Thank you for your interest in joining the Perennial Plant Association (PPA)!


This is THE association for horticulture professionals, educators, and avid gardeners interested in the herbaceous perennial industry.


Please note that our membership year runs from Oct. 1 through Sept. 30.



We host the National Symposium every year for our perennial plant people! 
Our symposium is the place to connect with your fellow perennial plant experts, geeks, and enthusiasts. Unfortunately, the 2020 National Symposium has been cancelled due to the Coronavirus pandemic.  We will be back in Lancaster, PA in 2021.

For 2020, check out PPA: Virtual Edition!
