The spiky panicles of blue vervain (Verbena hastata) bloom much of the summer atop 3- to 5-foot-tall stems. The flowers are typically purple, but these seeds may produce some pink-flowered plants as well. (I originally sowed seeds purchased as ‘Rosea’ but ended up with a mix of purple- and pink-flowered plants.) As you may guess from its other common name, swamp vervain, this species thrives in moist- to wet-soil sites and can be a good choice for a rain garden. It’s a magnet for bees, wasps, and other pollinators and is a host plant for the common buckeye butterfly. Self-sowing is possible. Native to much of North America. Full sun. Perennial; Zones 3 to 8.
Harvested in early September 2023. At least 30 seeds. Unknown ecotype. Shipping to US addresses only.
