Growing Verbena: Climate, Planting, and Maintenance Tips

Overview

Verbena is a perennial flower often grown as an annual in cooler climates. Dozens of cultivars thrive across the U.S., producing small (1–2 inch) blooms in red, pink, purple, white, orange, and multicolored shades. Plants can spread 4–6 feet wide.

Climate Adaptation

Verbena returns yearly only in warmer zones (USDA 5–10 as an annual). It prefers drier, desert-like climates and can struggle in hot, humid conditions where summer heat may halt blooming.

Growing Conditions

Full sun (6+ hours daily) and well-draining soil are essential. Plants won't reach their potential in constantly moist or damp soil.

When to Plant

As an annual: plant in late spring or early summer. As a perennial: plant in spring after frost danger passes.

Planting Instructions

Dig a hole large enough for the root ball. Set the plant, firm soil around it, and water thoroughly. Pinch back branches after planting to encourage bushier growth. For seeds, start indoors 8–10 weeks before outdoor transplanting.

Maintenance

Water deeply for 1–2 weeks after planting to establish roots, then avoid overwatering (causes root rot). Fertilization isn't required, but a 16-4-8 fertilizer can be used if desired. In perennial zones, cut back at season's end and mulch before winter.
