White Vervain (Verbena urticifolia)

''Verbena urticifolia'', known as nettle-leaved vervain or white vervain, is a herbaceous plant in the vervain family . It belongs to the "true" vervains of genus ''Verbena''.

White vervain has opposite, simple leaves on thin, rigid, green stems. The leaves look similar to those of ''Urtica'', which is the reason for the plant being named ''urticifolia''. The small flowers are borne in spikes; they open in summer and unusually for this normally bluish-flowered genus are white.
