Verbena rigida aka Veined Verbena

Verbena rigida, also known as slender vervain or tuberous vervain, is a flowering herbaceous perennial plant in the family Verbenaceae. Native to Brazil and Argentina, it is not fully hardy in temperate climates and is often grown from seed as an annual. This small, bushy, spreading plant grows up to 30cm tall and features oblong leaves and dense clusters of small, purple flowers that bloom from early summer to autumn. With a spreading habit and stalkless toothed leaves, Verbena rigida adds a vibrant touch to gardens with its bright purple or magenta, scented flowers held on branched stalks. It has gained recognition from the Royal Horticultural Society, receiving the Award of Garden Merit. This low-growing perennial species is a popular choice for sunny gravel gardens and wildlife gardens, as it not only produces an abundance of punchy purple flowers but also self-seeds, ensuring its presence year after year.
