The plant's stem and leaves are fleshy and its white flower has five petals.
Verbena officinalis "V. officinalis" as a subspecies or variety. But despite the outward similarity, biogeography alone strongly suggests there is really no justification to include this North American native here, and DNA sequence data agrees. Instead, "V. halei" seems to be closely related to "V. macdougalii", perhaps with some interbreeding with the "V. menthifolia" lineage which might explain its Common Vervain-like traits. Common vervain has been held in high esteem since classical antiquity; it has long been associated with divine and other supernatural forces, and it has an equally long-standing use as a medicinal plant.
