Vipers Bugloss (Echium vulgare)

Vipers Bugloss flowers.

It was introduced from Europe, and it grows best in sunny areas, such as meadows, overgrazed pastures, poorly drained slopes and roadsides. It usually will not do well in cultivated ground.

The flowers are bright blue with hot pink stamens and bloom June to September. Blueweed spreads from seed. Most of the seeds fall to the ground near the parent plant, but the rough seeds can stick to clothing, animal fur, and feathers and be carried to a new site.

NON-CHEMICAL CONTROL:

• Early detection is the best prevention. Destroy plants before they become invasive. Cut, bag and destroy flower heads when they appear.
• Digging or mowing plants throughout the growing season is very effective.
• Fertilize! Noxious weeds do not like fertile soil but grasses do. When grasses thrive, weeds don’t.
• No Bio-controls are being used in our area at this time.

CHEMICAL CONTROL:

• Several chemicals will work to control blueweed. Treatment works best in spring when the plant is young. Check with your local Noxious Weed Control Office for more detailed information.
