National Symposium

The Perennial Plant Symposium is the only yearly symposium devoted entirely to perennials. It is also the oldest with the first symposium presented in 1983. The location changes each year.  Enjoy learning about and observing perennials, gardens, and production facilities all across the USA and Canada. Perhaps best of all, you'll network with the best in the industry.
