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 2025
I would like to thank all our generous donors, David Tivol Christine Daniels, Patricia Hamilton, Viktor Hans Lutz John, Gabriele Luea and all the others that I cannot name here, due to lack of space. Without them, we would not be able to offer such a large choice of species: 493 different taxa at the moment. More than 100 are collected in my own garden. But, as I am going to move and live in a flat with a huge terrace, I will have to grow plants in pots which is very different. And so, I am asking you to be more generous with your donations. Please send me any seeds, free from any pods or debris. I don’t need many of the same species as I have to throw them after 3 years. This call for donations only concerns european members as sending seeds from non european countries needs Phytosanitary certificate.
In addition to the seeds listed below, Château Pérouse has generously made available to MGS members its Index seminum containing around 1600 taxa. Seeds from this list should be ordered as usual through Chantal, as part of the quota per member of 10 packets per year.
Among the most popular seeds in 2024, here is the hit parade:
Many of you have questions about the new laws on importing and exporting seeds. I would like to clarify this because it is not a simple matter. The biggest change is that importing seeds from countries outside European Union (EU) is no longer allowed into the EU, unless a phytosanitary certificate is provided. It should be noted that a phytosanitary certificate costs money. Finally, and I regret this very much, we are not allowed to send seeds to Australia and Japan.
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. 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.”
Please remember that all members are responsible for complying with their local laws.
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.
Seed donations should be sent to

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.
