During his 35 years with the PPA, Dr. Still has guided the Association to represent an evolving perennial industry.

Within a year and with great momentum, the PPA was incorporated. It is through Dr. Still’s passion for plants, education and professional networking that he has led the PPA.

Today, the Association represents the entire perennial industry and the national Perennial Plant Symposium is still the most important venue where the perennial industry meets. PPA provides education and networking through its membership outreach, six yearly symposia and publications. The award-winning Perennial Plant of the Year program, established in 1990, continues to promote perennials to the public.

“The industry has grown radically since the 1980s and the once cottage industry continues to grow, diversify, and specialize,” said Dr. Still. “This strength is a reflection of connections fostered among PPA members. What an awesome and rewarding experience it has been to work with passionate plants people, savvy business people and dedicated volunteers. We've accomplished a great deal and our work continues.”
