That delicate white flower may be hiding a bigger problem.
With its white flowers and fern-like foliage, wild chervil may look harmless at first glance. In reality, this non-native plant can spread aggressively and compete with native vegetation. It has been found in various parts of the area, including Collingwood, Ontario, making identification important for property owners.

Wild chervil belongs to the parsley family and is typically found along roadsides, ditches, fields, and other disturbed areas. It can grow between one and four feet tall, although some plants can reach more than six feet. Its hollow, hairy stems and divided leaves can make it look similar to other members of the carrot family.
Common signs of wild chervil include:
- Fern-like leaves divided into many small leaflets
- Hollow stems with soft hairs, especially near the base
- Small white flowers arranged in umbrella-shaped clusters
- Shiny dark-brown seeds as they mature
- Dense growth along ditches or property edges
Wild chervil primarily spreads through seed. Once established, it can compete with native plants for light, water, and nutrients. Its large taproot also makes it challenging to control, and leaving portions of the plant behind can allow it to regrow.
At WillowStone, we do not believe in treating every unwanted plant the same way. Our invasive species control process begins with proper identification and an assessment of the surrounding landscape. From there, we can develop an approach suited to the property and the plants that need to be protected.
If you have noticed wild chervil spreading across your property, we are here to help. Get started with an assessment and we’ll develop a plan for effective management.
