- Description
-
Hoary Vervain is a North American native wildflower in the verbena family and is sparsely found on the coast of NC but is abundant in the central part of the USA. It is found in prairies, thickets, fields and is drought tolerant, preferring medium to dry sandy, rocky or clay soils with good drainage.
Hoary Vervain is a clump-forming plant that naturalizes by self-seeding so deadhead to control spread if desired. When started from seed, it blooms in the second year, attracting butterflies and bees to its spikes of blue-purple (rarely pink) flowers. The leaves, stems and flowers have hairs giving it its common names.
Plant in full sun in well-drained soils and don't overwater. Use in a dry sunny location, in a rock garden or naturalized settings as prairies or meadows.
