About Purple vervain
Verbena litoralis, commonly known as Seashore Vervain, is an upright and branching perennial herbaceous plant that can reach up to 1.5 meters in height. It is characterized by its spikes of small purple or bluish flowers that bloom profusely during summer and autumn, attracting pollinators. It is ideal for low-maintenance gardens, rockeries, or as part of naturalized borders, adding a wild touch and lasting color.
Native range
Tropical and subtropical Americas, from the southern United States to Argentina and Chile
Care tips
It requires full sun exposure for optimal flowering, tolerating some partial shade in very hot climates. This plant is drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out between waterings to prevent waterlogging. It prefers well-drained soils, even poor or sandy ones, and is not demanding in terms of nutrients. A common mistake is overwatering, which can lead to root rot; it's better to underwater than overwater.
