Tall Verbena
Verbena bonariensis
flowerTall verbena is an airy, see-through perennial, grown as an annual in cold zones, whose wiry, branching 3 to 6 foot stems are topped with clusters of small purple flowers from summer to frost. Despite its height it is sparse enough to plant near the front of a border, and it is one of the very best butterfly plants.

🌱 Growing Guide
Start seed indoors about eight weeks before the last frost, surface-sowing for light, and transplant after frost into average, well-drained soil in full sun. Tall verbena tolerates poor, dry ground once established and dislikes wet feet. It self-sows freely, so it often returns even where winters kill it; leave a few seed heads if you want volunteers.
🌼 Have a different variety?Cultivars of the same species usually share the same basic care, and they differ mainly in flower color, height, and bloom form, not in how you grow them. So this guide still applies even if your exact variety isn't the one shown.

✅ Plant alongside
Good neighbors that attract beneficial insects or deter pests
- Black-Eyed Susan: A native pairing that extends the pollinator and butterfly buffet
- Salvia: Adds nectar for bees and hummingbirds on the same long season
- Zinnia: A fellow butterfly magnet that fills the lower tier below the airy stems
🛡️ Pest & disease prevention
Proactive ways to stop trouble before it starts. Tap a name with an arrow for its full guide
Verbena is seldom bothered; rinse off any clusters and support beneficials
Give it full sun and airflow and water at the base, not overhead
🌸 Blooms & cutting
Cut long stems for the vase as the flower clusters open; regular cutting and deadheading prolong the bloom. Leave the final flush standing to self-sow and to feed late butterflies and seed-eating birds.
🥗 Nutrition & benefits
A premier nectar plant: swallowtails, monarchs, and other butterflies, plus bees, hoverflies, and hummingbirds, work the long-blooming flowers, which support late-season migration.
