Common Bugloss (Anchusa officinalis L.)

LRISS Category: Eradicate

Biennial or perennial forb with purple-blue flowers with white centers. The flower buds are coiled on their stem and straighten as the flower open. The leaves are stalked and lance shaped. They have a leathery feel and the leaves and stems are covered in stiff hairs. Blueweed grows up to 80cm tall. It spreads primarily by seeds.

Impacts

Blueweed spoils hay because the succulent leaves and stems cause mold. It can invade rangelands and pastures. It has the capacity to reduce yield in hay lands.

Management

Removal of small infestations in the first year before flowering can be successful. Removing before it sets seed is important.
