden edges where other creepers wash out. It tolerates both full sun and partial shade, though the foliage color remains most vibrant with morning sun.
The major drawback is its vigor—Creeping Jenny can overtake less aggressive neighboring plants if not contained. It performs best in a defined bed or as a spiller over retaining walls. Also, it requires regular watering during dry spells; prolonged drought causes the leaves to brown at the edges.
What works
- Zero germination time—live plugs spread immediately
- Thrives in damp soil where thyme and daisies rot
- Vibrant chartreuse color provides a unique textural contrast
What doesn’t
- Can be invasive if not monitored and trimmed
- Foliage discolors during extended heat waves without irrigation
3. Creeping Thyme Seeds (Marde Ross & Company)
This is the seed-for-value king for anyone blanketing a large sunny area on a tight budget. The pack contains over 8,000 GMO-free creeping thyme seeds, enough to cover roughly 200 square feet when broadcast at the recommended rate. The variety is a dwarf purple-flowering type that reaches 6 inches tall at maturity, slightly taller than the UtopiaSeeds version, which gives it a bit more visual presence in flower beds.
Growers report germination within 14–21 days when surface-sown and kept moist, with the first thin mat appearing by week six. The brand’s reputation as a California nursery since 1985 lends confidence to seed viability, and the seeds are untreated, making them safe for pollinator gardens. It handles moderate foot traffic, making it viable for pathway edging and between stepping stones.
Because this is a seed-start, the initial 3–4 weeks require consistent moisture and weed-free soil—dry spells or competing weeds can significantly delay coverage. For impatient gardeners, the live Creeping Jenny will feel faster, but for pure square-footage-per-dollar, this pack is unbeatable.
What works
- Highest seed count in the lineup for maximum coverage area
- Untreated seeds safe for edible landscape borders
- Proven brand with decades of nursery experience
What doesn’t
- Needs careful weed management during germination phase
- Blooms slightly taller than ideal for low-growing lawn substitute
4. Forget Me Not Seeds (Marde Ross & Company)
Forget Me Nots are a uniquely versatile ground cover because they bloom in partial shade, an environmental niche where thyme and daisies struggle. The sky-blue flowers with yellow centers appear in early spring, providing nectar for bees and butterflies when few other plants are flowering. The 500-seed pack covers roughly 50–75 square feet, and the plants reach 6–12 inches tall with a self-seeding habit that thickens the patch year after year.
The seeds are stored in temperature-controlled conditions to maintain viability, and germination occurs in 10–20 days when sown in moist, well-drained soil. Hardy in zones 3 through 9, this is one of the most adaptable creepers for northern climates. It pairs beautifully with spring bulbs like tulips and daffodils, filling the bare soil between bulb emergence and foliage dieback.
Be aware that Forget Me Nots are biennial or short-lived perennials. After the first bloom cycle, they may die back, relying on self-seeding to renew the patch. This can leave bare gaps in late summer if the soil dries out before the seeds germinate. For consistent year-round coverage, mix them with a longer-lived foliage ground cover like Creeping Jenny.
What works
- Blooms early in partial shade when pollinators need food most
- Self-seeds naturally to maintain coverage with minimal intervention
- Extremely cold hardy down to zone 3
What doesn’t
- Biennial lifecycle means foliage dies back after flowering
- Slower to form a dense mat compared to aggressive creepers
5. Creeping Daisy Seeds (Marde Ross & Company)
Creeping Daisy is a budget-friendly entry-level option for gardeners who want a classic white daisy look without investing in premium seed blends. The packet contains 6,000 seeds, and the plants grow 6–12 inches tall with a spreading mat that reaches about 18 inches wide per plant by mid-summer. The white petals with yellow centers bloom from mid-summer to fall, providing color later in the season when many other ground covers have finished.
This is an annual variety, meaning it completes its lifecycle in one season and must be resown or allowed to self-seed for return the following year. The seeds are non-GMO and neonicotinoid-free, and the product listing specifically notes it is pet friendly, which is a key consideration for households with dogs that might nibble on foliage. Direct sowing onto garden soil in full sun yields the best germination rates.
The primary limitation is the annual lifecycle. While the initial cost is low, needing to purchase and sow new seeds each season reduces the long-term value compared to perennial options like Creeping Thyme. Additionally, the stems are somewhat brittle, so this ground cover is not suitable for areas with even light foot traffic.
What works
- Pet-friendly formulation safe for households with animals
- Late-summer blooms extend color into fall
- Extremely low cost per seed for large-scale coverage
What doesn’t
- Annual lifespan requires annual replanting or natural reseeding
- Stems snap easily under foot traffic—unsuitable for pathways
Hardware & Specs Guide
Mature Height and Spread
This is the single most important spec for ground cover planning. Creeping Thyme stays 2–6 inches tall, forming a dense mat. Forget Me Not grows 6–12 inches tall with a more upright habit. Creeping Jenny spreads horizontally up to 18 inches from a single plant but only reaches 4 inches in height. Always match the mature height to your intended use: low for pathways, taller for flower bed fills.
Seed Count vs. Establishment Rate
Seed count (e.g., 8,000 vs. 500) is a misleading speed metric. High seed counts can compensate for lower germination rates, but live plants or plugs (like Creeping Jenny) establish a visible mat weeks faster than any seed. For fastest coverage within 30 days, invest in live starts. For covering 200+ square feet on a budget, high-count perennial seeds like Creeping Thyme deliver the best long-term value.
