Chantal Guiraud runs the MGS seed exchange which is a service totally free to MGS members. She renews the list regularly and gives advice on what to sow in each season.

See Seed Workshop at the Home of Chantal Guiraud for advice on how to propagate from seeds.

Seed List - July 2024

Chantal Guiraud would like to thank once again the generous donors who have made it possible to add nearly 30 new species to our seed list. These seeds come from Belgium, France, Greece, Malta, Spain and USA.

How to order seeds 
All MGS members may order 10 packets per year. If you contribute seeds to the exchange then you may order 15 packets per year. There is no cost. Please remember that all members are responsible for complying with their local laws. You may order seed from Chantal at the address below or by emailing her. Do not forget to include your name and address when you request seeds.

Chantal requests “Please remember when you order seeds to give me alternatives to the ten species you are requesting in case stocks of them are exhausted.”

How to send seeds
The seeds should be removed from their pods or protective covering, then placed in paper envelopes (not plastic) and well sealed. On the envelope please write: the donor’s name, the scientific name of the plant, the year and location in which the seed was harvested. Chantal accepts all seeds, though with a preference for those of plants from mediterranean-climate areas.

New European regulations require a phytosanitary certificate for importing seeds coming from non-European Union countries but the contrary is not always true. Requirements may vary depending on the country.

Seed donations should be sent to: 
Chantal Guiraud 
75 rue de la Vieille Poste 
34 000 Montpellier 

Note - The seeds in this list are exchanged between garden lovers, entirely on their own responsibility. In particular the MGS bears no responsibility for accuracy of naming or for germination. This seed exchange is in no way a commercial transaction to which any specific regulations apply. Seed from hybrid plants (cultivars) may produce plants which do not have all the characteristics of the parent plant.
