Zollinger Bio seeds

Family know-how to preserve rare varieties

The best organic seeds for your garden - this has been our mission since 1984, the year Christine and Robert Zollinger set out to save traditional and forgotten varieties. Since then, our offer has grown to a seed catalog of over 450 varieties of vegetables, flowers and herbs.

Our varieties are selected in Switzerland and are perfectly adapted to the climate of our latitudes and to the organic growing methods. We do not use hybrid varieties and all our seeds are non-GMO.

To ensure that gardening is a pleasure for you, we create numerous tutorials, videos and a monthly newsletter full of advice, because plants are our passion! Curious to discover our domain? Then come and visit us on our open house day, the second Saturday of July!

Our bilingual French and German customer service team is always ready to help. Whether you need advice on variety selection, cultivation questions or any other request!
