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.
