Verbena bonariensis

Purpletop vervain   

Verbena bonariensis is a very useful addition to the herbaceous border or prairie garden. Its elegant appearance is characterized by slender, erect stems that reach heights of three to five feet. Atop these tall, wiry stems sit clusters of small, vibrant violet-purple flowers, which give the plant its distinctive common name, “purpletop vervain.” Verbena bonariensis is also a favorite among pollinators, drawn to its nectar-rich flowers, making it a valuable addition to any wildlife-friendly garden.
