About plant names...

White vervain is native to North America.

Identification: Plants are 1-3′ (40-101 cm) tall, with a main stem that is hairy, hollow, and roughly square in cross-section. Leaves are opposite and unlobed, deeply veined, with irregular teeth. They are up to 6″ (15 cm) × 2″ (5 cm), varying from lance-shaped (lanceolate) to oval (ovate), on stems (petioles) up to 2″ (5 cm) long. The flowering spikes are the most unique feature of these plants: multiply branched, up to 10″ (25 cm) long and very narrow, disorderly looking, with tiny white flowers less than ⅛″ (3.2 mm) around. Only a few flowers appear at a time, and they are small enough so that the spikes are mostly green.
