Houseplants are all weird and wonderful, but there are some that outdo the rest for their ability to surprise us. Dr Chris Thorogood is a botanist at Oxford Botanic Garden with a clever sideline in painting plants: his new book, Weird Plants, is a brilliant book for anyone who wants to delve a bit deeper into some of the strangest corners of the botanical world.
