Ellen Ann Willmott was a remarkable woman whose achievements in horticulture, botany, landscape architecture, photography and more, should have made her one of the most well-known trailblazers of her age. Yet, both posthumously and within her lifetime, she instead became known as a bitter, cantankerous and eccentric miser, and her reputation has been forever stained by the image of her maliciously seeding other people's gardens with thorns.

The beginnings of this prickly myth can be traced back to her conspicuous absence at what should have been the pinnacle of her career: the Royal Horticultural Society's inaugural Victoria Medal of Honour Award ceremony, at which she was due to be one of only two female recipients. Universally interpreted as the rudest of snubs, nobody has ever stopped to question why Ellen wasn't there, or if she was really as difficult and mean as she has been portrayed ever since.
