Vervain (Verbena lasiostachys) is a perennial herb in the Verbena family that grows in northern, central, and southern California, as well as Oregon. It is found primarily along the coast, in the Coast Ranges, foothills, and scattered inland locations. This aggressive spreader is a pioneer species that thrives in wet places, at elevations ranging from sea level to 8,200 feet.
Vervain has a long blooming season, with small pink to purple flowers densely clustered on spikes rising above its nettle-like leaves. It goes completely dormant in winter and grows quickly in early spring. Given its spreading nature, it should be used in areas where it can be controlled.
This plant is an excellent choice for butterfly gardens, attracting pollinators with its nectar-rich flowers. The flowers will also draw hummingbirds, making it a great addition to gardens looking to support a variety of wildlife.
