Seed Requests

DELEP distributes samples of seeds subject to availability, to individuals and organizations in the U.S. and overseas. DELEP's Index Seminum includes a listing of seed availability and instructions for requesting seeds.

Send questions and seed requests to or write:

          Seed Bank
          Desert Legume Program
          2120 East Allen Road
          Tucson, AZ 85719

Seeds may also be requested through the USDA-ARS GRIN (select "Desert Legume Program – DLEG" as the Repository under Advanced Search) For international requests, please note that due to costs and logistics, we are unable to provide phytosanitary certificates. If a phytosanitary certificate is required by your government, please submit your request through the USDA-ARS GRIN website. We ask that requests for seeds be limited to about 20 accessions per year though we are able to make exceptions. Due to a major loss of funding in 2018, we are requesting a donation of U.S. $10.00 per accession.
