Companion Planting: Flowers, Vegetables & Herbs That Grow Well Together

May 21, 2026

One of the nicest things about companion planting is the way it helps create a garden that feels healthy, balanced, and full of life.

Flowers bring in pollinators, herbs add scent and diversity, and a wider mix of plants often helps keep pests from settling too heavily in one area. The result is usually a more productive garden overall — with stronger crops, better pollination, and a space that feels vibrant throughout the growing season.

Companion planting doesn’t need to be complicated, either. It’s not about strict rules or perfectly planned layouts, but simply choosing plants that naturally support each other when grown close together.

Sometimes that means attracting bees to help pollinate crops. Sometimes it’s confusing pests with scent, improving airflow between plants, or making better use of the space you have. And often, it simply creates the kind of garden where everything seems to grow a little better.

Why Companion Planting Works

A mixed garden naturally attracts more life. Bees and hoverflies move between flowers and crops, herbs release scent into the air, and a wider variety of plants helps create a more balanced growing space overall.

That balance is often what keeps gardens healthy. You’re less likely to end up with large areas of one crop attracting pests, and more likely to see pollinators regularly moving through the garden - particularly during the peak growing months. It also makes the space itself feel softer and more abundant. Productive gardens don’t need to look rigid or overly practical.

Vegetables and Flowers That Grow Well Together

Tomatoes + Basil + Marigolds

This is one of the classic combinations, and for good reason. Basil grows happily in similar conditions to tomatoes, while marigolds attract pollinators and are often thought to help deter certain pests in the greenhouse.

Together, they create a growing space that feels productive but still colourful and relaxed.

Courgettes + Cosmos

Courgettes rely heavily on pollination to produce good harvests. Cosmos are excellent at attracting bees and other pollinators into the vegetable patch, which can help improve fruit set throughout summer. They also add height and movement around larger vegetable plants.

Brassicas + Nasturtiums + Dill

Kale, cabbage, and broccoli can often attract aphids and cabbage white butterflies. Nasturtiums are commonly grown nearby as a sacrificial plant, helping draw pests away from crops, while dill attracts hoverflies and beneficial insects that feed on aphids.

Beans + Sweet Peas

Climbing beans and sweet peas work beautifully together. Both enjoy similar growing conditions and support structures, and sweet peas help bring pollinators into the area once flowering begins. It’s also one of the simplest ways to add colour into a productive space.

Carrots + Chives

Chives are often grown near carrots because their strong scent may help confuse carrot fly. They’re compact, useful in the kitchen, and produce flowers that pollinators love if left to bloom.

Lettuce + Calendula

Calendula is one of the easiest companion flowers to grow. Its flowers attract pollinators throughout summer, while the plants themselves fit neatly around crops, like lettuce, without taking up too much room.

The bright flowers also help break up rows of leafy greens visually, making the garden feel more varied and lively.

Herbs Are Some of the Best Companion Plants

Herbs quietly do a lot of work in the garden. Many attract pollinators once they flower, while others release strong scents that may help disrupt pests searching for crops.

Some of the easiest herbs to weave into vegetable beds include:

• Basil near tomatoes
• Dill near brassicas
• Chives near carrots
• Parsley near asparagus
• Mint near seating areas or pathways (best kept in pots)
• Coriander throughout the veg patch to attract hoverflies

Letting a few herbs flower often brings far more pollinator activity into the garden than people expect.

Starting Everything Together

One of the easiest ways to plan companion planting is to start flowers, herbs, and vegetables together in spring. That way, everything is ready to plant out at a similar stage once the weather warms up.

This is something we tend to do with Soil Blockers - sowing flowers, herbs, and vegetables side by side in trays so everything stays organised while seedlings are small. It’s especially useful once the season gets busy and you’ve suddenly got multiple batches of seedlings growing on at once.

A Garden That Feels Alive

One of the real benefits of companion planting is that it encourages a more natural rhythm in the garden. Flowers blooming among vegetables, herbs going to flower for pollinators, bees moving between crops - it all creates a space that feels active and balanced.

And more often than not, those are the gardens that end up producing the most rewarding harvests.
