Vervain (Verbena rigida) - Description
Verbena rigida (slender vervain, tuberous vervain), syn. V. venosa, is a flowering herbaceous perennial plant in the family Verbenaceae. It is native to Brazil and Argentina, and is not fully hardy in temperate climates, where consequently it is grown from seed as an annual. Growing to 60 centimetres (24 in), it has a spreading habit, with stalkless toothed leaves and bright purple or magenta, scented flowers in summer. Numerous cultivars have been selected for garden use. The species has gained the Royal Horticultural Society's Award of Garden Merit.
