This bizarre French customer habit is driving shop owners crazy
Roses, orchids, lilies, carnations, tulips—some of the most popular flowers gifted on Valentine’s Day are among those most laden with pesticides, according to a report by the environmental organization Agir pour l’environnement. This is crucial information to consider before making a purchase.
They’re beautiful, they smell great, and they always bring joy. Giving flowers is one of the most cherished Valentine’s Day traditions. However, beneath these symbols of love lies a less romantic truth. A February 2026 investigation by Agir pour l’environnement uncovered widespread pesticide contamination in cut flowers, including some chemicals that are now banned in the United States. Here’s how to make informed choices at the florist.
Do you prefer roses, irises, or mimosas? The study examined 27 bunches and bouquets purchased during Valentine’s Day and Mother’s Day last season, from various sales channels. The findings were alarming: 99 different pesticides were detected, with total residue concentrations reaching up to 62 mg/kg of flowers. Among these harmful substances, 46 are not approved for use in the U.S. market, including six neonicotinoids, a type of pesticide known for its impact on human health and the environment.
The study also highlighted the presence of substances that are concerning from a health standpoint. Some are classified as carcinogenic, mutagenic, or toxic to reproduction, while others are toxic through inhalation, skin contact, or ingestion. This chemical mix raises particular concerns for florists who handle these flowers daily, often in enclosed, poorly ventilated spaces. However, not all bouquets are equally contaminated. The results indicated that imported and off-season roses had the highest number of residues, sometimes dozens in a single bouquet. Conversely, locally grown and in-season French flowers generally showed significantly lower contamination, with up to 15 times fewer different substances and much lower concentrations. Some bunches even had no detectable residues.
Beyond the risks to professionals, the issue of consumer exposure also arises, especially with repeated contact with flowers or in indoor environments. The organization also highlighted a lack of traceability regarding the origin of flowers, making it difficult to provide clear information to the public.
In light of these findings, Agir pour l’environnement is urging government authorities to enhance protection for florists. The group also emphasizes that choosing local and seasonal flowers could reduce exposure to pesticides and support more sustainable and health-conscious production practices.
