As gardeners and propagators in an increasingly connected world, many of us take plants far beyond their natural ranges. This is sometimes result in plants becoming naturalised in a foreign climate, and eventually becoming invasive. This book provides a counter-argument to the classical debates around invasive, and our obsession with returning natural spaces to their "pristine" state. It challenged my views as a gardener, as a student of ecology, and as a person who finds solace and comfort in familiar and native vegetation. I highly recommend this book - in which Marris puts across lucid and powerful arguments sufficient to create a different world-view. Already read it? Let me know what you thought below!
