Year-RoundThe sky-blue flowers bloom throughout the summer, adding color to any outdoor space. Its slender, lance-shaped leaves and overall graceful growth habit enhance its visual appeal. As a result, it can be used as a focal point in flowerbeds or as an attractive backdrop for other plants, creating a captivating display in gardens.
Blue Vervain has rough hairs and branching, and four-angled stems of the tall, leggy perennial wildflower known as blue vervains give them an exquisite look. They typically bloom each year from June to October. The first to bloom are those at the flower's base. The flowers open and ascend the stems with pointy tips and coarsely serrated edges. They resemble candelabras (chandeliers) because of all the flower spikes that form on top. They grow up to five feet tall.
It features a bushy growth habit and dense foliage, making it ideal for adding structure to your yard. Its bushy appearance makes yards look fuller. The lance-shaped leaves come from their stems in alternating patterns, creating a textural contrast with other plants. The tiny, brightly colored blossoms enhance the aesthetic and architectural appeal of gardens and landscaping.
Blue Vervain blooms boast a variety of colors, ranging from blue to deep purple to light lavender. On rare occasions, the flowers are white. The blooms have five joined petals at the base that create a small tube and are around 1/4 inch wide. A little stem supports the thin, lance-oblong leaves that grow up to seven inches long and one inch wide. These leaves have a pointy tip, coarsely serrated margins, and a broad base. The slightly hairy stems can be either green or reddish.
They have bright blue-purple flowers containing a lot of nectar and pollen, which attract butterflies and other pollinators, such as bees and hummingbirds. Both the Verbena moth and the Common Buckeye butterfly lay their eggs on blue vervains. These plants usually attract the most pollinators during late summer and fall. Because few other plants bloom simultaneously, they attract many late-flying pollinators, which is good for the environment because it increases biodiversity.

Care
Blue Vervain thrives in moist, well-drained soil and can tolerate occasional flooding. It benefits from regular watering but should avoid overwatering. Prune dead or damaged stems in early spring to encourage new growth and maintain their shape.
Plant Reproduction
Blue Vervain spreads slowly through rhizomes and by self-seeding.
Planting bare-root perennials is best in any season if they are dormant; we only sell dormant plants. Planting them year-round is also excellent if you can get dormant perennials. When your bare-root perennials arrive, soak the roots in water for a few hours to rehydrate them. Lant by digging a hole wide enough to spread the roots comfortably and deep enough to place the top portion crown (where the roots meet the stem) at or slightly above ground level. Position the plant in the hole, backfill with native soil, and gently firm the soil around the roots—water well after planting to settle the soil around the plant and eliminate air. Apply a 2-3 inch layer of mulch to keep weeds at bay and moisture locked in, keeping the mulch away from the crown. Irrigate plants regularly during the first few weeks of drought; never water in full sun, and water late in the evenings to ensure the roots are established well. Fertilize sparingly in the first year, using a balanced, slow-release fertilizer in subsequent years as needed.
