The following is information on a new resource for perennial diseases. Landscapers and nurserymen should consider adding this reference to their libraries.
An excellent new reference for plant enthusiasts was just published by APS Press, “Diseases of Herbaceous Perennials”. It will be the 'bible' of perennial disease identification for some time. It is full of excellent full color photos of your favorite diseases comparable to other coffee table books. Horticultural information and pictures of healthy plants are provided by Dr. Alan Armitage, noted perennial plantsman. Ordering information can be found at
