Argentinian Vervain Overview
Verbena bonariensis is a tall airy perennial from the Verbenaceae family. It is a very popular garden plant, providing great architectural height at the back of a border or an attractive see-through screen along pathways. This species originates from South America. It is also known by the names Argentinian Vervain, Tall Verbena and Purple Top, amongst others. It produces an abundance of small purple flowers, arranged on thin, branched stems in structures known as umbels. These are clusters which radiate from a central stem point, producing flowers on stalks of roughly equal length, to form a flattened or slightly rounded, horizontal surface of blooms. This plant typically grows to 2m in height; it has an open form and few leaves, grown for the flowers over the foliage. It has been awarded a Royal Horticultural Society (RHS) Award of Garden Merit for its long flowering period. It is also part of the RHS “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. An excellent choice for encouraging pollinating insect wildlife into your garden!
