Overview

Beach verbena (Glandularia maritima, formerly Verbena maritima) is a rare Florida-endemic perennial groundcover with lavender-purple flowers and finely lobed green foliage. It adds long-season color to hot coastal and inland sites.

Mature Size and Habit

This low plant stays about 6–12 inches tall while creeping stems spread 3–5 feet and root at nodes, gradually forming a fine-textured mat.

Best Landscape Uses

Use it as ground cover, a sandy-slope stabilizer, coastal border, pollinator mass, container spiller, or dry-bed accent. Leave room for its stems to roam.

Sunlight

Plant in full sun for the fastest fill and heaviest bloom. Shade reduces flowering and produces a thinner mat.

Soil, Drainage, and Irrigation

Excellent drainage is essential. Beach verbena accepts acidic to alkaline sand, tolerates drought after rooting, and handles salt exposure. Water to establish, then irrigate sparingly.

Best Planting Season for Tampa and Central Florida

Fall through spring is ideal. It can be planted most of the year in Tampa with careful watering; space plants 3–5 feet apart for eventual cover.

Pruning and Maintenance

Trim wandering stems to define edges, remove dead growth, and tip-prune lightly for density. Avoid heavy fertilizer and frequent irrigation.

Wildlife Value

The long flowering season supports bees, butterflies, and other pollinators, especially in compact native and coastal gardens.

Cold and Heat Sensitivity

Best in zones 9A–11, it handles Tampa heat, sun, wind, and salt. A hard freeze may burn growth; prune damage after warm weather returns.

Safety, Roots, and Placement Warnings

There are no thorns, sharp leaves, woody roots, or widely reported major toxicity concern. Stems root as they travel, so keep them clear of drains and delicate neighbors. Never collect wild plants.

Invasive Concerns

This Florida native is not an introduced invasive, but UF/IFAS calls it an aggressive spreader in cultivation. Edge beds and remove rooted runners. Buy only nursery-propagated stock because wild populations are state endangered.
