Best Flowers to Grow on an Allotment: 25 Beautiful and Useful Flowers

Growing flowers on an allotment is one of the best ways to make your vegetable-growing space more colourful, attractive and welcoming to wildlife.

Although allotments are traditionally associated with growing vegetables, fruit and herbs, flowers can play an important role in creating a healthy and productive growing environment.

Many flowers attract bees, butterflies, hoverflies and other beneficial insects.

These insects can help pollinate crops and, in some cases, reduce populations of garden pests.

Flowers can also provide beautiful displays throughout the growing season, from early spring bulbs to colourful summer annuals and late-flowering perennials.

Some varieties are excellent for cutting and bringing indoors.

Others can be grown around vegetable beds, along pathways, beside sheds or in dedicated wildlife areas.

Here at Gardening with Ben, I’ve always enjoyed combining flowers with fruit and vegetable growing.

After many years of allotment gardening, one of the things I particularly appreciate is seeing how much wildlife visits the plot when flowers are blooming.

Sunflowers, calendula, sweet peas, cosmos and many other flowers can transform an ordinary vegetable-growing area into a beautiful and productive space.

And you don’t need to sacrifice an enormous amount of growing space.

Even a few containers or a narrow flower border can make a difference.

In this complete UK allotment gardening guide, we’ll explore 25 of the best flowers to grow on an allotment.

We’ll cover which flowers attract bees, which may support beneficial insects, which are suitable for growing alongside vegetables and which make excellent cut flowers.

We’ll also look at sowing times, planting advice, maintenance, common mistakes and how to create a flower-filled allotment from spring through autumn.

Why Should You Grow Flowers on an Allotment?

Flowers offer several important benefits.

1. Attract Pollinating Insects

Many flowers provide nectar and pollen for bees, butterflies, hoverflies and other insects.

2. Support Vegetable Pollination

Pollinating insects can help improve fruit set in crops such as courgettes, pumpkins, squash and some fruit crops.

3. Encourage Beneficial Insects

Certain flowers attract insects whose larvae or adults feed on garden pests.

4. Add Colour

Flowers make allotments more attractive throughout the year.

5. Provide Cut Flowers

Many varieties are suitable for cutting and displaying indoors.

6. Support Biodiversity

A mixture of flowers can provide resources for different insects.

7. Make Use of Small Spaces

Flowers can be grown in containers, borders and suitable gaps around vegetable beds.

8. Extend the Gardening Season

Early and late-flowering varieties can provide colour beyond the main vegetable-growing season.

Do Flowers Really Help Vegetable Gardens?

Yes, although the benefits depend on the flowers, crops and insects present.

Pollination

Flowers attract pollinating insects.

This can be particularly useful for insect-pollinated vegetables and fruit.

Beneficial Insects

Some flowers provide nectar or pollen for adult hoverflies and parasitic wasps.

Their larvae or offspring may help control pests.

Biodiversity

A greater variety of flowering plants can support a wider range of wildlife.

Important Advice

Companion planting isn’t a guaranteed way to prevent pests.

Growing flowers alongside vegetables can be beneficial, but it doesn’t replace good crop care, pest monitoring or appropriate protection.

Flowers should complement vegetable growing rather than compete excessively for water, nutrients and sunlight.

Do Marigolds Keep Pests Away?

Marigolds are often recommended as companion plants.

However, their benefits are sometimes exaggerated.

What Can Marigolds Do?

They provide flowers for visiting insects.

Some Tagetes species can suppress certain plant-parasitic nematodes under specific growing conditions.

What Can’t They Guarantee?

They don’t reliably repel every garden pest.

They won’t automatically prevent aphids, whitefly or caterpillars.

Scabious

Popular with butterflies.

Echinacea

Provides accessible flowers.
