Sorry, this part of our campaign has ended now.

If you are here hoping to back the campaign I'm afraid this initial phase has ended. Do please go over and check up our activities at since even if you did not purchase any seed balls this time around there are still things that you can join in with!

If you purchased seed balls they should be with you by 19th April latest. Contact us at if yours have not arrived by then

Thank you for your support! As one of our first National Park City Makers, you are demonstrating how small actions, taken by each Londoner, can transform our urban landscape. Every Londoner can be part of re-greening and re-wilding London.

At the time the crowd-funder campaign ended on 9th April 541 supporters had backed the campaign meaning we had reached a grand total of 2, 910, 906 wildflowers being sown across London.


This spring, we are calling for Londoners to come together and help make London a successful National Park City by sowing 9 million #WildflowersForLondoners - one flower for every Londoner.

You don’t need to know about gardening to help turn London into a greener landscape.

By backing our campaign, you are helping us to show Londoners how easy it is to #getgrowing in our own neighbourhoods and how, through small actions, over time we can transform our urban landscape into a beautiful city of colourful wildflowers returning every year.

#WildflowersForLondoners is led by London National Park City working with Seedball, the award-winning London social enterprise producing wildflower seed balls.

What are seed balls and how do they grow?

They are a simple and easy way to grow wildflowers. The seed balls will contain a mix from several beautiful wildflower species, carefully selected for their ability to thrive in tough, urban areas (just like us Londoners!). They can be sown in random plant pots, window boxes, soil found around the base of trees in pavements, or even in grass. They will provide you with an array of colourful flowers throughout this summer and next, and valuable food sources for pollinators. The balls are coated in clay which protects the seeds while they establish, while fiery chilli powder deters predators, so all you need to do is throw them on the soil, water, and watch them grow.

Buy a Perk, grow your own beauty and invest in the SeedBank For Schools at the same time

Buy seed balls to brighten a neglected corner where you live this summer, and for every seed ball you purchase, Seedball will donate one seed ball to our new London National Park City SeedBank For Schools. These will be distributed free of charge to London schools in early spring 2019, ready for the London National Park City’s launch in summer 2019.

To join in and get seed balls take a look at the perks to the right >

Don’t fancy sowing seeds yourself? Make a donation and Seedball will match your investment 1 for 1

You can also invest in the future of the National Park City by donating money. Your money will equate to a certain number of seed balls which will go into the Seedbank For Schools. £25 will invest 250 seed balls in the SeedBank For Schools, and Seedball will match your donation 1 for 1, making it 500 seed balls! There are 30 seeds in every seed ball, so £25 invests 15,000 seeds in our future. A £45 donation is 1000 seed balls giving a massive 30,000 seeds!

To donate in take a look at the buttons at top right (below, on mobile) >

So what are you waiting for? Get growing now!

This is the perfect time to start sowing your seed balls, you just need to find the perfect spot to do it. Is there a forlorn corner near your home? An abandoned area outside your flat? A boring border in front of your house? You could get your company to turn that dreary area outside your office into an oasis for wildlife, or you could get together with your friends and neighbours and make your street a river of flowers with multiple planted spots along a street. Is there a community garden near you that could benefit, or could you buy some for your local Friends of Park or Friends of A Hospital group for an empty flower bed or around their car parks?

Choose the perk on the right (or on mobile, below) that suits the size of the spot >


  1. I’ve never sown flowers before, is it difficult?
    Seed balls are one of the easiest ways to start sowing wild flowers. Simply scatter them in the area you want them to grow. It really couldn’t be simpler. Try to make sure they are around 10-20 cm apart so they have room to grow. Water them, then just let Mother Nature do her work and in about 12 weeks the first flowers will be visible. Leave them where they are over winter, and in 2019 you will have even more!

  2. When can I scatter?
    This spring as soon as you receive them. Seeds of annuals sown this spring will flower this summer, while perennial plants will sprout and grow but may not flower until the following year. They’ll still look great!

  3. Where can I scatter? Which type should I pick?
    Have a look at our Perks for ideas but let your creativity run free, the more imaginative the better! Seedballs can grow in pots, random boxes, beds and borders. Choose a spot where you can leave them to return next year, and the year after that

    #WildflowersForLondoners seed balls are to be used to bring colour, beauty and wildlife our environment. That is the streets, balconies, gardens, schools, workplaces, community centres and other shared spaces that make up London. They are not to be used in or near where wild plants and flowers are already established. If in any doubt you should enquire with your local wildlife organisations or local council nature conservation officer to ensure there is no risk to important existing wildlife (for example, some derelict-looking brownfield sites host important insects and other wildlife). Full guidance will be distributed with the seed balls.

    When you back the campaign you will be asked whether you want Urban Meadow Mix or Butterfly Mix. Which is best for you depends on the location of your spot, and a little on soil.

    Choose Butterfly Mix if your spot is sunny and has bare soil. Sunny means the spot gets sun for 5+ hours during a summer’s day.

    Choose Urban Meadow Mix if the spot is subject to some pollution (perhaps close to a road) but has bare soil. This mix is also best for sowing amongst grass, though it is a good idea to remove some of the turf and sow in the space created to allow them to establish.

    It doesn’t matter if you’re not sure. That’s a valid answer too, as we will send you a mix which can deal with most situations!

  4. How many seeds are there in each ball and will they all flower? Each seed ball contains 30 seeds, but not all of them will flower. By sowing so many seeds close together you can be certain that some will definitely be successful. After 2 - 7 weeks (depending on rainfall and location) you should be able to see up to 10 sprouts emerging from the surface of each ball. You should see your first flowers from late June. Most of the plants included should hopefully produce lots of blooms.

  5. What do I receive?
    You’ll receive the seed balls in an envelope or bag via post (postage and packaging included!) at the end of the campaign with full instructions on how to make the most of them, and how to share your successes with all Londoners! See below for details of the flowers included.

  6. What will it look like in the end?
    The seed balls contain a mixture of seeds that will flower at different times, at different heights, with different shapes, and different colours so everyone’s spot will be unique. Some plants may not flower in the first year but will flower the following year, if you let nature take its course.

  7. What is an annual? What is a perennial?
    Annuals grow faster and flower earlier but die at the end of the year. They often self-seed and their offspring return to bring joy the next year. Perennials grow more slowly initially, but the plants survive through the winter and keep coming back every year. In our seed balls cornflowers are an example of annuals, and red campions examples of perennials.

  8. I don’t have anywhere to plant, can I still help?
    Of course, you can simply make a donation to the SeedBank For Schools knowing that in spring 2019 schools across London will be using the seeds to get their children involved in “seed balling” and bringing life to London. For every seed ball that you donate, Seedball will match your investment! If you donate £45 the SeedBank For Schools will receive 500 seed balls paid for by you, plus 500 donated 1 for 1 by Seedball!

  9. We’re a group, how can we get involved?
    You could perhaps club together and order a larger number of seed balls for an event or project where you can reach out to your community. Setting up a prepared area and then inviting people to come a “seed balling” event is a great engagement activity. We’ll be sharing guides on projects which have successfully used this approach.

  10. Are the seeds native wildflowers?
    The seeds used in the seed balls are sourced from UK based Flora Locale accredited suppliers. Such suppliers follow a code of practice that seed is native and that the flora has been collected or grown without damaging wild plants. Flora Locale was originally setup by Botanical Society of the British Isles (BSBI), The Royal Society for Nature Conservation (RSNC), Department of the Environment, Royal Botanic Gardens (Kew), Plantlife and the seed industry. You can read about how Seedball care for our world on their sustainability page.

  11. What flowers are included?
    What flowers you will get depends on the seed ball mix you choose:
    Butterfly Mix - Great for a sunny spot, with more flowers sooner, but coming again next year. Contains Chamomile, Cornflower, Corn marigold, Forget-me-not, Musk mallow, Night-flowering catchfly, Purple loosestrife, Red campion and Yarrow
    Urban Meadow Mix - Especially designed for challenging places with fewer flowers this year to allow for even more flowers next year. Contains Common toadflax, Cornflower, Cowslip, Meadow cranesbill, Musk mallow, Oxeye daisy and Red campion.

  12. What is a pollinator?
    Bees (bumblebees, honey bees and solitary bees) are the principal pollinators of flowering plants and are crucial for food production. In the UK, bee pollination services contribute an estimated £1.8 billion per year to the UK economy. Yet their disappearance is a very real threat. A major factor causing the bee's decline is the loss of countryside wildflowers which they rely on for food. Hoverflies, some moths, and butterflies also pollinate flowers, vegetables and fruit. Sadly, three-quarters of British butterflies are in decline. The best thing you can do to help all pollinators is to plant native flowers such as those included in our seed balls.

  13. I'm outside London, can I still take part?
    Of course! You can still purchase one of the seed ball perks and they will be sent to you to use wherever you live. You could simply make a donation too. Just choose the option which suits you best over on the right (or below on mobile)

  14. What personal information do you need?
    We will need your email address and your postal address. These details will be shared with Seedball to allow them to send you your seed balls. Neither London National Park City, National Park City Foundation nor Seedball will retain your postal address information beyond the end of this campaign. During you order you may choose to be added to London National Park City’s and Seedball’s email newsletters.

  15. How does this Crowdfunder work?
    If we reach our target we will be able to sow 9 million wildflowers for Londoners over 2018-2019 and provide free seeds to London's schools next year. This is not an "all or nothing" campaign. Every donation will be used for good, and perks will be distributed even if the target is not quite reached.
  16. What is the London National Park City?
    The London National Park City is a new kind of national park and a grassroots movement that aims to:
    - Connect more people in London to nature and the outdoors, improving health, well-being and social cohesion.
    - Create more high quality green and blue space, making London over 50% green and blue, delivering improvements for wildlife, people’s enjoyment and an attractive and sustainable environment for visiting, living and working in;
    - Promote the identity of London as the world’s first National Park City, helping residents and visitors to appreciate its value and potential for a rich cultural life anchored in its outdoor heritage.
    - Link people to the national and international family of national parks and other protected areas.

    London National Park City is overseen by the National Park City Foundation, registered charity no. 1173267.
