Verbena 'Romance Pink'

Verbena, known in English as "vervain" and in French as verveine, is a genus of about 250 herbaceous and semi-woody flowering plants mostly native to the Americas, though there are some European species. Verbena hybrids, like this one, are widely available annuals bearing flat-topped clusters of small flowers in a wide variety of colours: pink, purple, red, white, peach, and bicolours. They are said to attract butterflies, though I haven't witnessed this myself.
