Flowers in Pots That Help Keep Mosquitoes Away

There’s something about a warm evening in Australia that feels almost perfect - until the mosquitoes arrive.

Lately, while researching plants for pots and small garden spaces, I discovered that some of the most beautiful flowering plants also happen to be ones mosquitoes dislike.

The idea appeals to me enormously. Instead of spraying chemicals or lighting coils, you can simply surround your outdoor space with living plants that quietly do the work.

What I particularly like about this approach is that it suits almost any home.

Whether someone has a sprawling backyard in regional NSW or a small patio in suburbia, large pots filled with the right plants can become both decoration and a gentle mosquito deterrent.

It feels like one of those small natural solutions that simply makes sense.

I like to research before making decisions, so I investigated the top flowers that keep mosquitoes away. Here is what I found.

Flowers that keep mosquitoes away

Lavender

Lavender is probably the most famous mosquito-repelling plant, and fortunately, it also happens to be one of the easiest to grow in pots.

The scent we find calming is something mosquitoes strongly dislike. Lavender contains natural oils such as linalool, which are known to repel insects.

What I like about lavender in particular is how well it suits the Australian climate. It enjoys sunshine and dry soil, which makes it perfect for large terracotta pots on patios or verandahs.

I can imagine several pots placed near outdoor seating areas, where brushing past the plant releases that familiar calming scent.

Marigolds

Marigolds are cheerful, bright, and surprisingly effective at discouraging mosquitoes.

They contain pyrethrum, a compound that is commonly used in natural insect repellents.

While the plant itself doesn’t eliminate mosquitoes completely, placing them around seating areas can help discourage them from lingering.

Another benefit is that marigolds thrive in pots and flower for a long time during the warmer months.

They’re also wonderfully forgiving plants — perfect for those of us who enjoy gardening but sometimes forget to water on the exact right day.

Scented Geraniums (Citronella Geranium)

Often called the “mosquito plant,” citronella geraniums have a strong lemon-like fragrance that insects dislike.

They’re excellent for large pots near doors or outdoor dining areas, where the scent is released when the leaves are brushed or gently crushed.

One thing I discovered while reading about them is that their mosquito-repelling ability works best when the scent is released naturally - so placing them where people walk past is ideal.

They also produce delicate pink flowers, which makes them both functional and pretty.

Petunias

Petunias are often grown simply for their colour, but they also have mild insect-repelling properties.

They are sometimes referred to as a “natural pesticide flower” because they can deter insects such as aphids, beetles, and some mosquitoes.

What makes them appealing is their abundance of colour.

A large pot filled with cascading petunias can brighten a verandah while quietly helping reduce insects around the area.

For those of us who enjoy a cottage-style garden feeling, petunias fit beautifully.

Chrysanthemums

Chrysanthemums contain pyrethrins, a natural compound used in many insect repellents.

Because of this, they’re considered one of the stronger insect-repelling plants.

They grow well in pots and provide generous flowers through autumn, which is a time mosquitoes can still linger in many parts of NSW.

A few large pots of chrysanthemums near outdoor areas can add both colour and function.

A Small Pot Garden Strategy

From what I’ve been reading, the most effective approach isn’t relying on a single plant, but creating small clusters of pots.

For example:

• Lavender near seating areas

• Citronella geraniums near doorways

• Marigolds and petunias around patio edges

Together, they form a small scented barrier around the space.

And perhaps that’s the real charm of it — instead of trying to eliminate nature, we simply garden alongside it more thoughtfully.

A Quiet Reflection

I often find that the most satisfying ideas in gardening are the simple ones.

Planting flowers to discourage mosquitoes feels almost old-fashioned in a way - the sort of thing people might have done long before sprays and electric traps existed.

It reminds me that sometimes the answer isn’t more technology or more chemicals.

Sometimes it’s simply a few well-chosen plants in a sunlit pot.

And perhaps that is part of the joy of growing things - the quiet sense that nature already holds many of the solutions we are searching for.
