Rough chervil is a plant primarily native to Eurasia, spanning regions from the Mediterranean Basin to temperate zones in the north and east. It is also natively established in North Africa. Beyond its historical range, rough chervil has been introduced to parts of Northern Europe and even as far as New Zealand, though it is not considered globally cultivated.

Rough chervil is a plant native to Europe and parts of Asia. It is considered a weed due to its invasive characteristics, such as a rapid growth rate, ability to produce a large number of seeds, and overall robustness. One aspect that makes this plant particularly harmful to gardens is its vigorous underground root system that can quickly colonize an area, outcompeting native plants for nutrients and sunlight. Additionally, rough chervil contains toxic compounds which can be harmful if ingested by humans or animals. The weed spreads mainly through seed dispersal, which can happen via wind, water, or unintentionally by humans and animals moving through an area. Its seeds are hardy and can lie dormant in the soil for many years, allowing this plant to re-establish itself even after efforts to remove it.

The best season for removal of rough chervil is late spring or early summer. It's crucial to remove the plant before it seeds to prevent further spreading. Here are a few methods:
