- Description
-
Blueweed is a weedy biennial plant native to Europe and Asia in the borage family. The plant has naturalized in parts of the USA, South America and New Zealand. It is found growing in dry pastures, roadsides, waste areas and coastal cliffs, sand dunes and the shingle. It is considered invasive in the state of Washington. It will grow up to 3 feet tall and have spikes of vivid blue flowers in May to September. This plant is poisonous to livestock and humans. The name vulgare means common in Latin.
Gardeners tend to either consider this a beautiful wildflower or a weed. If you desire to grow this plant, it is tolerant of poor soils in full sun and is drought and deer-resistant. Do not over-fertilize or plant in rich soils as this will decrease flowering. Be sure to deadhead spent blooms to prevent aggressive reseeding. Please see native alternatives listed to the left.
