Blue Vervain

The Blue Vervain (verbena hastata) plants share their beautiful blue flowers over a long season! An excellent choice for border planting, these plants are loved by pollinators like bees! The mature Blue Vervain plant will grow between 2-4’ tall and spread 1-2’.

However, some have been known to grow up to 6’. The flowers form spearlike buds up to 6” long, each composed of many small ¼’ blossoms that flower from bottom to top over the summer. One can pinch the stem near the top to encourage and improve flower formation to increase branching. Native to many of the marshes of North America, the leaves and flowers were used medicinally by some tribes.

While these flowering plants will bloom throughout the summer, they are perennial in the right conditions. In ideal conditions, this variety of vervain will propagate from seeds but can also reproduce from the roots below ground. It spreads from the roots and often leads to clumping in the wild, where many plants grow into thick bunches.

While an excellent choice for borders because of its height, imagine how you can use this plant to form crisp lines and accents or soften an edge for a wild prairie look.

Distributed across North America, the Blue Vervain is tolerant of conditions across the continent with USDA Zone Hardiness of 3 to 8. Particularly suited to wetter environments and tolerant of a variety of soil types, once established, these plants have a perennial habit and can re-seed, volunteering themselves outside the garden. American Blue Vervain is a fantastic choice for wild pollinators too!
