Plant Profile: Verbena stricta

Hoary Vervain, a wildflower native to North America and part of the verbena family, is relatively uncommon along the North Carolina coast but thrives abundantly in the central regions of the United States. This resilient plant can be found in various habitats, including prairies, thickets, and fields, and it exhibits drought resistance, favoring medium to dry sandy, rocky, or clay soils with excellent drainage.

As a clump-forming species, Hoary Vervain propagates naturally through self-seeding. To manage its spread, consider deadheading the flowers. When grown from seed, it typically begins to bloom in its second year, producing spikes of blue-purple flowers (with pink variations being rare) that attract butterflies and bees. The plant's common names stem from the fine hairs present on its leaves, stems, and flowers.

For optimal growth, plant Hoary Vervain in full sunlight and ensure the soil is well-drained, avoiding excessive watering. It is well-suited for dry, sunny areas, making it an excellent choice for rock gardens or naturalized settings like prairies and meadows.
