One of the most enduring spring traditions in the Île-de-France region: every May 1, the streets of Paris and the Île-de-France area don themselves with small bouquets of lily of the valley, those white bells famed as good luck charms. Whether you’re thinking of posing as a lily-of-the-valley seller for a day or heading out to harvest them in the forests of the Île-de-France region, here’s everything you need to know before you dive in this Thursday, May 1, 2026.
This is the question on everyone's lips, and the answer is yes—but with conditions. May 1st is the only day of the year when selling flowers in public spaces is allowed for anyone, without a business license or prior declaration. This exception, however, applies only to lily of the valley, and only on the day itself: neither the day before nor the day after. To sell legally, a few rules apply:
If you fail to comply with these rules, you risk a fine of up to 300 euros, or 600 euros in case of an increase. A well-chosen location, away from competing shops, and you’re in the clear.
For those who prefer a nature-filled outing, a trip to pick wild lily-of-the-valley in the forests of Île-de-France makes for a delightful family excursion. On the eve of May Day, the forest belts are already drawing clammers of lucky bells, armed with a knife and a basket. The National Forestry Office (ONF) reminds that in public forests, family-oriented picking is tolerated but still requires the forest owner’s permission. Before you head out, it’s wise to check with your town hall that no prefectural or municipal decree bans it in your intended area.
The quantity is also restricted: limit to what the hand can hold, roughly 10 to 15 stems per person. Beyond that, the Forestry Code imposes a fine of €135 for abusive harvesting. Remember to cut the stems cleanly with a knife rather than pulling up the entire plants, to allow the plant to regrow next year.
A crucial point not to overlook: lily of the valley is an extremely toxic plant for children, cats, dogs, and many other pets. If ingested, even in small amounts, there are real risks to the heart. If you bring it home, wash everyone’s hands thoroughly and keep it out of reach. The toxicity of lily of the valley—especially for pets—is a serious issue that is all too often underestimated.
On May 1, 2026, alongside the lily-of-the-valley tradition, the manifestation intersyndicale dans Paris and the ample activities of the public holiday, there’s plenty to keep the day pleasantly busy. To learn more about the origines de la tradition du muguet le 1er mai, note that it all goes back to the 16th century and King Charles IX.
