Perennials
Verbena bonariensis
Purpletop Vervain
Verbena bonariensis, commonly known as tall verbena or purpletop vervain, is a graceful perennial known for its airy structure and clusters of small, vibrant purple flowers. Blooming from mid-summer to early fall, it produces delicate, globe-shaped flower heads held aloft on tall, slender stems. The small, tubular flowers are highly attractive to pollinators, including bees and butterflies, and create a striking contrast against the plant's thin, wiry stems.

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
Where to see it
This plant can be seen in the perennial border at the Bellevue Botanical Garden.
