There is something bright and cheering about an area of beautiful wildflowers in bloom, blowing gently in the wind, during the summer months. What begins as a handful of seeds, sprinkled on raked over bare soil, can become a place full of wildlife. This guide on best wildflower seeds UK will help you get started.
You may see bees flying from one red poppy to another, butterflies gently landing on ox-eye daisies, and, if you look closely caterpillars hidden beneath the leaves.
Thinking about starting a wildlife area
If you are thinking about starting a wildlife garden, or seeking an area specifically for pollinators, sowing a packet of mixed wildflower seeds is a simple, effective step towards a wonderful vision of wildflowers in bloom.
This guide explores the best wildflower seeds UK and how to choose one that will support wildlife, and flower across the seasons. However, with patience, some may be self seeding wildflowers and grow again each year.
Why Wildflower Seeds Are Important for Wildlife
A packet of wildflower seeds can change a garden to make it more attractive to butterflies, caterpillars and bees. These wildflower seeds provide food, shelter and a resting places for a variety of pollinators.
Wildflowers provide:
*Nectar for bees and butterflies
*Food plants for caterpillars
*Shelter and resting places for insects
*A mix of fallen seeds later in the year for birds
*Support for overall diversity
Butterflies may visit the garden looking for specific foot plants for their caterpillars. However, in gardens where these plants are not available, butterflies may briefly visit, but will move on, and visit other gardens.

When to Sow Wildflower Seeds in the UK
Timing can make a difference to how well the wildflowers establish.

Autumn sowing enables seeds to experience natural cold. This helps some species germinate successfully.

A simple approach is enough:
*Remove weeds or grass.
*Lightly rake over the surface of the soil.

*Scatter the seeds thinly.
*Press the seeds gently into the soil.
Try to Avoid Common Errors

Expecting flowers immediately.
*Some species take time.

A Few Seed Mixes to Consider
If you are starting out, choosing a suitable seed mix can make things feel easier. There are many options available, and it is a case of finding one that suits your space and the kind of garden you would like to create.
Best General Wildflower Mixes
A reliable choice is the Thompson & Morgan Wild Flower Mixture, which is easily available and easy to establish.
For a lower cost option, a meadow style mix such as Mr Fothergill’s Wildlife Mixture, Mixed can work well. Especially if you are trying a new area in the garden.
Best Bees and Butterfly Mixes
If you aim to support pollinators, a bee & butterfly friendly mix with nectar rich flowers can provide longer feeding throughout the summer months.
Some mixes including the Sylvawood Seeds Bees and Butterflies Wildflower Seed pack available through the RSPB, are designed to support butterflies and bees across the summer months, and are often well reviewed by gardeners.
Alternatively, a Wildflower Bee & Butterfly Meadow Mix Packet is highly recommended for pollinators.
Best Native Wildflower Seed Mixes
For a natural approach, native wildflower mixes can be beneficial for gardens.
These include wildflower species that are suitable for conditions in the UK and can gradually support a wide range of insects over time.
A mixture like the Garden Lawncare Guy UK Native Wild Flower Seeds Mix, mixture can help support a range of insects and create an ecologically balanced garden environment.
Mixed Seed Packs With Grasses
Wildflower seeds mixes can vary, and it’s not always clear what is included.
I’ve had mixed experiences with wildflower seeds. Some mixes can contain lots of different grasses, or a lot of ground cover species, seeds, such as ground ivy and mugwort. Plants that don’t always suit the kind of space I’m trying to create.
In my own garden, I have found that a little bit of control can help. I choose grasses I like and decide where they can be planted. Ivy is in certain areas, such as along a trellis fence rather than within the wildflowers themselves. I have used both grass free and general mixes for my small wildflower area. It’s all about what works best for your space and what you are aiming to create.
Conclusion
You can choose from a variety of wildflowers to suit your space. Your garden does not need to be tidy or perfect or large or small. It can simply become a place for wildlife. A sanctuary for nature – and for you.

A practical note, I’ve found after borage has finished flowering, it can be added to the compost. It can also be steeped in water in an old pillowslip. Three to four weeks later it will have created liquid feed for plants. This is a process you can also use with Stinging Nettles.
