With many choices of vendors out there for peony, I have always found it extremely worthwhile to buy from the grower. They offer both knowledge and quality that I have not found elsewhere. Having talked with many hybridizers over the years, it is their unmistakable passion for what they do and quality of their product that has me returning to them year after year.
