Buenos Aires Verbena (Verbena bonariensis) Brazilian Purple Bonariensis Patagonica Flower Seeds

Buenos Aires Verbena (Verbena bonariensis) is a garden favorite known for its airy clusters of small purple blooms atop tall, slender stems. This stunning Brazilian native, sometimes called Purpletop Vervain or Argentinian Verbena, provides long-lasting color and movement in the garden from mid-summer to frost.

The upright habit and light texture make Verbena bonariensis a gorgeous addition to cottage gardens, pollinator habitats, and modern prairie designs. Butterflies, bees, and hummingbirds frequently visit its rich nectar-filled flowers, making it a reliable pollinator magnet.

This non-GMO, easy-to-grow perennial (often treated as an annual in colder zones) thrives in full sun and well-draining soils. Its tall height and delicate appearance make it ideal for background planting or adding vertical interest throughout your borders and beds.
