A garden that fills in over months, not years, changes how you think about outdoor space. Fast growing plants deliver privacy screens, vertical color, and ground coverage so quickly that you see measurable progress between weekends. This guide cuts through the hype to show you which varieties actually earn their reputation.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. After analyzing hundreds of seed packets, live plant shipments, and aggregated feedback from thousands of home gardeners, I know exactly which fast-growing options survive transplant shock and which stall out after a promising start.
Whether you need to hide a fence line or add pollinator-friendly blooms in a single season, choosing the right fast growing plants starts with matching variety to your light and soil conditions rather than chasing the fastest germination claim on the label.
How To Choose The Best Fast Growing Plants
Not every plant that sprouts quickly will reach its advertised height, and not every fast-growing variety thrives in your specific zone. The key is understanding which growth metrics matter for your goal — privacy, flowers, edible harvest, or indoor greenery — and which trade-offs you can live with.
Mature Height vs. Daily Visible Extension
Vines like morning glory push out visible inches of new growth every few days once established, while some perennials spread sideways through underground runners but barely climb. If you need vertical coverage fast, look for twining or tendril-climbing species with documented growth rates of 1 to 2 feet per week in peak season. For ground-level density, choose spreading perennials with rhizome or stolon habits that fill bare soil within 60 days.
Light Requirements Determine Real-World Speed
Full-sun varieties like bee balm will stall in partial shade, reducing their growth rate by half or more. Conversely, prayer plants and spider plants scorch under direct afternoon sun. Check the expected sunlight exposure on the product details — “full sun” means at least six hours of direct light, “indirect bright” means a few feet from a south or west window. Mismatching this single spec is the fastest way to turn a fast grower into a slow struggler.
Seed-Started vs. Live-Transplant Growth Trajectories
Live plants already have a 4-to-8-week head start over seed packets, meaning they reach visible size sooner, but seed-grown plants often develop stronger root systems that sustain faster long-term growth. If you want flowers within 45 days of purchase, a live plant in a quart pot beats a seed packet every time. If you’re covering hundreds of square feet, seeds cost less and the root establishment pays off by mid-season.

In‑Depth Reviews
1. Live Plant, Lemon Lime Maranta Prayer Plant
The Lemon Lime Maranta earns its spot among fast growing plants for indoor spaces because its leaves not only unfurl rapidly under bright indirect light but also fold upward at night — a visible daily growth rhythm that confirms the plant is actively expanding. At 12 to 16 inches tall in a 4-inch nursery pot, this specimen already has a mature root system that drives new leaf production weekly during the growing season.
What makes this prayer plant stand out is the dual benefit of air purification and pet safety. The ASPCA classifies Maranta as non-toxic to cats and dogs, so you can place it on low shelves or tabletops without worry. Its vivid green leaves with yellow veining and dark-green markings provide instant visual impact while the plant continues to spread horizontally from its central crown.
Care is straightforward: water when the top half of the soil feels dry, keep humidity moderate with occasional misting, and avoid direct sun that will bleach the foliage. The Hopewind packaging includes eco-friendly materials and the plant arrives fresh from a California facility. For beginners who want a fast-growing indoor plant that also purifies air and stays safe around pets, this is the most complete package available.
What works
- Visible new leaf growth every 5–7 days under correct light
- Certified non-toxic for homes with cats and dogs
- Natural air purification improves room air quality
- Arrives in a sturdy 4-inch pot ready to display
What doesn’t
- Requires consistently warm temperature above 65°F to maintain growth rate
- Single plant per purchase covers limited visual area compared to multi-pack options
2. Mixed Morning Glory Seeds for Planting – 200 Fresh Seeds
Morning glory seeds from Marde Ross & Company deliver the fastest vertical coverage you can get from a seed packet, germinating in 7 to 14 days and climbing to 8 to 12 feet within a single growing season. The 200-seed count lets you cover an entire fence line or arbor, and the mix of blue, purple, white, and rose trumpet-shaped flowers creates a dense tapestry that attracts hummingbirds and butterflies as soon as the first blooms appear.
The key to success with these seeds is scarification — nicking or soaking the hard seed coat before planting — which dramatically improves germination consistency. Once sprouted, morning glories thrive in full sun with moderate watering and well-drained soil. Hardy in zones 3 through 11, they perform across nearly every US climate, making them one of the most universally reliable fast growing plants for outdoor vertical applications.
These seeds are stored in temperature-controlled refrigeration to maintain viability, and the company has operated as a California nursery since 1985, giving you provenance you can trust. The untreated nature of the seeds means they are GMO-free and suitable for organic gardens. For budget-conscious gardeners who need rapid screening or decorative vine coverage, this seed mix offers the highest growth-to-cost ratio in this comparison.
What works
- Germinates within two weeks and reaches full height in one season
- Large seed count covers substantial fence or trellis area
- Multicolored blooms attract essential pollinators continuously
- Thrives across a wide range of hardiness zones from 3 to 11
What doesn’t
- Seeds require pre-treatment (scarification) for best germination rates
- Annual variety dies back after first frost each year
3. Spider Plant Variety Pack – 4 Live House Plants
The Spider Plant Variety Pack from August Breeze Farm gives you four distinct cultivars — Ocean, Hawaiian, Green, and Bonnie Curly — each with different leaf shapes, variegation patterns, and growth habits, yet all sharing spider plant’s legendary air-purifying capability. Spider plants are among the fastest growing indoor plants, sending out runners (stolons) with baby plantlets within weeks of establishment, which you can propagate into new pots for free.
These live starter plants arrive ready to grow in sandy soil with full sun exposure, though they tolerate medium indirect light well. The drought-tolerant nature of spider plants means you can miss a watering without losing growth momentum, making them one of the most forgiving fast growing plants for beginners or frequent travelers. The mature height reaches 28 inches, and the cascading foliage works beautifully on shelves or in hanging baskets.
The variety pack is GMO-free and cultivated without harmful chemicals, and the four distinct forms create an attractive display even when clustered in the same planter. For home office or living room decoration where you want visual diversity without complicated care, this pack delivers four unique plants that each grow at a reliably fast pace. The year-round blooming period means you may even see small white flowers on mature plants.
What works
- Four different spider plant varieties in one purchase for diverse aesthetics
- Produces stolons and baby plantlets that accelerate propagation
- Highly drought-tolerant, forgiving of irregular watering schedules
- Known for exceptional indoor air purification capabilities
What doesn’t
- Individual plants are starter size and need several weeks to reach full visual density
- Some varieties may have subtle color differences not shown in product images
4. Live Flowering Bee Balm – Balmy Purple (2 Plants Per Pack)
Bee Balm in the Balmy Purple variety delivers rapid expansion through underground rhizomes, meaning the two plants per pack will spread to 3 to 4 feet wide within their first full growing season. This live perennial from Deep Roots and The Three Company ships fresh from greenhouse to customer, bypassing the slow seed-starting phase and giving you immediate visible growth in moist, well-draining soil under full sunlight.
The purple blooms are a top-tier attractant for butterflies, bees, and hummingbirds, and because bee balm is a member of the mint family, it grows vigorously enough to outcompete many weeds once established. Watering every 1 to 2 weeks with deep soaking at the base encourages roots to reach deeper soil layers, which in turn supports faster top growth and more abundant flowering from midsummer through early fall.
The expected height of 2 to 4 feet makes bee balm ideal for the middle or back of pollinator garden beds, and its historical use for topical bee sting relief adds a fun conversation piece. For gardeners who want fast growing plants that provide both dramatic color and ecosystem support, this two-pack establishes a long-lived perennial patch that returns larger each year without needing replanting.
What works
- Rhizome spread reaches 3–4 feet wide within one growing season
- Two live plants per pack provide immediate garden presence
- Deep purple blooms attract butterflies and hummingbirds reliably
- Perennial nature means it returns and expands each year
What doesn’t
- Requires full sun for optimal growth and flowering density
- Can spread aggressively in rich soil if not divided every few years
5. Bonnie Plants Garden Sage Live Herb Plants – 4 Pack
Garden sage from Bonnie Plants offers one of the fastest returns on investment among culinary herbs because these four live plants are already several weeks old at purchase, meaning you can start harvesting leaves within two to three weeks of planting. The velvety gray-green foliage is the key ingredient in poultry seasoning and turkey stuffing, and the plants produce pretty blue blooms in spring that attract pollinators to your herb garden.
Sage is a woody perennial in zones 5 through 8, meaning these plants come back year after year, expanding into a larger bush each season. They thrive in containers or in-ground herb gardens with regular watering and full sunlight. Each of the four plants in the pack weighs approximately 3 pounds total, giving you substantial root mass and foliage from the start rather than tiny starter plugs that take months to fill out.
The non-GMO certification and Bonnie Plants reputation as a major nursery brand provide confidence in the genetic consistency of the sage. For home cooks who want fast growing plants that simultaneously serve as ornamental garden features and kitchen staples, this four-pack delivers immediate harvest potential and long-term perennial value. Plant them in spring and you will have fresh sage leaves through fall and again the following year.
What works
- Harvest-ready within weeks due to mature live-plant head start
- Four plants per pack create substantial visual and culinary impact
- Perennial nature provides multi-year growth without replanting
- Blue blooms add ornamental value while attracting pollinators
What doesn’t
- Limited to hardiness zones 5 through 8 for perennial overwintering
- Slower growth in partial shade compared to full-sun placement
Hardware & Specs Guide
Germination vs. Mature Growth Rate
Germination speed (days to sprout) and mature growth rate (inches per week after establishment) are two separate metrics. Morning glory seeds sprout in 7–14 days but accelerate to 1–2 feet per week once roots establish. Live perennials like bee balm skip the germination phase entirely but expand laterally through rhizomes at 2–4 inches per week. Always evaluate both metrics against your timeline: if you need coverage in 30 days, buy live plants. If you can wait 60 days, seeds offer more volume for less cost.
Sunlight Exposure Matching
Every fast growing plant in this guide specifies a sunlight requirement — full sun (six-plus hours direct), bright indirect (near a window but not in direct rays), or partial shade (morning sun only). Mismatching light is the single fastest way to cut growth rate in half. Morning glory, bee balm, and sage all require full sun. Prayer plants and spider plants need bright indirect light. Check your growing location before purchasing to ensure the light matches the plant’s need.
