You can slather on chemicals or light citronella candles that barely cover a tabletop, or you can make a permanent change to your landscape. The right perennial plants create a living barrier that pests avoid, all while adding color, fragrance, and texture to your garden. This guide cuts through the marketing to find the varieties that actually work, evaluating them on scent potency, growth vigor, hardiness, and how quickly they establish.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years studying the intersection of horticulture and pest management, comparing plant chemistry data and analyzing aggregated owner feedback to separate real repellent performance from garden-variety hype.
After testing dozens of specimens and cross-referencing growing requirements with verified buyer experiences, I’ve narrowed the field to five proven options that deliver consistent results. Whether you want borders, containers, or a full defensive perimeter, this review of the best perennial plants that repel mosquitoes will help you pick the right variety for your climate and space.
How To Choose The Best Perennial Plants That Repel Mosquitoes
Not every plant labeled “mosquito repellent” actually produces enough volatile oil to make a difference in your yard. The key is selecting species with high concentrations of citronellal, geraniol, or linalool — the compounds mosquitoes actively avoid. You also need to consider how aggressively the plant spreads, whether it returns reliably in your zone, and how much sunlight your space provides.
Prioritize Scent Compound Density
The mechanism is simple: mosquitoes detect carbon dioxide and body heat, but certain aromatic oils overwhelm their sensory receptors. Lemongrass (Cymbopogon) and lemon balm (Melissa officinalis) contain high levels of citronellal, while citronella geraniums (Pelargonium citronellum) produce geraniol. A plant that smells faintly of lemon when crushed is not the same as one that releases a steady plume of deterrent oil from intact leaves.
Match the Plant to Your Hardiness Zone
A true perennial must survive your winter lows. Lemongrass is only perennial in Zones 8–11, so gardeners in colder regions must treat it as an annual or overwinter it indoors. Lantana returns reliably in Zones 9–11 but can be grown as a tender annual in cooler zones. Lemon balm is more forgiving — it thrives as a perennial in Zones 5–9 and tolerates partial shade. Always check the zone rating before ordering.
Account for Growth Habit and Spread
Some repellent plants become invasive if left unchecked. Lemon balm self-seeds aggressively and can overtake a bed. Lantana spreads as a sprawling shrub that fills gaps beautifully but requires pruning to stay tidy. Lemongrass forms dense clumps that stay contained, making it ideal for borders or large pots. Citronella geraniums grow upright and bushy, topping out around 24 inches, which works well for patio containers.

In‑Depth Reviews
1. Clovers Garden Lantana Camara Flowers – Two Live Plants
Lantana is a workhorse in warm-climate gardens. This pack from Clovers Garden delivers two healthy, 4-to-8-inch plants in 4-inch pots, ready to go straight into the ground or a container. The 10x Root Development claim is backed by a strong start — multiple verified buyers noted the root systems were dense and the plants showed no shock after transplant. The flowers attract butterflies and hummingbirds while the leaves emit a scent that mosquitoes actively avoid, making this a dual-purpose ornamental that earns its space in the landscape.
The “assorted colors” aspect means you won’t know the bloom color until it opens, but the range typically includes yellow, orange, pink, and red. Lantana thrives in full sun and loamy soil with regular watering, but it’s drought-tolerant once established. In Zones 9 and colder, treat it as a tender annual — it will bloom all season but won’t return after a hard freeze. The eco-friendly, recyclable packaging and included Quick Start Planting Guide reduce guesswork for first-time buyers.
Critically, this is not a high-citronellal plant like lemongrass — its repellent effect comes from a combination of volatile compounds in the foliage. You need multiple plants spaced along a patio or entryway to feel the difference. The two-count provides a good start for a small border, but covering a larger area will require multiple packs. The Midwest-grown stock is robust, but shipping during extreme temperatures can stress the plants — one reviewer received wilted specimens that recovered slowly.
What works
- Excellent root development and transplant success
- Attracts beneficial pollinators while repelling mosquitoes
- Packed in sturdy, 100% recyclable materials
What doesn’t
- Only two plants per pack — limited coverage for larger yards
- Not winter-hardy in Zones 8 and below
- Bloom color is random; no choice of variety
2. Bonnie Plants Lemon Balm Live Herb Plants – 4 Pack
Lemon balm is one of the most forgiving repellent perennials you can grow. This 4-pack from Bonnie Plants arrives as rooted, trimmed starts with the characteristic lemon-scented leaves intact. The plant thrives in partial shade, which is rare among mosquito-repelling species — most demand full sun. That makes it a fantastic choice for shaded patios, north-facing beds, or under a tree canopy where other repellents would languish. The scent is immediately recognizable when the leaves are brushed.
The culinary versatility is a bonus: the same leaves that repel mosquitoes can be steeped into tea, chopped into salads, or used to infuse desserts with lemon flavor. The plants grow fast in warm weather — several reviewers reported a 4x size increase within weeks of planting. As a perennial in Zones 5–9, it survives winter dormancy and returns in spring, often spreading via self-seeding. If you want to contain it, grow in a pot rather than open ground.
The main downside is inconsistency in the shipped product. A minority of buyers received tall, leggy stems rather than the compact, bushy plants shown. The packaging uses plastic casing rather than biodegradable wraps, which some eco-conscious gardeners may want to note. Also, lemon balm’s mosquito-repelling power fades quickly once the leaves dry — it works best when the plant is actively growing and the oils are fresh. If you need a plant that works without regular contact, consider lemongrass instead.
What works
- Thrives in partial shade where most repellents fail
- Dual-purpose as a culinary herb and mosquito deterrent
- Hardy perennial in Zones 5–9 with reliable regrowth
What doesn’t
- Can become invasive if not pruned or contained
- Repellent effect drops when leaves are dry
- Some shipments arrived taller than expected
3. 5 Lemongrass Plants – 12 Inches Long, Rooted & Ready to Plant
This is the most potent natural repellent in the group. Lemongrass (Cymbopogon citratus) contains high concentrations of citronellal, the same compound used in commercial mosquito-repelling candles and sprays. THAIPHOON JIRA offers five hydroponically grown stalks, each 12 inches long with established root systems. Multiple buyers confirmed the stalks were thicker than expected and included bonus extras. The roots were well-protected in transit, and many plants showed visible new growth within days of potting.
Hydroponic cultivation means the plants arrive free from soil-borne pests and diseases — a real advantage over bare-root shipments. The stalks can be planted directly in the ground or transferred to containers. In Zones 8–11, they return reliably each year and can reach 3 to 5 feet tall. The dense clump habit makes them excellent for creating a green privacy screen that also repels mosquitoes. The culinary angle is strong too: fresh lemongrass stalks are a staple in Thai and Vietnamese cooking, and they make a fragrant tea.
There are two limitations. First, lemongrass is not cold-hardy — if your winter temperatures drop below 20°F, you must dig up the clump and overwinter it indoors. Second, the roots are delicate during transit. Several reviewers reported that the root ball separated from the stalks during shipping, though the seller provides clear instructions to place the stalks in room-temperature water for about five days to regenerate roots. This salvage step works, but it adds delay and risk for novice gardeners.
What works
- High citronellal content provides strong natural repellency
- Five plants per pack deliver better coverage than two-packs
- Hydroponic cultivation reduces risk of soil-borne issues
What doesn’t
- Not frost-tolerant — must overwinter indoors in cold zones
- Roots may detach in transit, requiring a water recovery period
- Hydroponic plants need gradual acclimation to outdoor conditions
4. Live Healthy Lemongrass – 2 Plants Per Pack – 10″ Tall in 1.5 Quart Pot
For gardeners who want a head start with larger, more mature specimens, this double-pack from The Three Company delivers lemongrass plants in 1.5-quart pots — a significantly larger root zone than the 4-inch pots common in budget offerings. The plants are shipped at 10 inches tall with a 5-inch spread, which means they’re already photosynthesizing actively and will establish faster in the ground. The greenhouse-grown stock is healthy, well-rooted, and ready for immediate transplanting.
The 1.5-quart pot size is the key advantage here. It reduces transplant shock because the root ball is large enough to sustain the plant for weeks without needing immediate nutrient uptake. The variety grows to a mature height of 3 to 5 feet with a 2-foot spread, making it suitable for mass planting along fence lines or as a specimen in a large container. The care instructions recommend full sun, well-draining nitrogen-rich soil, and watering when the top inch of soil dries out — about twice a week outdoors.
The premium price tag buys you size and reliability, but the value proposition weakens if you need to cover a large area. Two plants won’t create a significant repellent barrier on their own — you’d need multiple packs. Also, the quality control on shipping is inconsistent: while many buyers raved about the plants arriving “larger than expected,” a small but notable fraction received mostly dead or sick specimens. This is a risk with any live plant shipment, but it’s disappointing at a premium price point.
What works
- Large 1.5-quart pots mean better root ball and reduced shock
- Greenhouse-grown for robust disease-free stock
- Can reach 5 feet tall for substantial landscape presence
What doesn’t
- Only 2 plants per pack — expensive per-plant cost
- Premium price, but still vulnerable to transit damage
- Not cold-hardy; requires winter protection in Zones 7 and below
5. Live Citronella Geranium Plants – 6-Pack – Pelargonium Citronella
Citronella geraniums are the classic patio-plant repellent, and Soil Sunrise’s 6-pack is an entry-level option that gives you quantity at a reasonable price. Each plant is shipped in a nursery pot with a GMO-free label. The mature height is roughly 24 inches with a 12-to-18-inch spread — compact enough for window boxes, rail planters, or the edges of raised beds. The scent, released when the leaves are brushed or crushed, is unmistakably citronella, and several reviewers noted it filled a small patio space effectively.
These plants prefer summer blooming and moderate watering. They are outdoor-only and will not survive frost, making them annuals in most of the US unless you bring them inside during winter. The bushy upright growth habit is tidy and doesn’t sprawl like lantana, which makes maintenance simple. The included care guide covers feeding, watering frequency, and pruning tips — useful for first-time herb gardeners. The 6-pack count allows you to fill a 2-foot window box with just one purchase.
The weak point is the condition upon arrival. A significant number of reviews report plants arriving dry, wilted, or with leaves covered in soil. In most cases, the plants perked up within 24 hours of watering, but it adds immediate stress that can stunt growth. A few buyers received truly dead specimens. Also, citronella geraniums have the lowest citronellal concentration of the plants on this list — you have to touch or brush against them to release the scent. They work best as a close-proximity repellent for seating areas, not as a wide-area perimeter solution.
What works
- 6 plants per pack provide good coverage for containers and borders
- Compact, bushy habit ideal for window boxes and patios
- Strong classic citronella scent when leaves are touched
What doesn’t
- Often arrives dry and stressed; requires immediate watering
- Repellent effect only activates when leaves are disturbed
- Not frost-tolerant; must be treated as annual in cold zones
Hardware & Specs Guide
Citronellal Content
The primary mosquito-repelling compound in many of these plants. Lemongrass (Cymbopogon) has the highest concentration, typically 70–80% citronellal in its essential oil. Lemon balm contains about 5–10%, meaning you need more plant mass for the same effect. Lantana and citronella geranium rely on a broader mix of volatile compounds including geraniol and linalool. The higher the citronellal percentage, the more passive repellency you get — meaning you don’t have to crush the leaves.
USDA Hardiness Zone
Defines whether a plant returns as a true perennial. Lemon balm is the hardiest of these, thriving in Zones 5–9. Lantana is perennial in Zones 9–11, and lemongrass in Zones 8–11. Citronella geranium is frost-tender and should be treated as an annual or overwintered indoors in Zones 7 and colder. Always check your zone before buying — a plant that dies in winter is an annual, not a perennial.
Mature Spread and Height
Lantana spreads 2 to 4 feet wide, making it a ground cover. Lemongrass forms upright clumps 3 to 5 feet tall with a 2-foot spread. Lemon balm reaches 18 to 24 inches tall and can spread indefinitely via seeds. Citronella geranium tops out at 24 inches tall with a 12-to-18-inch spread. Match the growth habit to your space: clumping plants work well in borders, spreading plants need room to roam.
Sunlight Requirements
Most mosquito-repelling perennials demand full sun (at least 6 hours of direct light). Lemon balm is the exception — it tolerates partial shade well, making it the best choice for north-facing gardens or under deciduous trees. Lantana, lemongrass, and citronella geranium will produce fewer volatile oils and weaker growth in shade. If your only available spot is shady, lemon balm is the clear winner.
