Common Foxglove

Native:

Common Harebell (Campanula rotundifolia) also has purple flowers, but they are closer to a blue colour, and don’t grow in columns along the stem.

 

 

 

 

 

Native to Western Europe, the Mediterranean and Northwest Africa. Common Foxglove was brought to North America as both a garden ornamental and medicinal plant. It can now be found throughout most of Canada and is abundant in southwestern British Columbia.

Common Foxglove is abundant in disturbed areas, noticeably along roads, in fields, clearings, gravel pits and forest edges. It thrives in soils that are high in nutrients and moisture, as well as in medium heat and light.

Common Foxglove is a biennial or short-lived perennial that only produces flowers and seeds in its second year of growth. A single plant can produce up to 5000 seeds a year. Flowers need to be pollinated by bees in order to produce seeds.

Foxglove’s small and numerous seeds are dispersed by wind, water, contaminated soil and by gardening equipment. Common Foxglove is also sold in garden stores and nurseries as a garden ornamental, which aids in its spread.

Common Foxglove is currently found throughout the Sea to Sky Corridor, so Strategic Control is key.

DO:

• Regularly monitor properties for weed infestations.
• Ensure soil and gravel are uncontaminated before transport.
• Check wildflower mixes to ensure that they do not contain Common Foxglove.
• Ensure that plants are disposed of in a garbage bag if found in floral arrangements to prevent seeds from spreading.

DO NOT:

• Do not unload, park or store equipment or vehicles in infested areas; remove plant material from any equipment, vehicles, or clothing used in such areas and wash equipment and vehicles at designated cleaning sites before leaving infested areas.
• Do not plant Common Foxglove in a garden, no matter how well-contained its enclosure may seem.
• Do not move soil that has been contaminated with Common Foxglove.
• Do not compost Common Foxglove.

 

Control

Mechanical

Hand-pulling of Common Foxglove is proven to be the most effective and efficient method of control. If hand-pulling, the use of gloves is essential due to the plant’s toxic properties. Ensure that the entire root is removed and that all flowers are bagged. When removing flowers, make sure not to shake the plant, as seeds can be dispersed back into the soil.

Chemical

Trials on chemical control have been conducted and have concluded that metsulfron methyl and triclopyr showed some control on Common Foxglove, however, hand-pulling is considered to be the most effective method of control.

We recommend that any herbicide application is carried out by a person holding a valid BC Pesticide Applicator Certificate. Before selecting and applying herbicides, you must review and follow herbicide labels and application rates; municipal, regional, provincial and federal laws and regulations; species-specific treatment recommendations, and site-specific goals and objectives.

Biological

There is currently no biological control for Common Foxglove due to its toxic properties.
