Identification and Reproduction

Identification 

• Biennial, short-lived perennial that is in the carrot/parsley family.
• Grows upright and can almost reach two metres tall

• Wild chervil has white flowers in umbrella-like clusters, with bract-like leaves under flowers. Clusters are found at the top of stem. Blooms occur from April to May. 

• Leaves are triangular, finely divided, resembling ferns, softly hairy. 

• Stems are ribbed, green, and has distinct hairs on lower portion 
• Tuberous roots can extend almost two metres into soil.
  

Reproduction: 

• Spreads rapidly through seed and vegetative fragments such as root buds.
• Seeds are easily dispersed by wind, animals and people. 
• Its deep taproot makes it difficult to remove. 

Look-alikes

Wild chervil has many look-alikes! We have a guide that helps you differentiate this plant from other look-alike invaive and native plants - See the guide here

Habitat & Ecology

• Wild chervil prefers moist, rich soils that are moderately disturbed.
• It is only found in open habitats. 
• It is commonly found along ditches, roadsides, fences, streambanks and moist woodlands. 
• Wild chervil is deemed regionally noxious in BC.

Impacts

Social: 

• Will crowd out forage plants.
• Can spread disease to crop species in the same family like carrot, parsnips, and celery.

Ecological: 

• Displace native plants and reduce biodiversity.
• Can reduce wildlife habitat.
• It uptakes nutrients and water resources aggressively, out-competing natives vegetation. 

Management

• Chemical control may not be an option as wild chervil is often found in wet sites near waterbodies. Chemical applications also may not be effective on the deep taproot. 
• Be cautious when purchasing wildflower seed mixes, especially if they are not locally produced. These can contain seeds of wild chervil and other invasive species.

Mechanical/Manual Control:

• Can be mechanically controlled if taproot can be entirely removed, this can be done through hand-pulling or digging. 
• Mowing can be effective prior to seed set. 
• Bag and seal any removed parts for landfill.

King County is also a good resource for historic and identification information, as well as a management guide.

The Government of Ontario is another good resource for explaining the history, identification, impacts, and spread of wild chervil.
