Introducing the Heritage Seed Library

How the Heritage Seed Library works

The seed library holds over 800 varieties of seeds, including rare landrace varieties adapted to specific growing conditions, heirloom varieties saved over generations and varieties no longer available to buy.
Why we grow heritage seeds

The Heritage Seed Library is a vital resource to connect people with seed, keep our heritage alive and increase biodiversity.
This year’s Heritage Seed Library seed trials

This year at Ryton, we are trialling four re-discovered heritage varieties to check for health, cross-pollination, and description.

Get involved with HSL
