Santos Purple Stiff Verbena

Santos Purple Stiff Verbena (Verbena rigida 'Santos Purple')

Santos Purple Stiff Verbena is a sun-loving groundcover perennial that lays down intense purple color for months with very little fuss. It spreads to knit open spaces together, making borders look fuller and more finished without constant replanting. The dense flower clusters draw pollinators and keep the garden active through summer and into fall. Once established, it handles heat and short dry spells well, especially in well-drained soil.

Distinctive Features

This cultivar forms a low, spreading mound of rough-textured, deep green leaves topped with short spikes of vivid purple flowers. Bloom is long and often repeats from late spring through summer and into fall, creating a carpet-like effect when planted in groups. The stems are sturdy and the plant stays low, so it works as a clean edging plant without flopping. In warm climates it can spread widely over time, which is an advantage for coverage and a reason to give it room in tighter beds.

Growing Conditions

• Sun: Full sun for the strongest flowering and the tightest, most durable growth.
• Soil: Well-drained soil is essential, and sandy or rocky soils are ideal.
• Water: Low to moderate water, drought tolerant once established, with occasional deep watering improving bloom in heat.
• USDA Zones: Zones 7a to 11.
• Mature Size: About 10 to 12 inches tall and about 3 to 4 feet wide as it matures.

Ideal Uses

• Focal Point: Mass it in a sunny bed where the saturated purple bloom reads as a bold, ground-level centerpiece for the season.
• Groundcover: Use to cover open soil quickly and keep planting beds looking finished and weed-resistant.
• Border Edging: Line paths and bed fronts for a low ribbon of color that stays neat and intentional.
• Rock Gardens: Plant in gritty sites where drainage is fast and summer heat is reflected.
• Slopes: Use on sunny slopes to knit soil together with spreading growth and long bloom.
• Containers: Plant in large pots or troughs for a long season of color with minimal maintenance.

Low Maintenance Care

• Trimming: Shear lightly after a heavy bloom flush to refresh growth and encourage another round of flowers.
• Watering: Water deeply during extended drought, especially in the first season and in containers.
• Drainage: Avoid wet soils and improve drainage in heavier ground to prevent decline.
• Cleanup: Remove spent stems for a tidier look if desired, especially in more formal plantings.
• Winter Care: Cut back in late winter or early spring as new growth begins.
