Welcome to the 36th Annual Perennial Plant Symposium!

The Perennial Plant Symposium is the only yearly symposium devoted entirely to perennials. This industry-focused conference brings together more than 500 professionals for networking, learning, and special events. The symposium moves to a different region each year, giving participants a unique experience and insight into the region’s perennial scene.

This year’s symposium takes place at the Hilton North Raleigh/Midtown, in the horticulturally vibrant Raleigh-Durham, North Carolina region. You can explore outstanding local gardens, visit vibrant retail garden centers, and tour innovative production facilities. You’ll also hear and engage with industry experts from around the world. Most importantly, you’ll spend time with the best in the industry.

  • The PPA 2018 Symposium E-Brochure is now available to download. This brochure provides attendees with a detailed overview of all the happenings and events throughout the symposium. Feel free to share the content with colleagues and friends!
  • The symposium also welcomes perennial enthusiasts with a full day of Plant Talks on Monday, which are open to the general public and industry professionals!
  • If you have extra time and want to explore the city of Raleigh on your own, or if you are just looking for a quick bite to eat in between Trade Show hours, download and print our On Your Own Guide, with places to go and things to see, recommended by the local site committee.
