Any book by Christopher Lloyd is beyond price. He was born with a trowel in his hand and in over 80 years of life never stopped learning about plants and gardening. His own garden at Great Dixter was his research lab and he was constantly trying out new plants, plant combinations and gardening techniques. He was a plantsman first and foremost, rather than a garden designer - but then he didn't need to design the structure of the garden at Dixter, that had been done by the great architect Lutyens in consultation with Christopher Lloyd's father.
Yes, a great gardener. But even more than that he was a prolific and talented writer with a consummate command of English. There may have been greater gardeners in the 20th century (though not many) and there were greater writers, but no-one combined the two skills to such effect as Christopher Lloyd did. Buy this book and any other by him and you will learn and be entertained in equal measure.
The star rating on this site only goes up to five. I would give any book by Christopher Lloyd at least ten.
