Here's someone that just might be the gardening guru you are looking for: the badly behaved gardener Kim Stoddart. She sounds like someone who's philosophy of gardening is somewhat close to TPP's who is a bit of a bad-boy gardener himself, it's just that he really likes gardening and is thus perhaps a bit more engaged in the process. As for flaunting gardening rules, go for it. But as a botanist you start from a different perspective in that you know what and how plants do things, sometimes. At any rate, Kim is a breath of fresh air in gardening circles, but a book? No! You sit around with a cocktail!
