Offshore Greenhouse Certification Program, Eligible Taxa List (Data Table)

Last Modified: April 04, 2024

Unrooted, vegetative cuttings from approved facilities will be eligible when listed in the table that follows. To request the addition of new plant taxa, please contact APHIS at OGCP@usda.gov. Please note that the review process can take several months; please submit new plant taxa well in advance of the shipping season. 

For the purpose of this program, unrooted cuttings are defined as a section of a plant that is removed and used for propagation. While roots are not present, callus tissue (a mass of large, thin-walled, undifferentiated cells that typically form as a precursor to rooting) may be present. For stem cuttings, the stage of the cutting shall be herbaceous or softwood only.

The following are not eligible: 1) Tissue culture/in vitro plantlets; 2) Genetically engineered varieties; 3) Plants for planting having specific requirements in addition to requirements listed in the USDA Plants for Planting Manual, Chapter 2: General Restrictions; and 4) Hybrids and varieties that lack parental information.

Notes:

  1. Participants exporting hybrids and/or varieties must provide parental or source species information to USDA in order to establish eligibility.
  2. Each genus designated with ‘sp.’ (e.g., Abelia sp.) should be interpreted to mean all species and hybrids derived from within the genus are eligible. Identification of the species/hybrid is strongly preferred.
  3. When a taxon is at species level (e.g., Artemisia abrotanum), that specific species must be indicated in the phytosanitary certificate and in the APHIS Core Message Set.   
  4. Some taxon have one or more synonyms. Only one of the synonyms needs to be provided in the phytosanitary certificate. 
  5. Please see comments for plant taxa that are Not Authorized Pending Pest Risk Analysis (NAPPRA) or under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
