The U.S. federal organic standard, which flowers can meet.
Organic flowers have a special place in my story. In 2002 Organic Bouquet brought what it called the world's first commercial crop of certified organic roses to market, grown in Ecuador and certified by a USDA-accredited agency. I later led that company.
The USDA National Organic Program is the federal standard for anything sold as organic in the United States, including flowers. It governs how a crop is grown: which substances are allowed and prohibited, how land is managed, and what records must be kept. A product that hasn't been certified by a USDA-accredited certifying agent can't carry the USDA Organic seal.
The USDA doesn't inspect farms itself. It accredits certifying agents, domestic and foreign, who inspect farms and handlers and issue the certificates. You can look up a certified operation in the USDA's Organic Integrity Database.
Organic is a growing method, and a good one. But it says nothing about whether workers were paid a fair wage or went home safe, and an allowed organic input can still be harmful if it's mishandled. That's why I tell people organic is a start, not the finish. Read why.
