Île‑de‑France plant fairs and garden markets

If you were picturing a nonstop week of plant fairs all across Île-de-France from Monday, May 11 to Sunday, May 17, the reality is narrower. There are plant events in the region during that stretch, but the publicly listed calendar looks patchy, not packed. Basically, this is a week for targeted outings — one village fair here, one local swap there — rather than a giant regional gardening moment. ### So what is actually on this week? The clearest events inside the May 11–17 window are the Fête des plantes at Cugny, La Genevraye in Seine-et-Marne on Thursday, May 14, and a smaller plant-focused gathering at Parc des Glycines in Méry-sur-Marne on Sunday, May 17. Jardinez and Labouture both place those dates squarely in the week you asked about. ### Why does Cugny stand out? Cugny is the bigger, more classic plant-fair format. Its 19th edition is described as bringing together around 60 exhibitors tied to plants and gardens, plus an exchange corner, a raffle, and food areas. (sortiraparis.com) That sounds less like a simple sale table and more like the kind of half-day-or-longer outing gardeners actually plan around. ### What about Méry-sur-Marne? Méry-sur-Marne looks much smaller and more local. The listing says MéryAnimation is holding a fête des plantes at Parc des Glycines on May 17 from 14:00 to 17:00, with people invited to swap, buy, or sell plants, seeds, magazines, and small tools. (jardinez.com) So this one reads more like a neighborhood plant exchange than a full commercial fair. ### Are there other garden events nearby? Yes, but this is where the timing matters. (jardinez.com) Soisy-sur-Seine’s 16th Fête des Jardins ran on May 9–10, just before the week in question, and Neauphle-le-Château’s plant and local-products fair is listed for Sunday, May 10 — also just before the May 11–17 span. Those are real events, but they do not support the idea of a full week of fairs after Monday starts. ### Why does the “this week” roundup feel broader? (jardinez.com) Because the weekly Paris picks page is mixing categories. It flags “several plant festivals” as part of the week’s attractions, but it is a broad lifestyle roundup that also includes bread festivals, Brittany celebrations, parties, exhibitions, and family outings. In other words, plant events are one strand in a much wider events guide, not the sole focus. ### Is this more for shoppers or families? A bit of both, but the formats differ. Cugny looks built for browsing stalls, meeting growers, and making a proper outing of it. Méry-sur-Marne is more practical and community-driven — bring plants, trade seeds, maybe pick up tools, then head home. The catch is that opening hours and scale vary a lot, so you cannot treat these as interchangeable. ### What changed from the preliminary picture? The big change is specificity. (sortiraparis.com) Once you pin down actual dates and named events, the week stops looking like a dense regionwide circuit and starts looking like a short list of scattered local rendezvous, with the most substantial one landing on May 14 in Cugny. ### Bottom line? There are real plant outings in Île-de-France between May 11 and May 17, 2026 — but not a nonstop run of major fairs. If you want the most substantial stop, Cugny is the one to watch. (jardinez.com) If you want a quick, local, community-style swap, Méry-sur-Marne is the better fit.
