Comment:

Blue vervain spreads through rhizomes. It can grow in disturbed sites and is commonly found in moist meadows, thickets, pastures, riversides, marshes, ditches, and river-bottom prairies.

Wildlife Value:  Cardinals, sparrows, and juncos eat the seeds. Cottontail rabbits eat the foliage, however most mammals avoid its bitter taste. Larval host plant for verbena moth and the common buckeye butterfly. Long and short tongued bees collect the nectar and sometimes the pollen. Other bee pollinators include: epoline cuckoo bees, eucerine miner bees, halictid bees, and the verbena bee (a specialist pollinator). In addition the thread-waisted wasp, bee flies, thick-headed flies and golden soldier beetle are also known to all visit blue vervain.
