The Geum Book
Sue has recently written a book on Geum which has been published by Plant Heritage. It contains chapters on:- the history and naming of geums, their use in medicine and cooking, hints on cultivation and propagation, pests and diseases, botany, and descriptions of all the cultivars, interspecific hybrids and species in the Collection. In nearly all cases each description is accompanied by a photograph, taken by Sue in her garden.
The book is currently out of print - sorry.
