How To Choose The Best Flowers For Mosquito Repellent
Not every fragrant bloom repels mosquitoes. To get the most out of your planting, focus on three core factors: active compounds, growth habit, and care requirements. Below I break down what matters most.
Active Compounds That Drive Mosquitoes Away
The repellent power of these plants comes from essential oils like citronellal, geraniol, and linalool. Plants with a strong, lemony or minty scent generally produce higher concentrations of these compounds. Lemongrass, citronella geranium, and lemon balm are top performers. Lantana also contains compounds that mosquitoes find unpleasant, though its scent is more floral.
Growth Habit and Placement
To create a protective barrier, choose plants that spread or grow bushy. Clumping lemongrass works well as a border, while lantana and lemon balm fill gaps quickly. Place these flowers near seating areas, along walkways, and around patio edges. Remember that the scent must be released—brushing against leaves or gentle breezes activate the repellent effect.
Care and Longevity
Most mosquito‑repelling plants prefer full sun and well‑drained soil. Some are perennials in warm climates but treated as annuals in colder zones. Check your USDA zone before buying. Lemon balm is hardy to zone 5, while lantana thrives in zones 9+. Citronella geranium can be grown indoors if needed. Regular watering and occasional pruning keep the plants healthy and productive.

In‑Depth Reviews
1. Citronella Geranium (2‑Pack) – CitronellaKing
This pair of citronella geraniums (Pelargonium citrosum) arrives fully rooted in 4‑inch nursery pots, each plant at least 6 inches tall. They emit a pleasant lemony aroma that mosquitoes avoid, making them a popular choice for patios, decks, and kitchen gardens. The occasional pink blossoms add a soft touch of color.
These plants are versatile—they thrive in containers or in the ground and can even overwinter indoors in colder climates. The protective casing used during shipping ensures healthy arrival, and the plants establish quickly when given full sun and moderate water. The growth habit is compact but can become leggy without occasional pinching.
Many gardeners report noticeable reductions in mosquito activity near these geraniums, especially when leaves are brushed, releasing the citronellal oil. They are deer‑resistant and attract pollinators, adding ecological value. For a balanced mix of beauty, scent, and practicality, this two‑pack is a standout.
What works
- Strong, pleasant lemony scent
- Can be grown indoors in winter
- Deer and pest resistant
- Arrives well‑packaged and healthy
What doesn’t
- May require pruning to stay bushy
- Not as rugged as perennial species in very hot zones
2. Lemon Balm (4‑Pack) – Bonnie Plants
Lemon balm (Melissa officinalis) is a classic herb with a strong lemony fragrance that mosquitoes dislike. This pack from Bonnie Plants includes four healthy plants ready for your garden or containers. It is a perennial in zones 5‑9, returning year after year with minimal effort.
The leaves can be used fresh or dried for teas, salads, and desserts, giving you a dual‑purpose plant. Lemon balm grows best in partial shade and moist, well‑drained soil, spreading readily to form a dense clump. Regular harvesting encourages bushier growth and keeps the scent production high.
Gardeners appreciate its reliability and resilience—it tolerates poor soil and even some shade. However, be aware that it can become invasive if not contained; planting in pots or using root barriers is recommended. For those who want a low‑maintenance, edible repellent, this is a top choice.
What works
- Excellent lemony flavor for cooking
- Hardy perennial returns each year
- Grows well in partial shade
- Easy to propagate from cuttings
What doesn’t
- Can spread aggressively in garden beds
- Repellent effect is milder than citronella geranium
3. Lantana Camara (2 Plants) – Clovers Garden
Lantana camara is a sun‑loving perennial often used as a natural mosquito repellent. This pack from Clovers Garden provides two large, non‑GMO plants in 4‑inch pots, each 4‑8 inches tall. The flowers come in assorted bright colors and attract butterflies and hummingbirds while deterring mosquitoes.
These plants are grown in the Midwest with 10x root development, making them strong from the start. They thrive in containers, hanging baskets, or garden beds across all US zones (treated as annual in colder areas). The scent is not strongly lemony but contains compounds that mosquitoes avoid.
Gardeners love the vibrant, long‑blooming display and the buzz of beneficial visitors. Lantana is drought‑tolerant once established and needs full sun. Its only downsides are potential invasiveness in frost‑free regions and mild skin irritation for some people. For a colorful, low‑cost barrier, it’s hard to beat.
What works
- Vibrant, long‑lasting blooms
- Attracts butterflies and hummingbirds
- Heat and drought tolerant
- Affordable price for two established plants
What doesn’t
- Can be invasive in warm climates
- Leaves may cause skin irritation in sensitive individuals
4. Citronella Geranium (6‑Pack) – Soil Sunrise
This six‑pack of citronella geraniums from Soil Sunrise is ideal for gardeners wanting to cover larger areas. Each plant is GMO‑free and arrives in a nursery pot, ready to grow into a full, bushy form up to 24 inches tall and 12‑18 inches wide. The signature lemony scent is released when leaves are brushed.
These plants are perfect for creating a border around a patio or lining a walkway. They also work well in cottage gardens and mixed container arrangements. A care and feeding guide is included, making it easy even for beginners. The upright growth habit gives a neat, structured look.
Owners report that the quantity is generous for the price and that the plants establish quickly after transplanting. Because they are geraniums, they may need deadheading to prolong blooming. For a large, aromatic barrier that also beautifies, this six‑pack delivers substantial value.
What works
- Large quantity for extensive coverage
- Bushy, upright growth habit
- Includes planting guide
- GMO‑free and non‑toxic
What doesn’t
- Some plants may arrive slightly smaller than advertised
- Requires regular deadheading for best appearance
5. Rooted Lemongrass Stalks (8 Stalks)
Lemongrass (Cymbopogon citratus) is a powerhouse for natural mosquito repellent. This set includes 8 rooted stalks, each 5‑6 inches long, ready to plant directly in the ground or in containers. The stalks contain high levels of citronellal, the same compound found in many commercial repellents.
These plants multiply quickly, forming dense clumps that can create a living screen around your outdoor living areas. Beyond repellency, you can harvest the stalks for teas, soups, and stir‑fries. They are grown using an advanced hydroponic system, ensuring strong, disease‑free roots.
Gardeners appreciate the value—eight plants for a modest investment. Lemongrass prefers full sun and regular water, and it can be overwintered indoors in colder zones. The main limitations are its need for ample space and its sensitivity to frost. For a dual‑purpose, high‑scent repellent, this is a smart entry‑level choice.
What works
- Very strong natural citronella scent
- Edible stalks for cooking
- Multiplies rapidly to fill an area
- Excellent value for 8 plants
What doesn’t
- Not frost‑tolerant; must be brought indoors in cold climates
- Needs ample space and regular watering
Hardware & Specs Guide
Essential Oils & Aroma
The repellent power of these plants comes from volatile organic compounds stored in their leaves. Citronellal (in lemongrass and citronella geranium), geraniol (in geraniums), and linalool (in lemon balm) are the most effective. The stronger the lemony scent, the more repellent the plant tends to be. Crushing a leaf releases the oils, so placing plants where people brush against them boosts protection.
Planting & Care
All of the recommended plants perform best in full sun with well‑drained soil. Most are drought‑tolerant once established, though lemon balm and lemongrass appreciate consistent moisture. Citronella geranium and lantana are heat‑loving. For colder climates, plant in containers to move indoors over winter. Regular pruning and deadheading encourage denser growth and more oil production.
