This native perennial is easily recognized by its unique branching flower spikes that resemble a multi-armed candelabra. Tiny, vibrant violet-blue flowers bloom in succession from the bottom up in the July heat. Unlike many garden perennials that shy away from "wet feet," Verbena hastata thrives in moist-to-wet soils, making it an invaluable choice for rain gardens, pond edges, or that low-lying corner of the yard where other plants struggle.

Vertical Interest: Its tall, slender habit adds height without adding bulk, allowing it to weave beautifully between other plants.
Naturalizes Easily: A biennial plant that is a wonderful self-seeder. It also will slowly spread through rhizomes allowing it to fill in gaps over time, but it will not compete well with more aggressive vegetation.
Color: The violet-blue flower spikes can bloom for up to 2 months.
Butterfly Magnet: A vital nectar source for a wide array of butterflies, including Swallowtails, Fritillaries, and Skippers.
Native Bee Support: Blue vervain attracts a variety of different native bees.
Songbird Food: In the fall, the slender spikes produce tiny seeds that are a favorite for finches, and sparrows.
Pro Tip: Because Blue Vervain grows quite tall and narrow, plant it in clusters of three or more. This creates a stunning "haze" of purple-blue color that is much more impactful than a single specimen, and it provides extra support for the stems in windy areas.
An elegant, long-lived native that looks more like a small shrub than a typical flower. In late spring, it produces tall spikes of deep indigo-blue flowers that resemble Lupine, providing a cool contrast to the yellow-heavy palette of the summer garden. It is often called the "Perennial of the Year" for good reason—it is practically indestructible and offers a shrub-like presence without the woody maintenance.
Sun Exposure Full Sun to Partial Shade (Best in Full Sun)
Water Needs Low to Medium; exceptionally drought-tolerant once established
Soil Type Adaptable; thrives in Clay, Loam, Sand, or Rocky soil
Mature Height 3 – 4 feet
Deer Resistance High
Bloom Time May – July
Bloom Color Blue
Plant Spacing 2 – 3 feet
Deep-Rooted Longevity: It features one of the deepest taproots of any native plant, making it nearly impossible to kill once established—but also very difficult to move! Pick its "forever home" carefully.
It will spend most of the first couple years developing mostly below ground
Shrub-like Structure: While it dies back to the ground in winter, it regrows into a dense, mounded shape with beautiful blue-green, clover-like foliage that stays attractive all summer long.
Because of it’s wide form, generous spacing is recommended.
Bees: The "pea-shaped" flowers are specifically designed for heavy-bodied bees, like Bumblebees, who are strong enough to push the petals open to reach the nectar.
Butterfly Host: It serves as a vital nursery for several butterfly species, including the Wild Indigo Duskywing and the Frosted Elfin.
