I’ve been meaning to read ‘Bringing Nature Home’ by Douglas Tallamy for a while. American readers will probably heard of it – the book which makes the case for growing native plants to support biodiversity, and something of a bible for ‘nativists’. Who, I gather are gaining strength in the US. Whenever I visit I hear complaints from gardeners about “native nazis” – people who dogmatically assert that anyone growing non-natives is somehow an enemy of the environment. It seems a tragedy that an important debate has gotten so bad-tempered.
