Seedball Oddballs (£3.50 Delivery)

These seed balls are made available from the London National Park City Seedbank for Schools, donated by everyone who joined in the Wildflowers for Londoners crowdfunding campaign run in Spring last year.

For every seed ball purchased during this campaign, one seed ball ‘oddball’ has been donated to the SeedBank for Schools to help lots more people celebrate the launch of London as a National Park City during the National Park City Festival, 20 – 28th July 2019.

As a result we have a total of 203 bags of oddballs to give away to schools for only a £3.50 postage and packaging fee.

Each bag will contain approximately 300 wildflower oddballs – great for creating a mini meadow an area of approximately 15-18 m2. Your seed balls will arrive in all manner of shapes and sizes – but they will work just as perfectly!

In sowing these around your school you will become one of the first National Park City Makers, demonstrating how small actions taken by lots of people, can transform our urban landscape. Every young Londoner can be part of making London greener, healthier and wilder 🙂

The wildflower seeds included will be a random mixture from all of our Seedball varieties (every species is inlcuded on the RHS Perfect for Pollinators list). Please be aware that there is a small chance of Foxglove growing (included in our Bee Mix and Beetle Mix), which is toxic if consumed.

The £3.50 price shown is to cover postage and packaging costs – at check-out you will not be charged any extra for shipping unless you add further items to your basket. Delivery will be within 7-10 working days 🙂

As we have a limited number of bags to give-away, we are unfortunalty only able to offer 1 bag per school or group at this time. For how best to use the seed balls, we will provide an information with your delivery and see also out FAQ page. For any questions about the campaign please contact

Thanks so much ! And please do share any stories and pics of your wildflower patches with #NationalParkCity.

What are Seedballs? How do they work?

What is a Seedball?

A ball made from seeds, clay, peat-free compost and chili powder.

Why use Seedballs?

The ball prevents the seeds from being a tasty lunch for birds and insects, thereby increasing the chances of your flowers growing. Plus they’re super easy to use, no digging and no expert knowledge needed!

What's in the tin?

There are 20 balls in each tin, and around 30 seeds per ball.

How do I use Seedballs?

Throw onto soil or compost in a garden bed or planter in Spring or Autumn, leaving at least 10cm between each ball. Your Seedball has everything it needs to grow and, once the ball becomes moist and the temperature is right, your seeds will germinate!

What area will my Seedballs cover?

We would usually advise 20 seed balls per square metre, or 3-5 seed balls for a 35cm container.


All seed is responsibly sourced in the UK from Flora Locale accredited suppliers, we only ever use peat-free compost and our steel tins are manufactured in London (with the help of a solar farm on the factory roof).

See our FAQ page for our full guide to growing wildflowers from Seedball.
