Seeds Prohibited Entry into the U.S.
by botanical name
Click above by letter to go to the linked chart of restricted plant names.
The above alphabet links to plant names for seeds that are restricted from entering the United States from outside the country. Some are considered invasive pests, some are endangered species, some require special treatments, and others are restricted until a pest risk assessment (PRA) can be performed (this is a literature search). If you are sending seeds to the U.S., check this list first to see whether any cannot enter the U.S. The list is arranged alphabetically by Botanical Name; "spp" means that all species in that genus may not be imported.
All information has been extracted from the USDA-APHIS-PPQ Plants for Planting Manual. Please check that web page for the most up-to-date listing. From the Table of Contents, click on Chapter 6 - Lists of Plants for Planting and search for the particular taxon in the alphabetical list. Use the alphabet bar on the right for easier navigation.
Key to Authority abbreviations:
CITES = see the Checklist of CITES Species website Use the search box and enter seed name to find out whether the taxon is CITES I (no seeds allowed) or CITES II or CITES III (seeds might be allowed).

Or check this pdf abridged CITES list for just the plants.
ESA-E = Cannot be imported; refer to the Endangered Species Act for Flowering Plants and Non-Flowering Plants.
ESA-T = Endangered Species Act-listed as Threatened; allows seeds from cultivated plants; packet must be labeled "Seeds of Cultivated Origin."
FSA = Federal Seed Act covers agricultural and vegetable seeds, which may have special restrictions and treatment requirements.
