What types of seeds can I send?
Flowers, bushes, trees, vines, ornamental grasses, fruits, tomatoes, vegetables and herbs are all welcome and needed. Seed packages must be labeled. No invasive species please.
I found some very old seed packs in a drawer, can I donate them?
Older seeds have reduced germination rates. We ask that you please do not donate seeds more than three years old.
I don't know if my plants are invasive. What are invasive species?
Invasive species are harmful non-native species, and a serious and costly national problem, often with personal impact.
Is there a website with reliable information where I can learn more?
Yes. Please visit:
Do the seeds I donate need to be hand collected?
No. You may donate hand-collected seeds and/or packaged seeds sold in stores and catalogues.
I don't always sow a full pack of seeds, may I donate seed packs I've already opened and taken some seeds from?
Yes. These are always welcome and are oftentimes shared with youth or adult education classes and/or sent bundled with other packs to large groups and clubs.
I am a new gardener and do not know all the plant names. Can I collect and send seeds from these plants?
Yes, you may. For example, a Mom writes:
My son sprouted marigold seeds in his classroom. He brought the seedlings home and I planted them in my garden. They have grown well and appear to be a mix of marigold plants with different flowers.
I've saved their seeds and I would like to share them with WinterSown but I don't know the variety name. What should I do?
Label the seed packet with a generic description that includes the plant name, their approximate mature height, and a simple description of the flower color(s) and petal count ~ such as single, semi-full, or fully double. If the seeds are from a blend, please also add "blend" to the label. A picture of the flowers can be very helpful but is not required.
