Verbena bonariensis - A Tall and Airy Perennial
Verbena bonariensis, commonly known as Purpletop Vervain, is a tall and airy perennial that adds a touch of elegance and colour to the garden with its clusters of small, lavender-purple flowers. Perfect for borders, cottage gardens, and wildlife gardens, Verbena bonariensis brings both beauty and a sense of lightness to various garden settings.
The standout feature of Verbena bonariensis is its tall, slender stems topped with clusters of small, lavender-purple flowers. These blooms create a stunning display from summer to autumn, attracting pollinators such as bees, butterflies, and hummingbirds. The flowers rise above the dark green, lance-shaped foliage, adding height and a delicate, airy quality to the garden. The upright, open growth habit makes Verbena bonariensis an excellent choice for adding vertical interest and a see-through effect in garden beds and borders.
Caring for Verbena bonariensis is straightforward, making it suitable for gardeners of all experience levels. Plant Purpletop Vervain in well-drained, moderately fertile soil and ensure it receives plenty of sunlight, as it thrives best in full sun.

In regions with harsh winters, a light mulch can help protect the plant, or consider growing it as an annual. With its low maintenance needs and beautiful, airy flowers, Verbena bonariensis is a wonderful addition to any garden, providing long-lasting colour and attracting beneficial pollinators.
