French law prohibits the possession, planting, or cultivation of Sosnowsky's hogweed (Heracleum sosnowskyi), a perennial herbaceous plant originating from the Caucasus region. The ban stems from the plant’s dangerous nature and invasive characteristics. Individuals found in violation of this law could face up to three years in prison. The legislation has been in effect for several years, aiming to control the spread of this potentially harmful species. Authorities are concerned about the plant’s ability to cause skin reactions and other health issues. Gardeners are advised to familiarize themselves with prohibited plant species to avoid legal repercussions. The law underscores the seriousness with which France addresses the threat of invasive flora.
