In the last 20 years or so Verbena bonariensis has become a deserved ‘best seller’ perennial flowering from mid-summer to the first frosts. Often when a plant becomes fashionable, and is seen ‘everywhere’ it can become diminished by familiarity, and yet the many good qualities that make this plant so popular are self-evident. Beth Chatto and Christopher Lloyd were both extolling its virtues in their writings of the late 1970s and early 1980s.
