We are amending the regulations governing the importation of cut flowers to remove requirements for the importation of specific types of cut flowers from the regulations, and to list them in the USDA Cut Flowers and Greenery Import Manual instead. Updates to these requirements would occur through notices published in the Federal Register, rather than rulemaking. We are also removing entirely any restrictions on the importation of cut flowers of the genera Chrysanthemum, Leucanthemella, and Nipponanthemum from countries in which chrysanthemum white rust (Puccinia horiana P. Henn., CWR) is known to exist.
