Listing Seeds

You may want to print these instructions (especially if you’re an infrequent computer user) or keep them open in an adjacent window while you set up your first listings.

We are available to add listings for those who are elderly, stewards of large collections, infrequent computer users, disabled, and/ or not fluent in English.  We are also available to help you add your listings.  Contact us for more information.

Choose how, and whether, you want requestors to pay you.

Listing title:
This is the title that will show up in searches and on the listing’s page. Please include the variety name and also the crop type, eg, “Coyote cherry tomato” or “Lemon Gem marigold.”

Our suggested sample prices are meant to cover postage, shipping materials, handling, and costs of production. For online orders, PayPal’s payment processing fee is also included.

$3 for small seeds of annual crops
$4 for large seeds, and seeds of biennial or perennial crops
$10 for tubers, garlic, and scionwood

Description (optional):
Detailed descriptions help requestors figure out what varieties they want to grow. We encourage you to include any information you have that you think would be a factor for a requestor choosing seeds, such as:
– stories from the families and cultures that have tended the variety, and what it’s meant to them.
– any methods you use to keep varieties from crossing, such as isolation distances or hand-pollination
– how the variety has fared in particular conditions on your farm (cold, heat, drought, flooding, etc)
– days to maturity
– harvest window
– height
– growth habit
– flavor
– aroma/ fragrance
– yield
– storability
– size, shape, and color of flowers and fruits
– support needed, such as trellies or cages
– other cultural requirements

(In general, more information is better, but when we create a print edition, long descriptions will be cut off after the first few lines. When we make descriptions show up on multi-listing pages, long descriptions will be cut off there as well.)

Safe Seed Pledge:
GSN does not knowingly allow users to offer GMO or PVP seed. As a lister, it is your responsibility to offer only open-pollinated, non-hybrid, non-GMO seed that you have grown. Please do not offer seed of poisonous, hazardous, or invasive plants.

Legalities: You are responsible for following any applicable seed testing and labeling laws. If you charge for the seeds you send out, and especially if you depend on income from seed sales, we encourage you to label all your packets with your name and address, the percentage germination, the date tested — or date packed if stored in a freezer — and the lot number, in order to ensure that you do not suffer fines or confiscation. However, these laws are rarely applied to very small-scale or free exchange of seeds. Furthermore, people around the world are pushing back against restrictive application of seed laws.
