100 Verbena Hastata Seeds – Blue Vervain Native Wildflower – Tall Purple Pollinator Perennial for Rain Garden
Verbena hastata, commonly known as blue vervain or swamp verbena, is a native North American wildflower prized for its tall, branching spikes of small purple-blue flowers. This clump-forming perennial blooms from mid-summer into early fall, adding vertical interest and vibrant color to meadows, rain gardens, and pollinator plantings. Its nectar-rich blooms attract bees, butterflies, and other beneficial insects, while the seeds that follow provide food for birds.
Blue vervain is well-suited to moist soils and is an excellent choice for rain gardens, bioswales, and naturalized areas. It also performs well in perennial borders and cottage gardens when given consistent moisture. Its tolerance for wet conditions makes it a reliable option for challenging sites.

Planting & Care
Sow seeds indoors 6-8 weeks before the last frost or directly in the garden after the danger of frost has passed. Lightly press seeds into the soil surface; do not cover deeply, as light aids germination. Keep the soil consistently moist until germination, which typically occurs in 14-30 days at 65-75°F. Once seedlings have several sets of true leaves, transplant them outdoors after hardening off.
Blue vervain thrives in moist to wet soils and benefits from regular watering, especially during dry spells. Deadhead spent flowers to encourage continued blooming, or leave seed heads for birds. In late fall, cut back stems to ground level. This low-maintenance perennial returns each year in suitable climates.
