Interested in receiving seeds from SPI for your international humanitarian work? We provide seeds for about 25 types of worldwide-common horticultural vegetables, many featuring both open-pollinated and hybrid choices. We select seed varieties that have wide adaptation to stress conditions such as disease, heat, and limited soil fertility. SPI offers no GMO seed.
Our seed collection is tested to maintain germination at 80-85% or higher at least once a year. We recommend simple germination testing upon receipt and/or after any further storage period.
We continually assess our inventory to ensure quality. As a result, the catalog may have inaccuracies resulting from seed substitutions, additions, or depletions. If something you have selected is unavailable, we will contact you to discuss substitutions.
The seed catalog and order form below will provide answers to other frequently-asked questions, and we encourage you to browse our website for more information about how we work. You are welcome to contact us with any questions in the meantime. Thank you!
