New Trees: Recent Introductions to Cultivation details 850 species of tree introduced to cultivation in the past 40 years and documents our changing treescapes in the face of global warming. The 992-page doorstop complements the iconic tree text Trees and Shrubs Hardy in the British Isles by WJ Bean, first published in 1914 and revised until the 1970s.
As well as botanical details. the book looks at the horticultural needs of each species and contains a section on modern tree-growing techniques. The author, gardener and botanist John Grimshaw, said: "A wealth of new trees are now thriving in the UK thanks to our changing climate."
Kew arboretum head Tony Kirkham said in a foreword that the number of species missing from the original masterpiece by WJ Bean had increased over the years. "Recently I needed more information on Acer pictum subsp. okamotoanum, a tree I collected in South Korea in 1989, but found it missing from Bean's work."
The £99 book, which took five years to complete, includes technical descriptions from plant curator Ross Bayton and line drawings by Zimbabwean Hazel Wilks.
Royal Botanic Gardens, Kew, and the International Dendrology Society worked together on New Trees: Recent Introductions to Cultivation.
