Back To Columbus

Just as perennials come back every year, the Perennial Plant Association (PPA) will return to Columbus, Ohio, to celebrate the silver anniversary of its first Perennial Plant Symposium.

Dr. Steven Still, an emeritus landscape horticulture professor at The Ohio State University (OSU), organized the very first symposium in 1983. The response was so overwhelmingly favorable, perennial growers formed an association of their own the next year. Still has been the executive director ever since.

Today, PPA has more than 1,800 members and draws more than 1,000 perennial professionals to its symposium. The program appeals to growers, retailers, landscapers and allied industry members. Here’s what’s planned for growers on this year’s program at the Hyatt Regency Columbus.
