For successful seedlings,
see the growing notes at the bottom of the page!

Blue vervain (Verbena hastata) is a native perennial plant, recognizable by its long square stems that can reach up to 1.5 metres in height, topped with upright spikes of small purple flowers arranged in crowns. These flowers are particularly attractive to pollinators, including bees, butterflies, and even hummingbirds. Adapted to wet environments, blue vervain naturally grows near lakes, streams, and marshy areas, making it an excellent choice for naturalizing shorelines and wetlands. In a garden, it prefers fresh, moist soil to thrive.

Medicinal and Culinary Uses
Blue vervain is used for its tannic, antispasmodic, calming, and fungicidal properties. In herbal medicine, it is considered a bitter tonic and is often used in tinctures due to its very bitter taste. In infusions, it is generally combined with other plants to soften its bitterness while benefiting from its soothing effects and benefits for the digestive system.

Ecological Roles
Blue vervain plays an important ecological role by attracting various pollinators throughout its flowering period. Its flowers provide nectar and pollen to bees, butterflies, and hummingbirds, thus supporting local biodiversity. In naturalization projects, it helps stabilize wet soils and enrich riparian zones while creating a welcoming habitat for insects and birds.

Blue vervain seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
