Narrow-Leaved Vervain (Verbena simplex) is a beautiful wildflower that is becoming increasingly rare in the wild. Charming lavender flowers begin emerging at the bottom of the raceme in June. New flowers will progressively emerge above the older ones, which gives this wonderful plant a long bloom period.
Verbena simplex is also comparatively drought tolerant. It can be used as a border plant in a combination with other non-competitive perennials or can be planted in rock gardens or sandy areas. V. simplex nectar attracts various bees and moths (carpenter bees, cuckoo bees, leaf-cutting bees, green metallic bees and verbena moth). It is also a host for Common Buckeye butterfly larvae.
