The Perennial Plant Association is in the process of developing a Perennial Trialing Program. The idea is to develop an evaluation program for perennials in various climatic zones in North America. The evaluation of perennials in diverse growing areas will benefit breeders, growers, retailers, and ultimately the home gardener. There has been a tremendous influx of new cultivars, many which have not been fully evaluated in all areas of North America.

The objective is to develop a program that will add credibility to new cultivars. Evaluation sites will be placed throughout North America with an evaluator for each site. Initially the program will start with genus wide comparisons of currently available and soon to be released cultivars. The goal of the Perennial Trialing Committee is to start the program in fall 2010.
