What is the Heritage Seed Library?

Find us on social media

Garden Organic's Heritage Seed Library (HSL) aims to conserve vegetable varieties that are not widely available. We are not a gene bank and all of our collection, once we have enough seed, will become available for our members to grow and enjoy. The collection consists of mainly European varieties, including:

  • rare landrace varieties, which are adapted to specific growing conditions.
  • heirloom varieties that have been saved over many generations. These are unique to the Heritage Seed Library catalogue.
  • varieties that have been dropped from popular seed catalogues over the past decade. This occurs for a number of reasons; their lack of popularity with customers, their unsuitability for commercial scale production or simply the prohibitive cost of trialling and National Listing.

How does the Heritage Seed Library work?

The seed library currently holds approximately 800 accessions of open-pollinated1 varieties. These varieties have been donated by HSL members or other members of the public, sourced through past HSL projects such as The Seed Search, or passed to us by seed companies who are no longer maintaining them. Each year, approximately 150 varieties within the collection are chosen for inclusion in the Heritage Seed Library Seed Catalogue. Subscribing HSL members receive the catalogue annually in December, from which they can choose six free packets of seeds.

Who grows the seed?

Seed from the chosen varieties is harvested from vegetables grown by Garden Organic's HSL team at Ryton Gardens and by Seed Guardians. These Guardians are HSL members who have decided to take on the extra responsibility of growing seed for us. They make an extremely important and highly valued contribution to our heritage work, supplying approximately half of the seed available for distribution each year. To find out more about the work of Seed Guardians and how you can become one, see Seed Guardians.

What are the benefits of growing Heritage Seed Library seed?

Whether you are a seasoned gardener or a complete beginner, you can enjoy the benefits of growing vegetable varieties from the seed library. By growing HSL seed, you will be:

  • supporting the conservation of unusual vegetable varieties for future generations
  • increasing biodiversity in your garden
  • able to save your own seeds from one generation to the next, our open-pollinated varieties, unlike F1 hybrids2, will come true-to-type.
  • helping to maintain genetic diversity within vegetable crops, which may be useful to the plant breeders of the future

You can explore the Garden Organic website for tips on growing organically and then get started with our heritage seeds after becoming a member! We also encourage you to save seed from the vegetables you grow for your own use. Advice on how to do this can be found in the Seed Saving Guidelines.

Heritage Seed Library Membership

Garden Organic members can add Heritage Seed Library membership for just £18 a year. In addition to the benefits you receive as a Garden Organic member you will also receive the HSL Seed Catalogue annually in December, with a choice of up to six varieties and a seventh lucky dip variety.

Please note that due to import restrictions we are unable to send seeds to countries outside the EU. Individuals living outside the EU are welcome to join the Heritage Seed Library to support this valuable work but will be unable to order seeds.

  1. open-pollinated - a variety that will breed ‘true to type’ from one generation to the next. The seeds produced will carry their parents’ genetic material and plants grown from them will bear their characteristics. Further information (Wikipedia) ↩︎

  2. F1 hybrid - a variety created by crossing two different parent varieties, both of which contribute genetically to the offspring. Seeds saved from F1 hybrids will not produce a plant with the characteristics of the parent. Further information (Wikipedia) ↩︎
