Verbena, Bonariensis

Verbena bonariensis (Tall Verbena) Verbena bonariensis, also known as tall verbena, purple top vervain, or Brazilian verbena, is a tall and slender-stemmed perennial plant that displays rich lilac flowers in tight clusters atop long stems. Here are some key characteristics of Verbena bonariensis: Appearance: Clusters of small purple flowers float on long, airy stems, tempting passing butterflies to stop for a sip. The plant produces 23" clusters of pinkish purple blooms on wiry, self-supporting stems. The dark green leaves are very narrow and sparse, giving the plants a remarkably light and airy appearance. The flowers rise well above rosettes of lance-shaped, dark green leaves that hug the ground, creating a striking visual display. The plant is known for its tall and airy growth, with bright lavender clusters held high on stems that wave in the breeze from mid-summer to frost . Growth and Care: Verbena bonariensis is a hardy perennial in zones 7 to 11 and is grown as an annual in cooler climates. It is best grown in evenly moist, well-drained soils in full sun and tolerates poor soils as long as drainage is good. The plant is a superior nectar plant, attracting hummingbirds, butterflies, and other pollinators. It is a low-maintenance plant that is easy to grow and thrives in full sun with well-drained soil . Use in Gardens: This plant is a first-rate cut flower and can be put at the front of the border without blocking the plants behind. It can be planted in groups to create a lilac haze or scattered here and there to provide color through the dog days. Even mature gardens can accommodate this upright, narrow annual, which reseeds itself to create pleasant surprises the following year. It is also known for its compact stature, with dense clusters of small, lavender to violet flowers over a long season, making it a favorite among diverse pollinators, including migrating Monarchs .
