Wonderful Colour Purpletop Vervain Flower
Purpletop vervain, also known as tall verbena or Brazilian vervain, is a herbaceous perennial plant native to South America, particularly Brazil and Argentina. It is widely cultivated for its airy, graceful form and clusters of small, lavender-purple flowers that attract pollinators like bees and butterflies. Here's a detailed overview of this plant, including its appearance, habitat, and benefits:
Appearance and Growth
Purpletop vervain is known for its slender, upright stems that can grow between 3 to 6 feet tall. The plant forms clumps, and its stems are rigid, often square in cross-section. The leaves are long, narrow, and rough-textured, with serrated edges, growing in a basal rosette. While the leaves are not the main feature of this plant, the real attraction lies in the flowers.
The flowers of purpletop vervain are tiny but numerous, growing in clusters atop the tall stems. They are typically a vibrant lavender or purple color, forming a delicate contrast with the thin, wiry stems. The flowers bloom from mid-summer through fall, providing a long-lasting display of color. The plant has an ethereal quality, with its tall, sparse stems swaying in the breeze, often giving a naturalistic feel to gardens.
Habitat and Growing Conditions
Native to subtropical regions, purpletop vervain prefers full sun and well-drained soil. It is hardy in USDA zones 7-11, but can also be grown as an annual in cooler climates where it may not survive winter. The plant is tolerant of heat, drought, and even poor soils, making it adaptable to a variety of conditions, although it thrives best in rich, loamy soil. Despite being a non-native species in many regions, it has not generally been considered invasive due to its modest growth rate and specific habitat requirements.
In its native South America, purpletop vervain often grows in grasslands and along roadsides. It has been introduced to various regions, including North America, Europe, and parts of Africa and Asia, where it is used in ornamental gardens.
