An upright perennial with tall, branching stems reaching high, topped with tight, flat flower clusters. The Verbena bonariensis, or Argentinian Vervain, is a columnar perennial up to 2m with sparse, oblong mid-green leaves nearer to the base of the high rising stems which split to carry terminal clusters of small purple-pink flowers from mid-Summer.
