Encyclopaedia of Rhododendron Hybrids

“In the Encyclopedia of Rhododendron Hybrids Peter and Kenneth Cox provide individual descriptions of over 1400 hybrids and a further 500 are included in the text. Each entry contains full details of parentage, hardiness, height, etc. and a critical appraisal of performance in different climates – and there are more than 200 colour photographs.” (Donated by the R.S.C. in memory of Barbara Hall.)
