The story

Blue vervain lifts candelabra spikes of small purple flowers over wet meadows across North America, opening a ring at a time from the bottom up. It has a long history as a traditional herb among many Native nations.

Planting

Full sun and moist to wet soil. Sow in fall; the seed needs a cold winter.

Growing

Let it self-sow; plants live only a few years.

Harvest and use

Nectar for small native bees and skippers, food for buckeye caterpillars, and seed for sparrows and juncos.

What to watch for

Powdery mildew in dry soil. It reseeds freely.
