While keen gardeners could each stockpile their own seeds for future use, this approach is limited because:
• Often seeds need to be germinated the next season to keep them viable, and as individual gardeners we have limited space
• We risk climatic or pest events destroying an individuals seed stock

So, we think working together we can better ensure the survival of a variety of self-fertile seeds that have been carefully nurtured for generations, which grow well in our climate.
