Quick facts

About Slender vervain

Verbena rigida, also known as Rigid Verbena or Buenos Aires Verbena, is a long-flowering perennial plant admired for its vibrant spikes of purple blooms. Its upright stems and rough foliage make it a resilient and attractive choice for borders, edgings, or as groundcover, bringing a wild and colorful touch to the garden. It is particularly effective in low-maintenance or xeriscaping gardens.

Native range

South America, particularly Brazil, Argentina, and Uruguay.

Care tips

This verbena thrives in full sun, requiring at least 6 hours daily for optimal flowering. It tolerates drought well once established, but regular watering during intense dry periods will enhance its bloom; avoid waterlogging. It prefers well-drained soils, even poor ones, and does not require much fertilization. A common mistake is planting it in dense shade, which results in sparse flowering and leggy stems.
